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

in a new batch. Unless otherwise agreed to by the Engineer in-charge the first batch of concrete from

the mixture shall contain only two thirds of normal quantity of coarse aggregate Mixing plant shall

be thoroughly cleaned before changing from one type of cement to another

3.3. Consistency:

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

3.4. Inspection:

3.4.1. 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.

3.4.2. 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

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.

3.5.2. 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

meter when internal vibrators are used and not exceeding 0.30 meter in all other cases.

3.5.3. 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

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

3.5.4. 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 after the initial set, and shall be kept

continuously wet for a period of not less than 14 days from the date of placement. Masonry work over

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

Quantity of concrete in the No of samples Quantity of concrete in the No of samples

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

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

reveals a poor quality of concrete and in other special cases.

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

strength of 150 K/g Cm 2 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.
