overcome the difficulties of placement and compaction so that the water-cement-ratio specified in the
Table is not exceeded.
2.4. Workability of the concrete shall be controlled by maintaining a water-cement-ratio that is bound to give a
concrete mix which is just sufficiently wet to be placed and compacted without difficulty with the means
available.
2.5. The maximum size of coarse aggregate shall be as large as possible with in the limits specified but in no
case greater than one fourth of the minimum thickness of the member, provided that the concrete can be
placed without difficulty so as to surround all reinforcement thoroughly and to fill corners of the form.
2.6. For reinforced concrete work, coarse aggregate having a nominal size of 20 mm. are generally considered
satisfactory.
2.7. For heavily reinforced concrete members as in the case of ribs of main beams, the nominal maximum size
of coarse aggregate should usually be restricted to 5 mm. less than the minimum clear distance between
the main bars, or 5 mm. less than the minimum cover to the reinforcement whichever is smaller.
2.8. Where the reinforcement is widely spaced as in solid slabs, limitations of size of the aggregate may not be
important and the nominal maximum size may sometimes be as great as or greater than the minimum
cover.
2.9. 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 admixtures.
2.10. The form work shall conform to the shape lines and dimension as shown on the plans and be so

(ii) Spanning over 6 m. 21 days.
2.13. Procedure when removing the form work: 2.4.1. All form work shall be removed without such
shock or vibrations as would damage the reinforced concrete surface. Before the soffit 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.
2.14. Centering:
2.14.1. The centering to be provided shall be got approved. It shall be sufficiently strong to ensure absolute
safely of the form work and concrete work before, during and after pouring concrete. Watch should be
kept to see that behavior of centering and form work is satisfactory during concreting. Erection should also
be such that it would allow removal of forms in proper sequence without damaging either the concrete or
the forms to be removed.
2.14.2.The props of centering shall be provided on firm foundation or base of sufficient strength to carry the
loads without any settlement.
2.14.3.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 the work, injury to life and damage to property.
2.15. Scaffolding:
2.15.1.All scaffolding, hoisting arrangements and ladders etc. required for the facilitating of concreting shall be
provided and removed on completion work by contractor at his own expense. The scaffolding, hoisting

columns and the like.
(c) Temporary opening in the forms for pouring concrete, if required, removing rubbish etc.
(d) Dressing with oil to prevent adhesion of concrete with shuttering, and
(e) Raking or circular cutting.
2.16. Re-Use:
2.16.1. Before-re-use, all forms shall be inspected by Engineer-in-charge and their suitability ascertained.
The forms shall be scarred, cleaned, and joints gone over, repaired where required. Inside surface shall be
retreated to prevent adhesion of concrete.
2.0 General:
2.1. The relevant specifications of item No. 5.4.1. of ordinary concrete shall be followed except that the
concrete mix shall be designed from 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 grades of M-100, M-
150, M-200, M-250, M-300, M-350, & M-400, with prefix controlled added to it. The letter ‘M’ refers to mix
and numbers specify 28 days works cube compressive strength of 150 mm. cubes of the mix expressed in
Kg./Cmt.
Page 3 of 88
2.2. The proportion of cement, sand and coarse aggregates shall be determined by weight the weight batch
machine shall be used for maintaining proper control over the proportion of aggregates as per mix design.

The strength requirements of different grade of concrete shall be as under:
Grade Of Concrete Compressive strength of 15 cms. Cubes in Kg./Cmt. At 28 days,
conducted in accordance with I.S. 516-1959.
Preliminary test Min. Work test Min.

M-200 260 200
M-250 320 250
M-300 380 300
M-350 440 350
M-400 500 400
In all cases, the 28 days compressive strength specified in above table above 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.
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 weighted separately to check the net weight. Where cement is weighted from bulk stocks
at site and not by bags, it shall be weighted 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, I.S. 2389
(Part-III) shall be referred to. Suitable adjustments shall also be made in the weights of aggregates due to
variation in their moisture content. Minimum quantity of cement to be used in concrete shall not be less
than 220 Kg./M 3 in plain concrete and not less than 250 Kg/M3 in reinforced concrete.
