        x.    CRS Sanction.        
Ans.- ( i ) Cant Deficiency and Cant Excess –
Cant Deficency –
Cant Deficency occurs when a train travels around a curve at a speed higher than the equilibrium speed. It is the difference between the theoretical cant required for such higher speed and actual cant provided.
Cant excess –
Cant excess occurs when a train travels around a curve at a speed lower than equilibrium speed. It is the difference between the actual cant and the theoretical cant required for such lower speed.
( ii ) Switch & Expansion joint and Breathing Length -
Switch  & Expansion Joint ( SEJ ) –
Switch Expansion, Joint (SEJ) is an expansion joint installed at each end of LWR/CWR to permit expansion/contraction of the adjoining breathing lengths due to temperature variations.
The exact location of SEJ shall be fixed taking into account the location of various obligatory paints such as level crossings, girder bridges, points and crossings gradients, curves and insulated joints. SEJ with straight tongue and stock shall not be located on curves sharper than 0.5 degree (3500 m radius) as far as possible. SEJ shall not be located on transition of curves.
Breathing length of LWR –
Breathing Length is that length at each end of LWR/CWR, which is subjected to expansion/contraction on account: of temperature variations. Usual breathing lengths in BG for different types of track structures and for different temperature zones as laid down.

 ( iii ) Free Board & Clearance -
Free Board – This is the vertical distance between the high flood level inclusive of afflux and the formation level.
Clearance - This is the vertical distance between the high flood level inclusive of afflux and the bottom most part of bridge super structure like slab girder etc.

( iv ) Scour Depth and Danger Level –
Depth of Scour-
The maximum scour depth in a stream can be ascertained when ever possible by actual sounding at or near the site proposed for the bridge during or immediately after a flood. Before the scour holes have had time to silt up due to allowance should be made in the observed depth for increase in scour resulting from-
  1. The designed discharge being greater than the flood discharge during which the scour was observed.
  2. The increase in velocity due to the obstruction in flow caused by construction of the bridge.
Where the above practical method of determining scour is not possible the following theoretical method may be used as a guide when dealing with natural streams is alluvial beds.       D = 0.473 [ Q / F ] 
Where D = Depth of scour below HFL for regime conditions in a stable channel in meters.
           Q = Design discharge in cumecs.  
           F= Silt factor = 1.76 √ m , m is the mean diameter of particles in mm.
Danger level –
It is not possible to lay down any adhoc levels for fixing danger levels. It has to be decided on the spot for each and every individual bridge depending upon the site conditions. Local conditions such as nature of bed, condition of approach bank, depth of foundation & free board to be allowed should influence the decision.
The marking of danger level would imply that is would be safe for the flood water to reach up to the danger level with out affecting the safety of the bridge structure or of its foundations or approaches. Danger level for a particular bridge should be fixed after site inspection, examination of records of past history, local enquiries about flood, afflux and velocity of water under bridge.

( v ) Private & Assisted Siding -
Assisted Siding –
An Assisted Siding is a siding to serve a factory, mill or other industrial premises other than colliery or mining are because such siding is anticipated to attract competitive traffic to the Railway.

2)    The applicant should deposit the estimated cost of his portion of the work before the construction of the siding is taken up.
3)    The cost of land to be acquired for the siding out side the applicant’s premises should be borne by the applicant.
4)    The incidence of cost of the siding out side the applicant’s premises will be as follows –
a)      The cost of all works which would have to be abandoned in the event of the siding being closed e.g. earth work, bridge work, culverts, buildings etc should be borne by the applicant.
b)      The cost of all works which would be removed by the railway administration in the event of the siding being closed such as rails sleeper’s fastenings, points & crossing, girder work of bridges, signaling & interlocking appliances and machinery of any kind should be borne by the Railway Administration.
5)    Over head electric traction equipment whether on railway land or on private land should be paid by the Railway Administration and will remain as Railway property.
6)    The entire cost of the siding within the applicant’s premises should be borne by the applicant.
( vi ) Security Deposit & Earnest money –
Security Deposit – A Security deposit is taken for the satisfaction of and efficient execution of the work within the agreed time from contractors. Such Security deposit may also be percentage deduction from on accounts bills of contractors called as retention Money usually 10% of the gross amount of bill.

