2.1 The concrete mix shall be designed by preliminary tests, the proportioning of cement and
aggregates shall be done by weight and necessary precautions shall be taken in the production to
ensure that the required work cube strength is attained and maintained. The controlled concrete
shall be in grade of M-200 with prefix controlled added to it. The letter ‘M’ refers to mix and numbers
specify 28 days works cube compressive strength of 150mm cubes of the mix expressed in Kg/
2.2 The proportion of cement, sand and coarse aggregates shall be determined by weight. The
weigh batching machine shall be used for maintaining proper control over the proportion of
aggregates as per mix design.
The strength requirements of different grades of concrete shall be as under :
Grade of concrete Compressive strength of 15 cms. cubes in Kg / Cm2 at
days, conducted in accordance with IS 516 –
Preliminary test (min) Work test (min)
In all cases, the 28 days compressive strength specified in above table be the criteria for
acceptance or rejection of the concrete. Where the strength of a concrete mix as indicated by
tests, lies in between the strength of any two grades specified in the above table, such concrete
shall be classified in for all purposes as concrete belonging to the lower of the two grades between
which its strength lies.
2.3 Admixture may be used in concrete only with approval of Engineer – in – Charge based upon
the evidence that with the passage of time neither the compressive strength of concrete is reduced
nor are other requisite qualities of concrete and steel impaired by the use of such admixture.
3.0 Workmanship
3.1 The proportions for ingredients chosen shall be such that concrete has adequate workability
for conditions prevailing on the work in question and can be properly compacted with means
available except where it can be shown to the satisfaction of the Engineer – in – Charge, that the
supply of properly graded aggregate of uniform quality can be maintained till the completion of
work. Grading of aggregate shall be controlled by obtaining the coarse aggregates, in different
sizes and being in them in the right proportions as required. Aggregate of different sizes shall be
stocked in separate stock piles. The required quantity of material shall be stock piled several hours,
preferably a day before use. The grading of coarse and fine aggregate shall be checked as
frequently as possible, the frequency for a given job being determined by the Engineer – in –
Charge to ensure that the suppliers are maintaining the uniform grading as approved for samples
used in the preliminary tests.
3.2 In proportioning concrete, the quantity of both cement and aggregate shall be determined by
weight. Where the weight of cement is determined by accepting the maker’s weight per bag a
reasonable number of bags shall be weighed separately to check the net weight. Where the
cement is weighed from bulk stocks at site and not by bags, it shall be weighed separately from
the aggregates. Water shall either be measured by volume in calibrated tanks or weighed. All
measuring equipments shall be maintained in clean, and serviceable condition. Their accuracy
shall be periodically checked.
3.3 It is most important to keep the specified water cement ratio constant and at its correct value.
To this end, moisture content in both fine and coarse aggregates shall be determined by the
Engineer – in – Charge, according to the weather conditions. The amount of mixing water shall
then be adjusted to compensate for variations in the moisture content. For the determination of
moisture content in the aggregates, IS 2389 (Part III) shall be referred to. Suitable adjustments
shall also be made in the weights of coarse aggregates due to variation in the moisture content.
Minimum quantity of cement to be used in concrete shall not be less than 320 Kg / Cmt.
3.4.1 For all work, concrete shall be mixed in a mechanical mixer which along with other
accessories shall be kept in first class working condition and so maintained throughout the
construction. Measured quantity of aggregate, sand, cement required for each batch shall be
poured 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 half a 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 be done for less than two minutes
after all ingredients have been put into the mixer.
3.4.2 Mixers which have 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 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
3.5 Consistency
3.5.1 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 IS 1199 –
The slump of 10 mm to 25 mm shall be adopted when vibrators are used and 80 mm when vibrators
3.6.1 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 reliever the contractor of his
