The batching equipment shall be capable of determining and controlling the prescribed amounts of various constituent materials for concrete accurately i.e. water, cement, sand, individual size of coarse aggregates etc. The accuracy of the measuring devices shall fall within the following limits.

Measurement of Cement : ±2% of the quantity of cement in each batch

Measurement of Water : ±3% of the quantity of water in each batch

Measurement of Aggregate : ±3% of the quantity of aggregate in each batch

Measurement of Admixture : ±3% of the quantity of admixture in each batch

1.10 Mixing Concrete

The mixer in the batching plant shall be so arranged that mixing action in the mixers can be observed from the operator's station. The mixer shall be equipped with a



mechanically or electrically operated timing, signaling and metering device which will indicate and assure completion of the required mixing period. The mixer shall have all other components as specified in 15:4925.

1.11 Transportation, Placing and Compaction of Concrete

Mixed concrete from the batching plant shall be transported to the point of placement by transit mixers the mixing speed shall not be less than 4 rev/min. of the drum nor greater than a speed resulting in a peripheral velocity of the drum as 70 m/minute at its largest diameter. The agitating speed of the agitator shall be not less than 2 rev/min. nor more than 6 rev/min. of the drum. The number of revolutions of the mixing drum or blades at mixing speed shall be between 70 to 100 revolutions for a uniform mix, after all ingredients, have been charged into the drum. Unless tempering water is added, all rotation after 100 revolutions shall be at agitating speed of 2 to 6 rev/min and the number of such rotations shall not exceed 250. The general construction of transit mixer and other requirements shall conform to IS:5892.

Except where otherwise agreed to by the Engineer-in-Charge, concrete shall be deposited in horizontal layers to a compacted depth of not more than 450 mm. Unless agreed to by the Engineer- in-Charge, concrete shall not be dropped into place from a height exceeding 2 m. In order to avoid such situations chutes, tremie pipe or closed bottom buckets shall be used. These shall be kept clean and used in such a way as to avoid segregation. Slope of the chute shall be so adjusted that concrete flows without the use of excessive quantity of water. The delivery end of chute shall be as close as possible to the point of deposit. The chute shall be thoroughly flushed with water before and after each working period and the water used for this purpose shall be discharged outside the formwork. The concrete shall be compacted by using immersion type vibrators. When the concrete is being continuously deposited to a uniform depth along a member, vibrator shall not be operated within one meter of free end of the advancing concrete. Every effort shall be made to keep the surface of the previously placed layer of concrete such that the succeeding layer can be amalgamated with it by the vibration process. In case the concrete in underlying layer has hardened to such an extent that it cannot be penetrated by the vibrator but is still fresh (that is, just after initial set), bond shall be achieved between the top and underlying layer by first scarifying the lower layer before the new concrete is placed by systematically and thoroughly vibrating the new concrete. The points of insertion of vibrator in the concrete shall be so spaced that the range of action overlap to some extent and the freshly filled concrete is sufficiently consolidated at all locations. The spacing between the dipping positions of vibrator shall be maintained uniformly throughout the surface of concrete so that concrete is uniformly vibrated. The vibrating head shall be regularly and uniformly inserted in the concrete so that it penetrates of its own accord and shall be withdrawn slowly whilst running so as to allow redistribution of concrete in its way and allow the concrete to flow back into the hole behind the vibrator. The vibrator head shall be kept in one position till the concrete within its influence is completely consolidated. Vibration shall be continued until the coarse aggregate particle have blended into the surface but have not disappeared. The contractor shall keep at least one additional vibrator in serviceable condition to be used in the event of breakdowns and maintenance problems.



The formwork shall be strong and great care shall be exercised in its assembly. It shall be designed to take up increased pressure of concrete and pressure variations caused in the neighborhood of vibrating head, which may result in excessive local stress on the formwork. The joints of the formwork shall be made and maintained tight and close enough to prevent the squeezing out slurry or sucking in of air during vibration. The formwork to receive concrete shall be cleaned and made free from standing water, dust, etc. The contractor shall keep provision for screed and shutter vibrators at site.

No concrete shall be placed in any part of the structure until the approval of Engineer-in- Charge has been obtained. If concreting is not started within 24 hours of the approval being given, it shall have to be obtained again from the Engineer-in-Charge. Concreting shall be done continuously over the area between construction joints. Fresh concrete shall not be placed against concrete, which has been in position for more than 30 minutes unless a proper construction joint is formed. When concreting has to be resumed on a surface which has hardened, it shall be roughened, swept clean, thoroughly wetted and covered with a 13 mm thick layer of mortar composed of cement and sand in the same ratio as in the concrete mix itself. The 13 mm layer of mortar shall be freshly mixed and placed immediately before placing of new concrete.

Where concrete has not fully hardened, laitance shall be removed by scrubbing the wet surface with wire or bristle brushes. Care shall be taken to avoid dislodgement of particles of coarse aggregate. The surface shall then be thoroughly wetted, free water removed and then coated with neat cement grout. Particular attention shall be given to corners and close spots.