 ( vii ) Catch siding & Slip Siding -
Catch Sidings
Normally all catch sidings except those which are sanded shall be kept alive. On sanded catch siding, the rails shall be kept clear of sand for a length of 21.5 metres, beyond the section insulators in the overhead lines and the switches controlling the sanded catch sidings shall be kept in the neutral position. If an electric engine or single or multiple unit train runs into the sanded length of a catch siding, it may possibly be insulated from earth except through the buffers or couplings if connected to other vehicles, therefore these sidings shall not be made alive when an electric engine or single or multiple unit train or any vehicle coupled thereto are standing in the sanded tracks until all staff have been moved away from positions where they are likely to make contact between the permanent way formation and any part of the locomotive or single or multiple unit train or coupled vehicles. No person shall attempt to enter, or leave or in any other way make contact between the permanent way formation and the electric engine or single or multiple unit train or any vehicles coupled thereto while the overhead equipment of the sanded length of siding is alive.
Slip Siding –
If the Station yard is in a gradient steeper than 1 in 260 or there is a continuous falling gradient away from the station there is a possibility of vehicles standing in the yard entering or escaping into the block section and cause accidents to prevent such escaping of vehicles into the block section slip siding are provided.
At a station where there is a gradient 1 in 100 falling away from the station within 45 meters beyond the outer most points at either end a slip siding should be provided.
As per the schedule of dimensions no station yard should be constructed nor should any siding join a passenger line on a steeper grade than 1 in 260 except where it is unavoidable and then only with the previous sanction of the railway board obtained through the commissioner of Railway safety when a slip siding is made sufficient prevent accident.
( viii ) Temporary & Permanent Speed restriction and Engineering Allowance -

(a) Caution indicator.
(b) Speed indicator.
(c ) Stop indicator.
(d) Termination indicators ( T/P & T/G).
Permanent speed restriction -
Permanent speed restrictions in force are notified in working time-tables. The speed indicators are erected to indicate to the Drivers the speed restrictions to be observed e.g., between stations, and at stations due to weaker/non standard track/ bridges, restrictions on curves, grades and points and crossings etc.
The indicators to be used are similar to those used for temporary restrictions, namely, caution indicator, speed/stop indicators and termination indicators (T/P&T/G). The details of the indicators and the distance at which they are to be fixed are the same in both the cases
The permanent indicators need not be flood lit at night as in the case of temporary indicators/ signals.

