being tested i.e. the sampling should be spread over the entire period of concreting and cover all mixing

units. NOTE : At least 1 sample shall be taken from each shift. Ten test specimens shall be made from each

sample, 5 for testing at 7 days and the remaining 5 at 28 days. The samples of concrete shall be taken on

each day of the concreting as per above frequency. The number of specimens may be suitably increased

as deemed necessary by the Architect and Engineer-in charge when procedure of tests given above

reveals a poorquality of concrete and in other special cases.

The average strength of the group of cubes cast for each day shall not be less than the specified cube

strength of 250 Kg/cm2. at 28 days. 20% of the cubes cast for each day may have value less than the

specified strength provided the lowest value is not less than 85% of the specified strength. If the concrete

made in accordance with the proportions given for a particular grade, does not yield the specified strength,

such concrete shall be classified as belonging to the appropriate lower grade. Concrete made in accordance

with the proportions given for a particular grade shall not, however, be placed in a higher grade on the

ground that the test strength are higher than the minimum specified.

If rock pockets/honeycombs in the opinion of Architect and Engineer-in-charge are of such an extent or

character so as to effect the strength of the structure, materially or to endanger the life of the steel

coarse aggregate for Wetmix macadam.

Preparation of Mix

Wet Mix Macadam should be prepared in an approved mixing plant of suitable capacity having

provision for controlled addition of water and forced/positive mixing arrangement like pugmill or pan

type mixer of concrete batching plant. For small quantity of wet mix work, the Engineer may permit

the mixing to be done in concrete mixers.

Quantity of water should not vary from OMC determined as per IS : 2720 (part VIII) by more than

agreed limit. The mixed material should be uniformly wet and no segregation should be permitted.

Spreading of mix

Immediately after mixing, the aggregates shall be spread uniformly and evenly upon the prepared sub

grade/sub-base/base in required quantities. In no case should these be dumped in heaps directly on

the area where these are to be laid nor shall their hauling over a partly completed stretch be

The mix may be spread either by a paver finisher or motor grader or as per instruction of Engineer-in-

Charge and/or his authorized representative. For portions where mechanical means cannot be used,

manual means as approved by the Engineer shall be used. The motor grader shall be capable of

spreading the material uniformly all over the surface. Its blade shall have hydraulic control suitable for

initial adjustments and maintaining the same so as to achieve the specified slope and grade.

aggregates as spread should be of uniform gradation with no pockets of fine materials.

After the mix has been laid to the required thickness, grade and crossfall/camber the same shall be

uniformly compacted, to the full depth with suitable roller. If the thickness of single compacted layer

does not exceed 100 mm, smooth wheel roller of 80 to 100 kN weight may be used. For a compacted

single layer upto 200 mm, the compaction shall be done with the help of vibratory roller of minimum

static weight of 80 to 100 kN or equivalent capacity roller. The speed of the roller shall not exceed

In portions having unidirectional cross fall/superelevation, rolling shall commence from the lower

edge and progress gradually towards the upper edge. Thereafter, roller should progress parallel to the

centre line of the road, uniformly over-lapping each preceding track by at least one third width until

the entire surface has been rolled. Alternate trips of the roller shall be terminated in stops at least 1 m

away from any preceding stop.

In portions in camber, rolling should begin at the edge with the roller running forward and backward

until the edges have been firmly compacted. The roller shall then progress gradually towards the

centre parallel to the centre line of the road uniformly overlapping each of the preceding track by at

least one-third width untilthe entire surface has been rolled.

Any displacement occurring as a result of reversing of the direction of a roller or from any other

cause shallbe corrected at once as specified and/or removed and made good.

Along forms, kerbs, walls or other places not accessible to the roller, the mixture shall be thoroughly

compacted with mechanical tampers or a plate compactor. Skin patching of an area without scarifying

the surface to permit proper bonding of the added material shall not be permitted.

Rolling should not be done when the sub grade is soft or yielding or when it causes a wave-like motion

in the sub-base/base course or sub grade. If irregularities develop during rolling which exceed 12 mm

when tested with a 3 metre straight edge, the surface should be loosened and premixed material

added or removed as required before rolling again so as to achieve a uniform surface conforming to

the desired grade and cross fall. In no case should the use of unmixed material be permitted to

make up the depressions. Rolling shall be continued till the density achieved is at least 98 per cent of

the maximum dry density for the material as determined by the method outlined in IS : 2720 (Part-8).

