6.3 STRENGTH REQUIREMENT OF CONCRETE:
The compressive strength requirements for the various mixes by concrete shall be as follows:
Type of Minimum Compressive strength in kg/cm²
concrete. Of 150 mm cubes
Note: Seven days test results give an early indication of a possible weak concrete.
days compressive strength specified in table shall alone be the criteria for
acceptance or rejection of the concrete. Where the strength of a concrete mix falls
short of the requirement mentioned in the table, such concrete shall be classified
for all purposes, as the concrete mix in above table which corresponds to that
6.4 ACCEPTANCE CRITERIA:
(a) The average strength of the group of cube cast for each day shall not be less than the
specified cube strength for the work. About 20% of the cube cast for each day may have
values less than the specified strength provided the lowest value is not less than 85% of the
specified strength.
(b) In case the concrete does not confirm to the acceptance criteria for strength as specified
above, the Engineer-in-Charge reserves the right to reject the work or accept the same at a
reduced rate derived from tender rate and as approved by him.
6.5 PROPORTIONING CONCRETE:
a. The mix proportion shall be selected to ensure the workability of the fresh concrete and when
concrete is hardened, it shall have the required strength, durability and surface finish.
b. Except where it can be shown to the satisfaction of the Engineer-in-charge that supply of
properly graded aggregate of uniform quality can be maintained till the completion of the
work, grading of aggregate shall be controlled by obtaining the coarse aggregate in different
sizes and blending them in the right proportions as required. Different sizes, however, shall
be stacked in separate stock piles. Required quantity of material shall be stock-piled several
hours, preferably a day, before use. Grading of coarse and fine aggregates shall be checked as
frequently as possible. Frequency for a given job being determined by the Engineer-in-Charge

in the preliminary tests. In proportioning concrete, the quantity of both cement and aggregate
shall be determined by weight, water shall either be measured by volume in calibrated tank or
weighed. All measuring equipment shall be maintained in a clean and serviceable condition.
Their accuracy shall be periodically checked.
c. It is most important to keep the specified water cement ratio constant. To this end, moisture
content in both fine and coarse aggregates shall be determined by the Engineer-in-charge. The
amount of mixing water shall then be adjusted to compensate for any variations observed in
the moisture content. For the determination of moisture content in the aggregate IS: 2386 -
1977 (Part - III) shall be referred to. Suitable adjustments shall also be made in the weight of
aggregate to allow for variations in weight of aggregates due to variations in their moisture
d. The cement level for various grades of controlled concrete shall be considered as under for
the purpose of working out the rates to be quoted in BOQ.
Sr. No. Grade of concrete Minimum Cement level Remarks

3 M-20 360 For Lining / RCC Work
4 M-20 330 For Lining / RCC Work
e. Actual cement level required for the aggregates to be used shall have to be determined by
laboratory tests. The mix proportions shall be selected to ensure that the workability of the
fresh concrete is suitable for the conditions of handling and placing, so that after compaction
it surrounds all reinforcements and completely fills the formwork. When concrete is hardened,
it shall have the required strength, durability and surface finish.
f. A mix shall be designed to produce the grade of concrete having the required workability and
characteristic strength not less than that stipulated in table under Para 3.5 of tender
specification. However, due to change in design mix or due to change in environmental
exposure condition (Clause 8.2.2 of IS: 456-2000), if it becomes obligatory to use more
cement per cubic meter of concrete, the Contractor shall use more cement without claiming
any extra cost for handling of extra cement. The contractor has to utilize minimum cement
content as described above under the 3.7 (d) for respective items for durability purpose even
if the cement level derived may be less in mix design for any item. Design mix and actual
cement level required shall be communicated to the Contractor in writing by the Engineer-in-
charge. No additional claim regarding change in proportion of coarse aggregate and sand shall
be entertained.
g. The quantity of water shall be just sufficient to produce a dense concrete of required
workability and strength for the job. An accurate and strict control shall be kept on the quantity
h. In the case of reinforced concrete work, workability shall be such that the concrete surrounds
and properly grips all reinforcement. The degree of consistency, which shall depend upon the
nature of work and methods of vibration of concrete, shall be determined by regular slump