( b ) USFD testing of rails and welds
Rails & weld failure can be detect by USFD Ultrasonic flow detection test. A defect in rail which will ultimately lead to the fracture or breakage of rail is called a flow. Thus it is necessary to detect these flows and take timely action to remove them.
The detection of rail flows can be done either by visual examination of rail end or by Rail flow detection equipment.
Q.9.- As AEN in charge you have to carry out 3.0 Km of CTR with 60 Kg 10 rail welded panels on MBC sleepers of existing LWR main line track of 52 KG. on CST9 sleepers. Broadly give the planning and steps involved for execution of this work from start to finish in a financial year.                                                                                             
Ans.- Planning of Renewals – Renewals may be planned in as long and continuous lengths as practicable, within the available resources with priorities to meet the projected traffic. Short isolated stretches of 3 kms. on condition basis may be programmed along with the adjoining lengths, if these stretches do not confirm to the required standards. Priority in planning renewals should be given to busy and important lines.
Track renewal programmes shall be framed by the Chief Engineer of each Railway taking into consideration the proposals submitted by the Divisional Engineers.
Track Renewal Programme
(1) Initiation of Proposals – Track renewal proposals are submitted to the Divisional Engineer by the Assistant Engineer on condition basis and also on the basis of various inspections carried out during the year. The Divisional Engineer shall personally check the details submitted by the Assistant Engineers at site and compile and initiate the track renewal programme indicating the priorities. The justification for track works shall be prepared on the basis of factually correct data and submitted in proforma. It shall include an abstract estimate of the cost of work and detailed narrative justification covering technical and financial aspects. The Divisional Engineer should personally satisfy himself about the reasonableness of the proposal and certify that the justification furnished is factually correct. The Assistant Engineer should keep a close watch on the condition of all track on their sub-divisions so that every length which after careful and judicious examination requires renewal, is included in the proposals, bearing in mind that the programme is prepared a year in advance and as much as two years may elapse before renewals are carried out. The proposals should reach the Chief Engineer’s Office by end of March.
(2)Verification of proposals by the Track Cell in the Chief Engineer’s Office – Important items relating to complete track renewal.
(a) Co-ordinate the proposals received from the divisions;
(b) Frame programmes for renewal taking into account the sections planned for renewal;
(c) Decide priority for the works;
(d) Satisfy himself that the renewal is unavoidable in the case of track renewal proposals which are justified primarily on condition basis but are premature as far as quantum of traffic carried (G.M.T.) is concerned.
(e) Finalise the track renewal programme and submit the same to the Chief Track Engineer/Chief Engineer for his approval. On receipt of Railway Board’s sanction to the track renewal programme, arrangements will be made by the Headquarters for supply of track materials to the Divisions and for coordinated execution and control over the works.
Q.10.- ( a ) What is mechanical compaction of earth work and what system you will observe for quality control and measurements and payments to the contractor? Draw the typical cross section of a double line track in bank and cutting.                       
           ( b ) What are the function of blanketing material and how its thickness is to be decided in case of earth work in railway bank.                                                        
Ans.- ( a ) Mechanical compaction of earth work -
Compaction is the process of increasing the density of soil by mechanical means by packing the soil particles closer together with reduction of air voids and to obtain a homogeneous soil mass having improved soil properties. Compaction brings many desirable changes in the soil properties as follows:
a) Helps soils to acquire increase in strength.
b) Reduces compressibility.
c) Increases density and reduces permeability.
d) Reduction in erodability.
e) Results in homogenous uniform soil mass of known properties.
f) Reduction in frost susceptibility in cold regions.
However, while compaction of earthwork is a necessary condition to achieve a stable formation, it does not help in checking against the following causes which needs to be taken care during the design of bank or cutting :
(i) Excessive creep or slipping of slopes .
(ii) Swelling and shrinkage characteristic of soils due to variation in moisture content.
(iii) Mud pumping at ballast - soil interface.
(iv) Settlements due to consolidation of bank.
Factors Affecting Compaction in the Field:- 
(a) Compacting Effort: In modern construction projects, heavy compaction machinery are deployed to provide compaction energy. Sheep foot rollers or pneumatic rollers provide the kneading action. Silty soil can be effectively compacted by Sheep foot roller/pneumatic roller or smooth wheel roller. For compacting sandy and gravelly soil, vibratory rollers are most effective. If granular soil have some fines both smooth wheeled and pneumatic rollers can be used.
(b) Moisture Control: Proper control of moisture content in soil is necessary for achieving desired density. Maximum density with minimum compacting effort can be achieved by compaction of soil near its OMC (Optimum Moisture Content). If natural moisture content of the soil is less than the OMC, calculated amount of water should be added with sprinkler attached to water tanker and mixed with soil by motor grader for uniform moisture content. When soil is too wet it is required to be dried by aeration to reach up to OMC.
(c) Soil Type: Type of soil has a great influence on its compaction characteristics.
(d) Thickness of Layer:-Layer thickness depends upon type of soil involved and type of roller its weight and contact pressure of its drums. Normally, 200 – 300 mm layer thickness is optimum in the field for achieving homogenous compaction.
(e) Number of Passes: Density of soil will increase with the number of passes of roller.
Method of Measurement and Payment -
            i.The initial rate for earthwork, carried out manually, will include the first lead of 50 metres and 2 metre lift free.
           ii.Lift from borrow pits to natural ground level is not to be taken into account in any payment for lift, unless the pit is deeper than 1.6 metres and then, only the portion below 1.5 metres will be allowed payment for additional lift.
          iii.The Engineer will then enter the reduced levels at which such soil is met on the relevant cross-section in his Classification Register, whenever a change of classification is involved, and obtain the initials of the Contractor on the reduced levels entered. 
          iv.In case of mechanical earthwork where the excavation is in ‘’All types of soil’’ the Engineer will enter the reduced level at the classification of rock requiring blasting
           v.In case of banks made up from cutting spoil, measurements of leads will be taken where necessary from the centre of gravity of the embankment mass, by using a mass diagram. However Mass diagram may not be prepared in case of mechanical earthwork where free lead in up to 1.0 km. and all lifts are included.
          vi.The quantity of work done will be arrived at from cross section measurements of banks. In the case of such measurement, all bridge structures, openings and other gaps and quantities are to be deducted in full as existing at the time of final measurement.
         vii.Rates for earthwork is inclusive of jungle of clearing, dressing and maintenance, and is also inclusive all plant and tools, maintenance of level pegs, construction of approach ramp, making berms, dressing of slopes, maintenance of earthwork through monsoon, stacking of released boulders from cuttings, construction of temporary approaches for execution of earthwork.
        viii.(j) Side drains in cuttings below formation level and catch water drains above cuttings will be paid for by measurement at the rates shown in the Schedule for excavation in cuttings.
Ans.- ( b ) Function of Blanketing Material -
              i.     It reduces traffic-induced stresses to a tolerable limit on the top of sub grade
             ii.     It prevents penetration of ballast into the sub grade.
            iii.     Its absence or inadequate thickness results in yielding formation and instability.
           iv.     Its absence may result in bearing capacity as well as progressive shear failure of sub grade soil.                                                 
            v.     It restricts plastic deformation of sub grade caused due to cyclic stresses induced by moving loads.
           vi.     It results in increased track modulus and thereby reduces track deformations.
          vii.     It facilitates drainage of surface water and reduces moisture variations in sub grade.                                                
         viii.     It prevents mud pumping by separating the ballast and sub grade soil.
           ix.     It ensures that the induced stress in sub grade are below the threshold stress of sub grade soil.
            x.     It ensures dissipation of excess pore water pressure developed in sub grade on account of cyclic loading and leads to increase in shear strength of sub grade soil.
           xi.     It obviates the need for formation rehabilitation work under running traffic at prohibitive cost.
          xii.     It leads to enhanced performance of sub grade as sub grade can serve designed functions more efficiently and effectively.
Depth of Blanket Layer: -
Depth of blanket layer of specified material depends primarily on type of sub grade soil and axle load of the traffic.
Depth of blanket to be provided for axle loads up to 22.5t for different types of sub grade soils (minimum top one meter thickness) has been given as under. In case more than one type of soil exists in top one meter then soil requiring higher thickness of blanket will govern.
Poorly graded Gravel ,  Poorly grade Sand , Silty Gravel , Silty Gravel , Clayey Gravel , soils shall need minimum 45cm thick Blanket.                     
Clayey Gravel , Silty Sand , Clayey Sand, Clayey Silty sand , soils shall need minimum 60cm thick Blanket.   Silt with low plasticity,  Silty clay of low plasticity, Clay of low plasticity, Silt of medium plasticity,  Clay of medium plasticity, Rocks which are very susceptible to weathering, types of soils shall need minimum 1m thick Blanket.

