(a) At the beginning of the work or as and when required SSNNL shall make test to

determine the mix proportion required to produce the strength specified with the

material to be used in the work. The necessary ingredients shall be provided to

SSNNL, All cost shall be borne by the contractor.

(b) The mix shall be designed using representative samples of approved coarse and fine

aggregates as well as cement and water to be made available by the contractor to the

SSNNL, to achieve the required workability, cohesiveness, strength and durability at

minimum level of cement. Mix design studies and tests will be carried out by the

contractor at his own cost in the SSNNL's approved laboratory.

(c) During the execution of the work if the source of any ingredient of the concrete changes

then the contractor shall inform the Engineer-In-Charge sufficiently in advance so as to

allow him to proportion a new mix design to attain the specified strength of concrete.

At that time the representative samples of approved ingredient shall be supplied by the

contractor to the Engineer-In-Charge without any extra cost.The details of mix-design

including the proportion of each separate size and grading of aggregates and actual

cement level required shall be declared to the contractor in writing by the Engineer-

(d) Volume batching based on weight & not on proportion with the written permission of

Engineer-in-charge may be allowed only where weigh batching is not practical and

provided accurate bulk densities of material to be actually used in concrete have

earlier been established. Allowance for bulking shall be made in accordance with

I.S.2386 (part-3). The mass volume relationship should be checked as frequently as

necessary, the frequency for the given job being determine by Engineer-in-charge to

ensure that the specified grading is maintained.

1.4.8 Nominal mix:

The proportions for nominal mix concrete shall conform to the table given below, as specified in IS

1.4.8.1 General:

The proportions of materials for nominal mix concrete shall be as above.

1.4.8.2 Batching

The quantities of the various materials of concrete including water, cement and aggregates,

shall be considered by weigh batching based on dry volume. In case of sand there is a bulkage

due to moisture as such this aspect shall be considered both for the volume of sand and also for

the quantum of water to be addedfor getting the required slump. In the case of fine aggregates, the

surface moisture shall be determined in accordance with method of table-10 of IS: 456-2000.

1.4.8.3 Proportion of concrete:

(a) Concrete mix shall be designed on the basis of preliminary tests. The

proportion of ingredients shall be such that concrete has adequate

workability for conditions prevailing on the works in question and can be

properly compacted with the means available.

(b) Except when it can be shown to the satisfaction of the Engineer-in-Charge that

supply of properly graded aggregated 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

stockpiles. Required quantity of material shall be stockpiled 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 to ensure that the suppliers are maintaining the uniform

grading as approved for samples used 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 noted 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 aggregates to allow

forvariations in weight of aggregates due to variations in their moisture content.

(d) 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 reinforcement and

completely fills the formwork. When concrete is hardened it shall have the

required strength, durability and surface finish.

(e) 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

as above. However, due to change in design mix if it becomes obligatory to

use more cement per cubic meter of concrete., the contractor shall do the same

without claiming any extra cost for handling of extra cement. In case of actual

use being less than the cement level specified in table hereinabove. For

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 the proportion of coarse aggregate and shall be entertained.

(f) 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 of water.

(g) In case of reinforced concrete work, workability shall be such that the concrete

surrounds and properly grips all reinforcement. The degrees of consistency, which

shall depend upon the nature of work and methods of vibration of concrete

shall be determine by regular slump tests. Following slumps shall be adopted

for different types of works.

Sr. Type of work

1. Berms, slabs and columns 25mm to 40mm

2. Thin R.C.C section with 60mm to 70mm

requirements for the various grades of controlled concrete shall be as given in Table below :

Grade of Concrete Minimum Compressive Strength in kg/cm2 of

(150 x 150 x 150 mm) cubes

Seven days test results give an early indication of a possible weak concrete. In all cases 28 days

compressive strength specified in table above shall alone be the criteria for acceptance or rejection

Where the strength of a concrete mix as indicated by tests lies in between the strength for the

two grades specified in Table, such concrete shall be classified for all purposes as the concrete

belonging to the lower of the two grades between which its strength lies.

1.5 Cast In-situ Concrete Work

The work shall conform to IS : 3873-1978. The concrete shall be of controlled grade with suitable

admixtures using well graded aggregate with maximum size of aggregate of 20 mm / 40 mm (as

applicable) Ordinary Portland cement shall be used for the different grade of concrete. However,

due to change in design mix, if it becomes obligatory to use leaner/richer mix, the contractor shall

comply without any extra cost.

1.5.2 Stacking and Mixing

(a) The various raw materials for making concrete shall be stacked in separate

compartment near batching and mixing plant. The stack piles shall be large enough to

last at least for a day's work.All ingredient viz. Cement, sand, aggregates,

bentonite, slurry, admixture etc. shall be mixed in motor driven large size mixture

mounted on elevated masonry or concrete platform sufficiently high to suit the site

condition. Necessary arrangement for continuous supply of raw materials and

delivery of concrete shall be made by the contractor at his own cost.