After completion, the surface of any finished layer shall be well-closed, free from movement under

compaction equipment or any compaction planes, ridges, cracks and loose material. All loose,

segregated or otherwise defective areas shall be made good to the full thickness of the layer and

procedure shall be adopted to ensure that each concrete batch shall have a reasonable chance of

being tested i.e. the sampling should be spread over the entire period of concreting and cover all

At least 1 sample shall be taken from each shift. Ten test specimens shall be made from each sample,

for testing at 7 days, and the remaining 5 at 28 days. The samples of concrete shall be taken on each

day of the concreting as per above frequency. The number of specimens may be suitably increased as

deemed necessary by the Engineer-in-charge when procedure of tests given above reveals a poor

quality of concrete and in other special cases. The average strength of the group of cubes cast for each

day shall not be less than the specified cube strength of 200 Kg/cm2 at 28 days. 20% of the cubes cast

for each day may have value less than the specified strength provided the lowest value is not less than

85% of the specified strength. If the concrete made in accordance with the proportions given for a

particular grade, does not yield the specified strength, such concrete shall be classified as belonging to

the appropriate lower grade. Concrete made in accordance with the proportions given for a particular

grade shall not, however, be placed in a higher grade on the ground that the test strength are higher

than the minimum specified. If rock pockets/honeycombs in the opinion of Engineer-in-charge are of

proportions shall be maintained during subsequent concrete batching by means of weigh batchers capable of

controlling the weights within one percent of the desired value. Amount of water added shall be such as to

produce dense concrete of required consistency, specified strength and satisfactory workability and shall be so

adjusted to account for moisture content in the aggregates. Water cement ratio specified shall be maintained.

Each time the work stops, the mixer shall be cleaned out, and while recommending the first batch shall have

10% additional cement to allow for sticking in the drum, Arrangement should be made by contractor to have the

cubes tested in an approved laboratory or in field at his own expense, with prior consent of Engine4re. Sampling

proportions to yield the specified strength.

BATCHING AND MIXING CONCRETE

Based on the adopted nominal mixes, aggregates and cement shall be measured by weight.

PREPARATION PRIOR TO CONCRETE PLACEMENT

Before concrete is actually placed in position, the inside of the form work shall be cleaned and mould oil applied,

inserts and reinforcement shall be correctly positioned and securely held, necessary openings pockets etc.

All arrangements formwork, equipment and proposed procedure, shall be approved by Engineer. The Contractor

shall maintain separate Pour Card for each pour as per the format enclosed and shall produce before

commencement of concreting to Engineer-in-charge.

TRANSPORTING, PLACING AND COMPACTING CONCRETE

Concrete shall be transported from the mixing plant to the formwork with minimum time lapse by methods that

shall maintain the required workability and will prevent segregation, loss of any ingredients or ingress of foreign

matter or water.

In all cases concrete shall be deposited as early as practicable directly in its final position. To avoid segregation

concrete shall not be re-handled or caused to flow. For locations where direct placement is not possible and in

narrow forms. The Contractor shall provide suitable drops and “Elephant Trunks” Concrete shall not be dropped

from a height of more than 1.0 mm as stipulated in clause D.6.8.13.

Concrete shall not be placed in flowing water. Under water, concrete shall be placed in position by tremies or by

pipeline from the mixer and shall never be allowed to fall freely through the water. While placing concrete the

Contractor shall proposed as specified below and also ensure the following:

a) Continuously between construction joints and predetermined abutments.

b) Without disturbance to forms or reinforcement.

c) Without disturbance to pipes, ducts, fixings and the like to be cast in; ensure that such items are securely

fixed. Ensure that concrete cannot enter open ends of pipes and conduits etc.

d) Without dropping in a manner that could cause segregation or shock.

e) In deep pours only when the concrete and framework designed for this purpose and by using suitable chutes

f) Do not place if the workability is such that full compaction cannot be achieved.

g) Without disturbing the unsupported sides of excavations; prevent contamination of concrete with earth.