L.G.S. EXAMINATION – CIVIL ENGINEERING 008 – 02 - 2003

Q.1.- What is alphanumeric system of allocation of expenditure under revenue Grant and works grants? Give an example of such allocation of expenditure on an activity you are associated with.                                                                          
Ans.- The Revised Classification of expenditure on works irrespective of whether they are charged to Capital DRF, DF, Revenue (OLWR) or ACF will come under a single Demand-16 namely Assets-Acquisition , 'Construction and Replacement. The Accounting Classification for works expenditure is in the form of a 7 digit—4 module alphamerical code. The first module which is the alpha indicates the source of fund viz., Capital, DRF, DF, Revenue (OLWR) or ACF as the case may be. The second module of 2 digits which is numerical will represent the standard Plan Heads. The third module which is also numerical will represent the 2 digits corresponding to the sub and detailed head of classification giving the details of the assets acquired, constructed or replaced. The last module which is of two digits will indicate the primary unit i.e., object of the expenditure.
For example, when track renewals are undertaken the allocation of expenditure will be given as 3141 or 3142 for renewal of rails and fastenings or sleepers and fastening as the case may be. To these 4 digits will, however, be added the code for primary unit of expenditure viz., wages or materials etc. to complete the allocation e. g., 3141-04 will indicate the pay and allowances of departmental establishment engaged on renewals of rails and fastenings. The cost of Permanent Way materials etc. directly supplied for this work will be allocated to 3141-04 and so on.

