batch of concrete mix shall be added gradually and mixing continued for another one and

a half minute Mixing shall be continued till materials are uniformly distributed and uniform

colour of the entire mass is obtained and each individual particle of the coarse aggregate

shows complete coating of mortar containing its proportionate amount of cement. In no

case shall the mixing he done for less than 2 minutes after-oil ingredients have been put

into the mixer.

3.2.2. When hand mixing is permitted by the Engineer-in-charge for small jobs or for certain

other reasons, it shall be done on the smooth watertight platform large enough to allow

efficient tuning over the ingredients of concrete before and after adding water Mixing

platform shall be so arranged that no foreign malarial gets mixed with concrete nor does

the mixing water flow out. Cement in required number of bags shall be spread in n layer

of uniform thickness on the mixing platform. Dry coarse and fine aggregate and cement

shall then be mixed thoroughly be turning over to get a mixture to uniform colour.

Specified quantity water shall then be added gradually through a rose can and the mass

turned over till a mix of required consistency is obtained. In hand mixing quantity of

cement shall be increased by 10 percent above that specified.

3.2.3. Mixers which haw been out of use for more than 30 minutes shall be thoroughly cleaned

before putting in a new batch. Unless otherwise agreed to by the Engineer in-charge the

5.0 Procedure when removing the form work :

5.1. All form work shall be removed without such shock or vibrations as would damage the

reinforced concrete surface. Before the soffits form work and struts are removed, the

soffits and the concrete surface shall be exposed where necessary in order to ascertain

that the concrete has sufficiently hardened.

6.1. The centering to be provided shall be got approved. It shall be sufficiently strong to

ensure absolute safety of the form work and concrete work before, during and after

pouring concrete. Watch should be kept to see that behavior or centering and form work

is satisfactory during concreting. Erection should also he such that it would allow removal

of forms in proper sequence without damaging either the concrete or the forms to be

6.2. The props of centering shall be provided on firm foundation or base of sufficient strength

to carry the loads without any settlement.

6.3. The centering and form work shall, be inspected and approved by the Engineer-in-charge

before concreting. But this will not relieve the contractor of his responsibility for strength,

adequacy and safety of form work and centering. If there is a failure of form work or

centering, contractor shall be responsible for the damages to property.

7.0 Scaffolding:

7.1. All scaffolding, hoisting arrangements and ladders etc. required for the facilitating of

conceding shall be provided and removed on completion of work by contractor at his own

expense. The scaffolding, hoisting arrangements and ladders etc. shall be strong enough

to with sand all live, dead and impact loads expected to act and shall be subject to the

approval of the Engineer-in-charge. However contractor shall be solely responsible for the

safety of the scaffolding, hoisting arrangement, ladders, work and workman etc.

7.2. The scaffolding, hoisting arrangements and ladder shall allow easy approach to the work

spot and afford easy inspection.

7.3. The rate is applicable to all condition of working and height up to 4 mts. The rate shall

include the cost of materials and labour for various operations involved such as :

(a) Splayed edges, notching, allowance for overlaps and passing at angles, battens

centering, shuttering propping, bolting, wedging easing, striking and removal.

(b) Filleting to form stop chamfered edges or splayed external angles not exceeding

20 mm: width to beams, columns and the like.

(c) Temporary openings in the forms for pouring concrete, if required removing

(d) Dressing with oil to prevent adhesion of concrete with shuttering and.

(e) Raking or circular cutting.

8.1. Before re-use, all from shall be inspected by Engineer-in-charge and their suitability

ascertained. The forms shall be scarred, cleaned and joints are gone over, repaired

where required. Inside surface shall be retreated to prevent adhesion of concrete.

9.0. Consistency:

File : Specification_Sir J High School

9.1. The degree of consistency which shall depend upon the nature of the work and methods

of vibration of concrete shall be determined by regular slump tests in accordance with I.S.

1199-193. The skimp of 10 mm. to 25 mm shall be adopted when vibrators are used and

80 mm. when vibrators are not used.

9.2. Inspection:

9.2.1. Contractor shall give the Engineer-in-charge due notice before placing any concrete in

the forms to permit him to inspect and accept the false work and forms as to their

strength, alignment and general fitness but such inspection shall not relieve the contractor

of his responsibility for the safely of men machinery materials and for results obtained

immediately before concreting all forms shall be thoroughly cleaned.

9.2.2. Centering design and its erection shall be got approved from the engineer-in-charge. One

carpenter with helper shall invariably be kept present throughout the period of concreting.

Movement of labour and other persons shall be totally prohibited for reinforcement laid in

position. For access to different parts suitable mobile platforms shall be provided so that

steel reinforcement in position is not disturbed. For ensuring proper cover, mortar blocks

of suitable size shall be cast and tied to the reinforcement. Timber kapachi or metal

pieces shall not be used for this purpose.

9.3. Transporting and laying:

9.3.1. The method of transporting and placing concrete shall be as approved. Concrete shall be

so transported and placed that no contamination, segregation or loss of its constituent

material takes place. All from work shall be cleaned and made free from standing water

dust, show or ice immediately before placing of concrete. No concrete shall be placed in

any part of the structure until the approval of the engineer-in-charge has been obtained.