Provide sheeting if necessary. In supported excavations, withdraw the lining progressively as concrete is placed.

h) If placed directly on to hardcore or any other porous material, dampen the surface to reduce loss of water

from the concrete.

i) Ensure that there is no damage or displacement to sheet membranes.

j) Record the time and location of placing structural concrete. Concrete shall normally be compacted in its final

position within thirty minutes of leaving the mixer. Concrete shall be compacted during placing with approved

vibrating equipment without causing segregation until it forms a solid mass free from voids thoroughly worked

around reinforcement and embedded fixtures and into all corners of the formwork. Immersion vibrators shall be

inserted vertically at points not more than 450 mm apart and withdrawn slowly till air bubbles cease to come to

surface, leaving no voids. When placing concrete in layers advancing horizontally, care shall be taken to ensure

adequate vibration, blending and melding of concrete between successive layers. Vibrators shall not be allowed

come in contract with reinforcement, formwork and finished surfaces after start of initial set. Over vibration

shall be avoided.Concrete may be conveyed and placed by mechanically operated equipment after getting the

complete procedure approved by Engineer. The slump shall be held to the minimum necessary for conveying

concrete by this method. When concrete is to be pumped concrete mix shall be specifically designed to suit

pumping. Care shall be taken to avoid stoppages in work once pumping has started.Except when placing with

slip forms, each placement of concrete in multiple lift work, shall be allowed to set for at least 24 hours after the

final set of concrete before the start of subsequent placement. Placing shall stop when concrete reaches the top

of the opening in walls or bottom surface of slab, in slab and beam construction, and it shall be resumed before

concrete takes initial set but not until it has had time to settle as determined by Engineer. Concrete shall be

protected against damage until final acceptance.

Curing and protection shall start immediately after the compaction of concrete to protect it from:

(a) Premature drying out, particularly by solar radiation and wind;

(b) Leaching out by rain and flowing water;

(c) Rapid cooling during the first few days after placing;

(d) High internal thermal gradients;

(e) Low temperature of frost;

(f) Vibration and impact which may disrupt the concrete and interfere with its bond to the reinforcement.All

concrete, unless directed otherwise by Engineer, shall be cured by use of continuous sprays or pounded water or

continuously saturated coverings of sacking, canvas, hessian or other absorbent material for the period of

complete hydration with a minimum of 7 days. The quality of curing water shall be the same as that used for

mixing.Where a curing membrane is directed to be used by the Engineer, the same shall be of a non-wax base

and shall not impair the concrete finish in any manner. The curing compound to be used shall be got approved

from the Engineer before use and shall be applied with spraying equipment capable of a smooth, even textured

coat. Curing may also be done by covering the surface with an impermeable material such as polyethylene,

which shall be well sealed and fastened. Extra precautions shall be exercised in curing concrete during cold and

CONSTRUCTION JOINTS AND KEYS

Construction joints will be as shown on the drawing or as approved by Engineer. Concrete shall be placed

without interruption until completion of work between construction joints. If stopping of concreting becomes

unavoidable anywhere, a properly formed construction joint shall be made with the approved of Engineer.

Dowels for concrete work, not likely to be taken up in the near future, shall be coated with cement slurry and

encased in lean concrete as indicated on the drawings or as directed by Engineer. Before resuming concreting on

a surface which has hardened all laitance and loose stone shall be thoroughly removed by wire brushing/hacking

and surface washed with high pressure water jet and treated with thin layer of cement slurry for vertical joints

and a 15 mm thick layer of cement sand mortar for horizontal layers, the ratio of cement and sand being the

same as in the concrete mix. When concreting is to be resumed on a surface which has not fully hardened, all

laitance shall be removed by wire brushing, the surface wetted, free water removed and a coat of cement slurry

applied. On this a layer of concrete not exceeding 150 mm thickness shall be placed and well rammed against

the old work. There after work shall proceed in the normal way.

FOUNDATION BEDDING

All earth surfaces upon which or against which concrete is to be placed, shall be well compacted and free

from standing water, mud or debris. Soft or spongy area shall be cleaned out and back filled with either soil

cement mixture, lean concrete or clean sand compacted as directed by Engineer. The surfaces of absorptive

soils shall be moistened.