1.12 Concreting of Narrow Members

Wherever the concreting of narrow member (as adjudged by Engineer-in-Charge) is required to be carried out within shuttering of considerable depth, temporary openings in the sides of the shuttering shall if so desire by the Engineer-in- charge, be provided to facilitate the pouring and consolidating of the concrete. Before any concreting is commenced, shutters and centering shall be carefully examined and the space to be occupied by the concrete be thoroughly cleaned out. The concrete in such members shall be compacted using suitable surface vibrator as appropriate.

1.13 Surface Finish

The exposed surface of concrete of all grades shall be shutter finished.

The finished concrete surfaces shall be free from honeycomb, blemishes, holes, surface defects, surface undulation etc. In no case such defects shall exceed 200 mm in any direction for individual spots or the continued area of such defects shall not exceed 0.2% of the entire area of related surface. Any variation beyond this limit shall be considered as a substandard work and shall be liable for rejection. The Engineer-in-Charge shall have the option to accept the so formed concrete at a reduced rate for defects exceeding this limit provided it is structurally adequate and due matching of defective patches is done by the contractor to the entire satisfaction of the Engineer-in-Charge.



Special care shall be taken to ensure that no stains are left on the formed concrete either from form work or exposed reinforcement bars. Such stains shall be removed by the contractor at no extra cost so as to match with adjoining concrete surfaces to the satisfaction or the Engineer-in-Charge. Shutter stripping solution/chemical of approved quality shall be used on shutter plates and use of burnt oil shall be avoided.

1.14 Protection of concrete below ground levelConcrete placed below the ground shall be protected from falling earth during and after placing. Concrete placed in ground containing deleterious substances shall be kept free from contact with such ground and with water draining there from during placing and for a period of seven days or as otherwise instructed thereafter. Approved means shall be taken to protect immature concrete from damage by debris, excessive loading, abrasion, vibrations, deleterious ground water, mixing with earth or other materials, and other influences that may impair the strength and durability of the concrete.

1.15 CONSTRUCTION JOINTS

Before the concrete is fully hardened, all latence shall be removed by scrubbing the wet surface with wire or bristle brushes. Care shall be taken to avoid dislodgement of particles of coarse aggregate. The surface shall then be thoroughly wetted, all free water removed and then coated with neat cement grout. Particular attention shall be given to corners and close spots.

Construction joints in all concrete work shall be made as directed by the Engineer-in-Charge. Where vertical joints are required, these shall be shuttered as directed and not allowed to take the natural slope of the concrete. The stop end at construction joint shall be made from special expanded wire mesh of two / three layers to facilitate the reinforcement to pass through. Before fresh concrete is placed against a vertical joint, the old concrete shall be chipped, cleaned and moistened.

When a horizontal construction joint is formed, provision shall be made for interlocking with the succeeding layer by the embedment of saturated wooden blocks or wooden strips beveled on four sides to facilitate their removal. Prior to the next pour the wooden pieces shall be loosened and removed in such a manner as to avoid injury to the concrete. After about 8 to 12 hours of concreting, contact surface shall be hacked with a mechanical chisel or by sand blasting, to expose the aggregate surface and remove laitance. Immediately thereafter clean the surface using compressed air to remove all the dirt. The surface shall then be compressed air cleaned to remove all dirt. Before applying fresh concrete, the contact surface shall be wetted for at least 6 hours. After the surface has dried, two coats of cement paint shall be applied uniformly using a brush over the old concrete just before placing the fresh concrete. The fresh concrete shall be placed immediately after applying the cement coats. The fresh concrete shall be thoroughly vibrated near the construction joint so that the mortar from the new concrete flows between the large aggregate and develop proper bond with old concrete. The construction joint shall ensure proper bond and leak proof joint.

Use of metal, rubber or plastic water stops is specified, this shall be cast into joints. Measures shall be taken by the Contractor to ensure that no displacement or



distortion of water stops takes place during placing of concrete. The construction joints shall ensure proper bond and leak proof joint.

1.16 Curing of concrete

Curing of concrete shall be complete and continuous using water that is free of harmful amounts of deleterious materials that may attack, stain or discolour the concrete. The water used for curing shall confirm to the requirements or clause 302.4 of IRC: 21- 2000.

Immediately after compaction and completion of concreting, the concrete shall be protected from evaporation of moisture by means of polyethylene sheets, wet hessian cloths or other material kept soaked by spraying water. As soon as the concrete has attained a degree or hardening sufficient to withstand surface damage, moist curing shall be implemented and maintained for a period of at least 14 days after casting.

The top surface of the concrete and other horizontal surfaces shall be cured by impounding water (confirming to the requirements of clause 302.4 of IRC: 21- 2000) in cement / mud mortar bunds. Steeply sloping and vertical formed surfaces shall be kept completely and continuously moist prior to and during the striking of formwork by applying water to the top surfaces and allowing it to pass down between the formwork and the concrete. After removal of form, moist curing to be done by wrapping hessian cloth, etc. and keeping it moist by suitable means.