into the drum of the mechanical mixer while it is continuously running. After about half a
minute of dry mixing, measured quantity of water required for each batch of concrete mix
shall be added gradually and mixing continued for another one and a half minute.
(b) Mixing shall be continued till materials are uniformly distributed and uniform colour of the
entire mass is obtained and each individual particles of the coarse aggregate shows complete
coating of mortar containing its proportionate amount of cement. In no case shall the mixing
be done for less than 2 minutes after all ingredients have been put into the mixer.
(c) When hand mixing is permitted by the Engineer-in-Charge for small jobs or for certain other
reasons in the interest of the work, it shall be done on a smooth watertight platform large enough
to allow efficient turning over the ingredients of concrete before and after adding water. Mixing
platform shall be so arranged that no foreign material gets mixed with concrete. The bags shall
be placed in a uniform layer on top of the measured quantity of fine and coarse aggregates,
which shall also be spread in a layer of uniform thickness on the mixing platform. Dry coarse
and fine aggregate and cement shall than be mixed thoroughly by turning over to get a mixture
of uniform colour. Specified quantity of water shall then be added gradually through a rose can
and the mass turned over till a mix of required consistency and colour is obtained. In hand
mixing, quantity of cement shall be increased by 10 percent above that specified for which no
extra payment would be made by the Nigam.

for any variation in the moisture content or grading of the aggregates as they enter the mixer.
Addition of water to compensate the stiffening of the concrete resulting from over mixing or
objectionable drying before placing shall not be permitted. Uniformity in concrete consistency
from batch to batch shall be required. Where concrete is laid from the bottom to the top of the
slope the consistency shall be such that the concrete will just stay in place on the slope. A
slump of 60 to 70 mm shall generally be allowed. For heavier longitudinally operating slip
from machines, a slump of 50 mm shall be permitted. To have a close control of consistency
and workability of the concrete, the slump of concrete shall not vary more than 20 mm from
the one specified as above.
6.6.4 WATER CEMENT RATIO:
(a) Water – cement ratio will be regulated by the requirements of workability strength and
durability. The proportion of water to cement in any concrete shall be such as to produce a
mixture, which can work readily in to corners and angles of the forms without segregation.
Water – cement ratio shall be adjusted as 0.5 to 0.6 as per grade or as directed. Workability
shall be maintained for easy lacing of concrete.
6.6.5 Transporting Concrete

inspected and then so directed by the Engineer – in-Charge. All absorptive surfaces against
which concrete is to be laid shall be moistened adequately so that moisture shall not be
withdrawn from freshly placed concrete. The surfaces, however, shall be free from standing
(c) Concrete shall be deposited in all cases as neatly as practicable directly and shall not be caused
to flow in a manner to permit segregation. Excessive separation of the coarse aggregate caused
by allowing the concrete to fall freely from too great a height or at too great an angle from the
vertical shall not be permitted and where such separation would otherwise occur the Contractor
shall provide suitable means to convey the concrete without allowing such separation.
(d) Compaction of concrete shall whenever practicable be carried out by the use of vibrators.
During placing and until curing is complete, the concrete shall be protected against the harmful
effect of exposure to sunlight, wind and rain as directed.
6.6.7 Finishing
(a) All exposed concrete surfaces shall be cleaned of impurities, lumps of mortar or grout and
unsightly stains. The finished surface shall be even, smooth and free from pockets and
equivalent to that obtainable by effective use of a long handle steel towel. Where the surface

ready for installing before actual concreting begins. Detailed plans, methods and procedures
whereby the various phase of curing and protection shall be firmly established, shall be settled
and got approved in writing from the Engineer-in- Charge sufficiently in advance of the actual
concreting. The equipment and method proposed to be utilized shall provide for adequate control
and avoid interruption or damage to the work of other agencies. The curing of concrete shall be
either Membrane curing or water curing.
(ii) Membrane Curing
These specifications cover curing of concrete using membrane forming compound to retard the
loss of water during the early hardening period and to reduce the temperature rise in concrete
exposed to radiation from the sun. This compound shall be suitable for use as curing media for
fresh concrete and for further curing of concrete after removal of forms or after initial moist
(iii) Water curing
Uniformed top surface of invert of the canal structure shall be kept continuously moist by
covering it completely with wet jute-begs as soon as the concrete has hardened sufficiently say,
4 to 6 hours after concrete placement. The jute-begs shall be kept continuously wet by spraying
water for at least 12 hours. Thereafter curing by ponding shall be resorted to. Concrete cured
with water shall be kept wet by ponding for at least 14 days. Water lost by evaporation shall be
replenished periodically to keep the surface continuously (not periodically) submerged under
water. When the curing of concrete in the canal bed is not found satisfactory the Engineer-in-
Charge may ask the Contractor to resort to membrane curing without any extra cost to SSNNL.