9.3.2. Concreting shall proceed continuously over the area between construction joints. Fresh

concrete proper contraction joint is formed. Concrete shall be compacted in its final

position within 30 minutes of its discharge from the mixer. 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 0.45 meter when internal vibrators are used and not

exceeding 0.30 meter in all other cases.

9.3.3. Unless otherwise agreed to by the Engineer-in-charge concrete shall be dropped in to

place from a height exceeding 2 meters. When trucking or chutes are used they shall be

kept close and used in such a way as to avoid segregation. 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. This 13 mm. layer of mortar shall

be freshly mixed and placed immediately before placing of new concrete. Where concrete

has not fully hardened, all lateness shall be removed by scrubbing the wet surface with

wire or bristle brushes, care being taken to avoid dislodgement of any particles of coarse

aggregate. The surface shall then be thoroughly wetted, all free water removed and then

coated with neat cement grout. The first layer of concrete to be placed on this surface

shall not exceed 150 mm. in thickness and shall be well rammed against old work,

particular attention being given to corners and close spots.

9.3.4. All concrete shall be compacted to produce a dense homogeneous mass with the

assistance of vibrators, unless otherwise permitted by the Engineer-in-charge for

exceptional cases, such as concreting under water, where vibrators cannot be used.

Sufficient vibrators in serviceable condition shall be kept at site so that spare equipment is

always available in the even of breakdowns. Concrete shall be judged to be compacted

when the mortar fills the spaces between the coarse aggregate and begins to cream up to

form an even surface. Compaction shall be completed before the initial setting stats i.e.

within 30 minutes of addition of water to dry mixture. During compaction, it shall be

observed that needle vibrators are not applied on reinforcement which is likely to destroy

the bond between concrete and reinforcement.

Immediately after compaction, concrete weather including rain, running water, shocks,

vibration, traffic, rapid temperature charges, frost and drying out process. It shall be

covered with wet sacking has Sian or other similar absorbent material approved, soon

File : Specification_Sir J High School

after the initial set, and shall be kept continuously wet for a period of not less than

days from the date of placement. Masonry work over foundation concrete may be started

after 48 hours of its laying but curing of concrete shall be continued for a minimum period

9.5. Sampling and testing of concrete:

9.5.1. Samples from fresh concrete shall betaken as per I.S. 1199-1959 and cubes shall be

made, cured and tested at 7 days of 28 days as per requirements in accordance with I.S.

526-1959. A random sampling 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 mixing units. The minimum frequency of

sampling of concrete of each grade shall be in accordance with following :

Quantity of concrete No of samples Quantity of concrete No of samples

in the work in the works

51 and above 4± one additional for each additional 50 mm. or part

Note : At least one simple shall be taken from each shift, Ten test specimens shall be made from

each sample, five for testing at 7 days and the remaining five at 28 days. The samples of

concrete shall be taken on each day of 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

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

cube strength of 150 K/g 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 then the minimum specified.

9.6. Stripping :

9.6.1. The Engineer-in-charge shall be informed in advance by the contractor of hr> intention to

strike the form work. While fixing the time of removal of form work, due consideration shall

be given to local conditions, character of the structure, the weather and other conditions

that influence the setting of concrete and of the materials used in the mix. In normal

circumstances (generally where temperatures are above 20.C) and where ordinary

concrete is used, forms may be struck after expire or periods specified in item No.9.1 (A)

for respective item of form work.

9.6.2. All form work shall be removed without causing any shock or vibration as would damage

the concrete. Before the soft and struts are removed, the concrete surface shall be

gradually exposed, where necessary in order to ascertain that concrete has sufficiently

hardened. Centering shall be gradually and uniformly lowered in such a manner as to

permit the concrete to take stresses due to its own weight uniformly and gradually. Where

internal metal tiles are permitted, they or their removable parts shall be extracted without

causing any damage to the concrete and remaining holes filled with mortar. No

permanently embedded metal part shall have less than 25 mm. cover to the finished

concrete surface. Where it is intended to re-use the form work, it shall be cleaned and

made good to the satisfaction of the Engineer-in-charge. After removal of form work and

shutting, the Executive Engineer shall inspect the work and satisfy by random checks that

concrete produced is of good quality.

9.6.3. Immediately after the removal of forms, all exposed bolts etc. passing through the cement

concrete member and used for stuttering or any other purpose shall be cut inside the

cement concrete member to a depth of at least 25 m. below the surface of the concrete

and the resulting holes be filled by cement mortar, all fins, caused by form joints, all

cavities produced by the removal of form tiles and all other holes and depressions,

File : Specification_Sir J High School

honeycomb spots, broken edges or comers and other defects, shall be thoroughly

cleaned", saturated with water and carefully pointed an rendered true with mortar of

cement and fine aggregate mixed in proportions used in the grade of concrete that is

being furnished and of as dry consistency as is possible to use. Considerable pressure

shall be applied in filling and pointing to ensure through filling in all voids. Surface which

are pointed shall be kept moist for a period of 24 hours. If rock pockets/honeycombs in

the opinion of the Engineer-in-charge are of such an extent or character as to effect the

strength of the structure materially or to endanger the life of the steel reinforcement, he

may declare the concrete defective and require the removal and replacement of the

portions of structure affected.

10.0. Mode of Measurement & Payment
