CLASSES OF CONCRETE :

Two classes of concrete are covered by this specifications.

a. ORDINARY GRADE CONCRETE :

1. The proportions for ordinary concrete are chosen arbitrarily as stated in Table I and the

batching of materials shall be done by volume. The cement shall be considered to occupy 35

litres per bag of 50 kg. All cement bags used in the work shall be weighed and their

quantity adjusted to 50 kg, before use at contractor‟s cost.

2. The mix proportions for each portion or the work shall be stated in the drawing and shall

be one of the proportions given in the Table I below. Each one of the mixes given in the

Table I shall give 28 days works cube strength indicated against it. The richer mix shall

be used at junctions where members of different proportions meet. Control test cubes

(15cm sides) as per IS: 516 shall be cast at the rate of 3 Nos. for every 30 cu.m or less,

concrete cast per day and tested at 28 days.

3. The water-cement ratio shall not be more than that indicated in the table I above. The cement

content in each nominal mix shown above may be increased suitably to overcome difficulties of

placement and compaction so that the water-cement ratio given above is not exceeded.

In the case of vibrated concrete, the limit of water-cement ratio given above may have to be

reduced to avoid segregation.

The above water requirements are based on the assumption that all aggregates are dry. When

moist or wet aggregates are used, water added to the batch shall be reduced suitably to

maintain the total water cement ratio as stated above. 4. Quantity of fine aggregate is based on the assumption that dry sand is used. When using moist

sand, suitable allowance shall be made for bulking so as to avoid under sanded mixes.

97


5. If the quality of materials used in the work do not give the strengths appropriate to

the mix proportions indicated in Table I above, then such concrete shall be designated

as belonging to the appropriate lower grade. Ordinary grade concrete proportioned for

a given designation as per Table I above shall not however be placed in a higher grade

on the ground that the test strengths are higher than the minimum specified. No

interpolation shall be permitted.

CONTROLLED CONCRETE :

1. All concrete used for structural applications shall be controlled grade concrete. The

concrete shall be designated by the works cube strength Kg/ cm2 at 28 days evaluated

as per clause (4) below. Thus, concrete designated as M200 shall mean concrete having

a cube strength of 200 Kg/cm2 at 28 days.

2. Mix proportions used for a particular designation of concrete shall be based on the results

of preliminary tests carried out on samples of materials proposed for use in the works.

Any of the recognized methods of mix design such as Read Note No.4 (H.M.S.O. London)

or any other approved method may be used in the design of trial mixes. Trial mixes

shall take into consideration the workability required at site for placing the concrete in

the structure. Preliminary test will have to be made if the source of the materials

changes or any changes in mix proportions are to be made in the course of construction.

3. PRELIMINARY TESTS : The cube strengths of concrete as observed during the preliminary tests

carried out under laboratory condition shall have a minimum value as mentioned in Table I. PP

23 of IS : 456- 1964.

4. WORKS CUBE TESTS : Test specimens for works cube tests shall be secured. Prepared and tested generally in accordance with IS: 516. Cubes shall preferably be cast near the point

of placing the concrete and shall be cured in a manner identical to the method used for

curing the structural member, the concrete of which they represent.

A minimum of 6 cubes shall be cast for each 3 Cmt or portion thereof, comprising of one

pour of concrete of one grade being placed. At least one half of the cubes prepared

shall be tested at 28 days in an approved laboratory at the contractor‟s cost. The

balance half may be tested at 7 days and after a suitable correlation between 7 days

and 28 days tests has been established at site, the 7 day test may be used as an

indication of trends in the quality control of concrete.

The criteria for evaluating the test results shall be as follows :

- Not more than one out of 5 consecutive cubes tested shall give a value less than the specified

strength and this reduced strength shall not be less than 90% of the specified strength and

- the average strength of the specimen tested shall not be less than the specified

strength.

98


5. All materials shall be batched by weight, except water which may be measured by volume

in graduated containers.

Cement shall be weighed separately. The accuracy of all weighing devices shall be maintained

within 1 % and the devices shall be checked periodically as directed by the Engineer. The weigh

batch machine shall be Heatley Gresham or of other approved make.

Cumulative batching of materials may be permitted provided the method of measurement given

the above specified accuracy.

All machines and methods used for batching shall be subject to the approval of the Engineer.

6. The quantity of the mixing water shall be controlled throughout the works. At least one

determination of moisture content shall be made every day, preferably just before

commencement of the concreting work. Determination of moisture content of the

aggregate shall follow the procedure given in IS: 2386 (Part III) “Methods of Test of

Aggregate for Concrete; Part III Specific Gravity, Density, Voids, Absorption and Bulking.

7. At least one test for workability shall be done for every 30 Cft of concrete cast per pour or

per day, whichever is less.

8. All controlled grade concrete shall be compacted by mechanical vibration.

BATCHING & MIXING :

a. The aggregate shall be handled from the stock piles to the batching plant/ mixer in

such a manner as to prevent segregation. Aggregate shall not get mixed with earth or

any foreign matter during the handling process.

b. The approved type of weigh batcher shall be used for proportioning the ingredients at

wherever necessary to avoid thick joints of mortar. In case any stone already set in mortar is

disturbed or the joint broken the stone shall be taken out without disturbing the adjoining stones

and joints and the stones reset in fresh mortar. Attempts must never be made to slide one stone

over another already laid.

Watering :All masonry shall be initially protected from sun, rain, etc., by wet hessian or strawtill

setting and thereafter kept continuously wet for 14 days from the date of laying, unless other

length of period is ordered in the special provisions. Watering shall be done carefully in the

beginning through a hose so as to wash the mortar out of the joints. On Sundays, holidays, at the close of day‟s work and other periods of cessation of work, the masonry is to be kept continuously wet for the specified period of curing and laborers are to be employed for

the purpose. Should the contractor fail to water the work to the satisfaction of the Architect, the

latter may order the masonry to be dismantled at the contractors cost.

Bad work : Should the mortar perish, i.e., become dry, white or powdery through neglect of watering or if the

masonry shows hollow joints or non-adherence of mortar to the stones or if the work does not

conform to plans and these specifications, the work must be pulled down and rebuilt at the contractors expense without any delay after the order of the Architects to do so.

Final Finish : All masonry shall be washed down on completion and all stains and adhering mortar removed

from the face as the scaffolding is being lowered and removed.

Wet foundations: In wet foundations, or other situations where water is met with, the work space shall be kept free

of water by the contractor while the masonry is in progress and until the Engineer considers the

mortar has sufficiently set. Dewatering shall be carried out in such a way as not to injure the

concrete or masonry in any way. Dewatering shall also be done when required for taking checking

measurements, passing foundation etc., Dewatering will be included in the rate of masonry.