( ix ) Septic Tank & Acqua Privy –
Septic Tank
Septic tank system is on a site disposal method which uses standard flushing. The septic tank acts as sedimentation cum digestion tank, Anaerobic digestion of the settled sludge occurs in its bottom zone and the supernatant liquid has to under go treatment in a soak pit / filter bed. Use of septic tank with out follow up treatment is not permitted, as the effluent from the septic tank is hazardous from the point of view of health and pollution, since it is usually not possible to provide sock pit / filter bed in built up urban areas, Septic tank system would not be appropriate in such areas.
Septic tank shall be air tight, the light and oxygen should be totally excluded. In order to create favorable atmosphere for anaerobic bacteria to develop the lighter part of the suspended matter in sewage floats on water colleted scum, the scum should not be disturbed for this purpose t out let and in let are provided. Scum board also may be provided at times to prevent scum being disturbed. Velocity of the sewage is reduced by allowing water to pass through opening at the bottom. The detention period of sewage is 10 to 12 hours.
Aqua Privy Latrine –
There are a sort of latrines also called septic tank latrines. These are constructed over septic tanks & flushing is also provided. The excreta together with flush water falls into the septic tank where it under goes anaerobic decomposition. The effluent flows to filters and then to soak pits. These tanks are designed for a capacity of 70 Liter / head / day and for a population even up to several thousands. A raw of water closets may be constructed over single septic tank. A grit chamber is necessarily provided at the inlet end of the septic tank which detains hard solid masses of faces which would other wise pass undigested at the other end . the grit chamber is made by erecting a wall at 1/6th the length of tank from in let side. This wall has an opening at the bottom so that excreta pieces are held on the surface in grit chamber till they are decomposed and digested while the main flow passes down through the opening at the bottom.
( x ) Chlorination –
The process of applying small quantities of chlorine   or chlorine compounds to water is called chlorination.
The form in which Chlorine can be applied may be any one of the following –
1. Bleaching powder 2. Hypochlorities   3. Chloramines   4. Chlorine dioxide    5. Liquid chlorine 6. Chlorine gas.
Chlorination should be done generally using chlorine Gas or other similar methods by Engineering department. At other places chlorination has to be done by mixing good quality bleaching powder solution at a particular rate with raw water in the pumping main at the pump house it self or at the high level storage Tanks by the IOW.

                    Permitted cant deficiency                          -  100 mm.
                    Permitted cant excess                               -  75  mm.                
Ans.-  ( a ) ( i ) Curve Compensation / Grade Compensation on curve -  
The ruling gradient is required to be compensated on curves to offset the extra resistance due to curvature. The curve resistance depends upon a number of variable factors but for simplicity reasons it is taken as a percentage per degree of curve. Compensation for curvature allowed on Indian Railways is as follows –
BG  -  0.04% per degree of curvature.
MG  -  0.03% per degree of curvature.
NG  -  0.02% per degree of curvature.
( ii ) Cant Deficency –
Cant Deficency occurs when a train travels around a curve at a speed higher than the equilibrium speed. It is the difference between the theoretical cant required for such higher speed and actual cant provided.
( iii ) Cant excess –
Cant excess occurs when a train travels around a curve at a speed lower than equilibrium speed. It is the difference between the actual cant and the theoretical cant required for such lower speed.
Ans.-  ( b )
                                 GV2      1750 x 802
Equilibrium cant = --------  =  ---------------  =  146.98 mm.
                                   127 R     127 x 600
                                                            1750 x 1102
Cant for maximum sectional speed = -----------------  = 277.88 mm.
                                                              127 x 600
Cant deficiency for maximum sectional speed = 277.88 - 146.98 = 130.90 mm.
which is more than the permitted cant deficiency of 100 mm. With 100 mm. Cd,
actual cant = 277.88 - 100 = 177.88 mm. But actual cant is to be limited to 165 mm.
Cant excess: Cant for a speed of 50 kmph. which is the booked speed of a goods train (assumed).
                                         1750 x 502
                                        ---------------   = 57.41 mm.
                                          127 x 600
Cant excess = 165 - 57.41 = 107.59 mm. which is in excess of 75 mm. permitted value.
Provide actual cant = 57.41+ 75 =132.41, say 130 mm.
Maximum permissible speed Vm = 0.27 Ö R(Ca+Cd)
= 0.27 Ö  600(130+100)
= 100.3 or 100 kmph
Length of transition -
(a) L = 0.008 x Ca x Vm = 0.008 x 130 x 100 = 104 M.
(b) L = 0.008 x Cd x Vm = 0.008 x 100 X 100 = 80 M
(c) L = 0.72 Ca = 0.72 x 130 = 93.6 M.
The maximum value obtained is 104 M.
Ans. – ( I )  Equilibrium cant  = 146.98 mm.
            ( ii ) Actual cant that can be provided on this curve = 177.88 mm. But actual cant is to be limited to 165 mm.
            ( iii ) Maximum permissible speed on this curve = 100 kmph.
            ( iv ) Length of the transition curve = 104 m.