1.17 GRADE OF CEMENT CONCRETE

Only design mix concrete shall be used in the works for various structural members. The grades of concrete for various components of work shall be as specified in the relevant item and/or drawing. In case of any discrepancy, the grade of concrete as specified in item shall prevail unless otherwise approved by engineer-in-charge. However, this discrepancy must be brought to the notice of engineer-in-charge by the contractor before start of said concrete work for final decision.

1.18 COVER BLOCK

The Contractor shall provide approved type of supports for maintaining the bars in position and ensuring required spacing and correct cover of concrete to the reinforcement as called for in the drawings. Cover blocks of required shape and size, M.S. chairs and spacer bars shall be used in order to ensure accurate positioning of reinforcement.

1.19 STEEL REINFORCEMENT FOR STRUCTURE

1.19.1 General

The reinforcement bars bent and fixed in position shall be free from rust or scales, chloride contamination and other corrosion products. Effective methods of cleaning will have to be used so that the steel is free from rust, scales and contamination. The decision of Engineer-in-Charge in this regard shall be final & binding.



1.19.2 Bending of Reinforcement

Bending of reinforcement shall be done as per bar bending schedule to be prepared and got approved by the contractor from Engineer-in-Charge or his authorised representative prior to commencement of work. The bar cutting and bending for 16mm and above diameters shall be done on bar cutting and bending machine only.

1.19.3 Placing of Reinforcement

Reinforcement left projecting from newly placed concrete shall be supported in such a way that there is no sag or risk of damage to the newly placed concrete. The projecting bars that are likely to be exposed for a long time shall be protected by a coat of neat cement wash. These shall be thoroughly cleaned and wire brushed before depositing fresh concrete around it. No reinforcement bar shall remain exposed or projecting out of the concrete surface. These shall be removed or treated in a manner as directed by Engineer-in-Charge. The unwanted projected reinforcement bars shall he cut below the finished surface and the cut end painted with epoxy paint. Thereafter the surface shall be repaired to match the colour, texture or pattern of adjoining concrete to the satisfaction of Engineer-in-Charge.

1.19.4 Bar Splices

The location of joints in continuous reinforcing bars, not shown in drawings, shall be submitted to the Engineer for acceptance. If nothing contrary has been specified, the number of bars to be joined in any cross section shall not exceed one-third of the total.

1.20 SHUTTERING, FORMWORK etc.

1.20.1 General

Steel shuttering shall only be used for concrete work to produce a smooth and uniform finish on all exposed surfaces. The entire responsibility of planning, designing, erection, dismantling, shifting and safety of false work lies with the contractor. Individual steel shuttering plates shall have a minimum size of O.9m x 1.5m (minimum area 1.35sq.m) except in the matching pieces, and smaller components. Formwork shall be made out of minimum 5 mm thick M.S. plates with stiffeners (thickness not less than 5mm) or as per design approved by Engineer-in- Charge.

1.20.2 Re-use of Forms

Before re-use, all forms shall be thoroughly scrapped, cleaned, joints and plates examined and when necessary/repaired and inside surface treated as specified herein before. Formwork shall not be used/re-used if declared unfit or unserviceable by the Engineer- in-charge. Nothing extra or any claim whatsoever shall be admissible on this account.



The contractor is to make good at his own expenses any injury to the concrete work and any damage caused by, or arising from the removal and striking of shutters and supports. Notwithstanding conditions and requirements mentioned in the foregoing paragraphs the shuttering should be such that all concrete work remains shutter finished as per pattern approved by the Engineer-in-charge.

1.20.3 Formed Surface and Finish

All members above ground or formation level shall have shutter finished surfaces. Utmost care shall be taken by the contractor in erection of formwork for components cast in stages. Location of construction Joints in between such stages shall be predecided and all such joints shall be treated in a manner approved by the Engineer-in-charge so as to match with the surrounding concrete without leaving any visual aberration or bad patches and/or bands. The contractor shall be deemed to have included the cost of such operation in his quoted rates and no claim whatsoever shall be entertained at a later date.

The formed finished concrete surfaces shall be free from honeycomb, blemishes, holes, surface defects, etc. In no case such defects shall exceed 200mm in any direction for individual spots or the continued area of such defects shall not exceed 0.2% of the entire area of related surface. Any variation beyond this limit shall be considered as a substandard work and shall be rejected.

Special care shall be taken to ensure that no stains are left on the formed concrete either from formwork or exposed reinforcement bars. Such stains shall be removed by the contractor at no extra cost so as to match with adjoining concrete surfaces to the satisfaction of tile Engineer-in-charge.

1.21 ROAD WORK

1.21.1 SUB-GRADE CONSTRUCTION

It shall be ensured prior to actual execution that the borrow area material to be used in the sub-grade satisfies the requirements of design CBR (not less than' 5%, under soaked condition). For the purposes of specifications, the top 500mm thick layer of filling in the embankment (just below the sand drainage layer) over the entire formation width and directly supporting the road pavement will be termed as 'subgrade'.

Sub-grade shall be compacted and finished to the design strength consistent with other physical requirements. The actual laboratory CBR values of constructed sub-grade shall be determined on remoulded samples. IRC: 37-1984 shall be referred to for details.