The frame work for concrete works shall be such as to give the finish as specified; defects due to bad

workmanship (e.g. damaged or misaligned forms, defective or poorly compacted concrete) will not be

accepted. The Contractor shall construct the formwork using the correct materials and to meet the

requirements of the design and to produce finished concrete to required dimensions, plumbs, planes and

REPAIR AND REPLACEMENT OF UNSATISFACTORY CONCRETE

Immediately after the shuttering is removed, all the defective areas such as honey combed surfaces, rough

patches, holes left by form bolts etc. shall be brought to the notice of Engineer who may permit patching of the

defective areas or reject the concrete work. All though holes for shuttering shall be filled for full depth and

neatly plugged flush with surface. Rejected concrete shall be removed and replaced by Contractor at no

additional cost to Client.For patching of defective areas all loose materials shall be removed and the surface

shall be prepared as directed by the Engineer.Bonding between hardened and fresh concrete shall be done

either by placing cement mortar or by applying epoxy. The decision of the Engineer as to the method of repairs

to be adopted shall be final and binding on the Contractor and no extra claim shall be entertained on this

account. The surface shall be saturated with water for 24 hours before patching is done with 1:5 cement sand

mortar. The use of epoxy for bonding fresh concrete shall be carried out as directed by Engineer.

HOT WEATHER REQUIREMENTS

Concreting during hot weathers shall be carried out as per IS: 7861 (Part-I) Adequate provisions shall be made to

those others specifically called for to guarantee the finish and water tightness. The minimum level of surface

finish for liquid retaining structures shall be as per clause D.6.16. All such structures shall be hydro-tested.The

contractors shall include in his price of hydro-testing of structure, all arrangements for testing such as temporary

bulk heads, pressure gauges, pumps, pipelines etc.Any temporary arrangements that may have to be made to

ensure stability of the structures shall also be considered to have been taken into account while quoting the

rates.Any leakage that may occur during the hydro-test or subsequently during the defects liability period or the

period for which the structure is guaranteed shall be effectively stopped either by cement/epoxy pressure

grouting, gunting or such other methods as may be approved by the Engineer. All such rectification of the Client

/ Engineer at no extra cost to the Client.

TESTING CONCRETE STRUCTURE FOR LEAKAGE

Hydro-static test for water tightness shall be done at full storage by Engineer, as described below:

In case of structures whose external faces are exposed, such as elevated tanks, the requirements of the test

shall be deemed to be satisfied if the external faces show no sign of leakage or sweating and remain completely

dry during the period of observation of seven days after allowing a seven day period for absorption after filling

with water.In case of structures whose external faces are submerged and are not accessible for inspection, such

as underground tanks, the structures shall be filled with water and after the expiry of seven days after filling,the

level of the surface of the water shall be recorded. The level of water shall be recorded again at subsequent

intervals of 24 hrs, over a period of seven days. Backfilling shall be withheld till the tanks are tested. The total

drop in surface level over a period for seven day shall be taken as an indication of the water tightness of the

structure. The Engineer shall decide on the actual permissible nature of this drop in the surface level, taking into

account weather the structures are open or closed and the corresponding effect it has on evaporation losses.

Unless specified otherwise, a structure whose top is covered shall be deemed to be water tight if the total drop

in the surface level over a period of seven days does not exceed 40 mm.

Each compartment/segment of the structure shall be tested individually and then all together.For structures

such as pipes, tunnels etc. the hydro-static test shall be carried out by filling with water, after curing as specified,

and subjecting to the specified test pressure for specified period. If during this period the loss of water does not

exceed the equivalent of the specified rate, the structure shall be considered to have successfully passed the

If Engineer feels that the materials i.e. .cement, sand coarse aggregates, reinforcement and water are not in

accordance with the specifications or if specified concrete strengths are not obtained, he may order tests to be

carried out on these materials in laboratory, to be approved by the Engineer, as per relevant IS Codes. Client

shall pay only for the testing of material supplied by the Client, otherwise Contractor shall have to

pay for the tests. Transporting of all material to the laboratory shall however be done by the Contractor at no

extra cost to client.In the even of any work being suspected of faulty material or workmanship requiring its

removal or if the works cubes do not give the stipulated strengths, Engineer reserves the right to order the

Contractor to take out cores and conduct tests on them or do ultrasonic testing or load testing of structure, etc.

All these tests shall be carried out by Contractor at no extra cost to the Client. Alternatively Engineer also

reserves the right to ask the Contractor to dismantle and re-do such unacceptable work at the cost of

Contractor.If the quoted unit rates/prices of concrete shall be deemed to provide for all tests mentioned above.

All materials, workmanship and finished construction shall be subject to continuous inspection and approval of

Engineer. Materials rejected by Engineer shall be expressly removed from site and shall be replaced by

Contractor immediately at no extra cost to Client.