           ( c ) Cube Tests & Slump Tests for prestressed concrete girder designed Mix.
           ( d ) Anti corrosion care of reinforcement bars in concrete work in saline environment.
Ans.- ( a ) Geo-technical investigations to get the soil particulars as necessary, for the design of foundations. For the satisfactory design and construction of piles, detailed soil   exploration to a depth generally not less than 10 metres below the   anticipated level of pile tip (unless bed rock or firm strata has been  encountered earlier) should be carried out and the following particulars  are collected.
a) Ground water table and its tidal and seasonal fluctuations;
b) Soil profile and bore hole log;
c) In-situ bulk and dry density ;
d) Index properties of soil ;
e) Shear properties of soil.  If required Standard Penetration Test (SPT) may be done;
f) Consolidation properties, in case of clays ;
g) Chemical analysis of soil and ground water to identify sulphate  and chloride content or any other deleterious chemical content.
Additional data such as high flood level, maximum scour depth , normal water level during working season, etc.  should also be collected.
( b ) Raker & under Reamed Piles -
Under Reamed Piles –
Under Reamed Piles mainly used in shrinkable soils ( black cotton soils ) to over come the effect of differential settlement due to volumetric change in soil effected by seasonal variations. It can also be used for sandy and clayey soils. These are three type –
        i.Single under reamed piles.
       ii.Double under reamed piles.
     iii.Multiple under reamed piles.
The diameter of under reamed bulb is normally 2.5 times the pile diameter and spacing of bulb should not exceed 1.5 times of the bulb. The minimum diameter of piles should be 20 cm. The top most bulb should be at minimum depth of two times of the bulb diameter. Minimum spacing of piles should be two times the bulb diameter.
( c ) Cube Tests & Slump Tests –
Cube Tests -
Cube Tests to be done for determine desired compressive strength of concrete. Sample consisting of six cubes 15 x 15 x 15 cm shall be taken for every 20 cum or part thereof of concrete work ignoring any part less than 5 cum or as often as considered necessary by the Engineer in charge. A register of cubes shall be maintained at the site of work. Cube tests to be done 7 days test and 28 days test.
Slump Tests –
Slump Tests to be done for determine desired workability of concrete. The workability of concrete can be measured by Slump Test.
Slump test is commonly adopted for ordinary concrete works. This test is performed with the help of a vessel of the shape of the frustum of a cone and open at both ends. The top and bottom diameters of the vessel should be 100 mm and 200 mm respectively and it should be 300 mm in height.
The vessel is placed in a flat non-absorbent surface and then filled with specimen concrete mix in four different layers of equal thickness. Each layer is tamped 25 times by the point of a 16 mm dia rod, 60 cm. In length. The strokes are applied uniformly over the entire area with a force that the rod just penetrates the full depth of the layer being compacted . Immediately after the vessel is completely filled, it is raised vertically, care being taken not to disturb the filling. The concrete filling is allowed to subside or settle. The vertical settlement recorded for concrete is known as slump.
The slump test gives satisfactory results for concrete mix of medium to high workability. It however, dose not give correct indication for concrete of low workability (suitable for compaction by vibration) which may give zero slump.
( d ) Anti corrosion care of reinforcement bars in concrete work in saline environment –
Anti corrosion care of reinforcement bars should be done by Cement polymer compost coating system. This system consists application of one coat rapid setting primer followed by a coat of cement polymer sealing product. The primer and sealing products have thermoplastic acrylic resin as basic raw material. Sealing product is formulated with resin mixed with cement as pigments.
 The coating is applied to the cleaned surface as soon as after cleaning and before oxidation of the surface. A rapid setting primer shall be applied over the prepared surface of the reinforcing steel either by brushing or dipping. After 30 minutes of application of the primer a cement polymer sealing coat shall be applied either by brushing or dipping. The coated rods shall be handled after 6 hours.
