Engineer in Charge than the corresponding standard quoted herein.

Testing

During the progress of construction sampling, preparation of test specimens, curing and testing of

concrete shall be conducted in accordance with IS 1199 and IS 516, to determine whether the

concrete being produced complies with the strength requirements as specified.

At least one slump test shall be carried out for every compressive strength test carried out, or as

directed by the Engineer. Six No. cubes shall be made for each cubic meter for portion thereof or

for each pour per grade of concrete. This number may be increased at the discretion of the

Engineer. Six specimens shall preferably be prepared from different batches, three being tested after

179


expense, all apparatus, labor and arrange for testing at a laboratory, approved by the Engineer in

Charge.

Acceptance of Concrete

The concrete tested in accordance with “Testing of Concrete” clause above, shall meet the criteria

for acceptance of concrete as per BIS 456. The strength of concrete shall be the average strength of

three specimens tested at 28 days and conform to strength requirements of different grades of

concrete. If the advance 7 days tests show crushing strengths that are too low, corrective measures

shall be taken at once, at the Engineer’s direction, without waiting for the results of the 28 days

tests.

Failure to meet Strength Requirements: -

In cases where concrete tested fails to meet the test requirements, the Engineer in Charge shall have

the right to require any one or all the following additional tests. The Contractor at his own expense

shall carry these out. The Engineer in Charge shall be the final authority for interpreting the results

and shall decide upon the acceptance or other wise.

Curing and load testing of the concrete member concerned represented by the test, which fail,

the concrete, relevant formwork, or reinforcement shall be made. The Contractor at his own

expenses shall make good, embedded fixtures and reinforcement of adjoining structures damaged

during dismantling well & extended curing of the structure of the concrete repaired by the specimen

& collecting and testing of a core specimen from the hardened concrete. The location number and

size of such specimen shall be taken as directed by the Engineer.

Any other test i.e. ultrasonic and /or rebound hammer tests to be decided by the Engineer, at the

Contractors own cost.

Water Retaining Structures: -

In addition to the tests of the concrete structure regarding “Failure to meet Strength Requirements”

referenced above, each water retaining structure shall also be tested for water tightness at “top

water level” as follows:

The structure shall be thoroughly cleaned and as far as practicable before any earth or other filling

is placed against the outside wall face, water retaining structures shall be filled with water at a

uniform rate of not greater than 2m in 24 hours. A period of 21 days shall be allowed for

stabilization, after which the water level shall be recorded by an approved method, at 24-hour

periods for a test period of 7 days. During the test period the total permissible drop, after allowing

180


for evaporation and rainfall, shall not exceed 1/500 of the average water depth of the full tank or

10mm, whichever is less.

In the case of structures whose external faces are exposed, such as elevated tanks, the test

requirements shall be deemed to be satisfied if the external faces show no signs of leakage and

remain apparently dry over a period of seven days, after allowing an initial seven days period for

absorption after filling.

In the case of structures whose external faces are submerged and are not accessible for inspection,

such as underground tanks, the tanks shall be filled with water and after filling; the level of the

surface of the water shall be recorded at subsequent intervals of 24 hours, for a period of seven

days. The total drop in level over the seven-day period shall be taken as an indication of the water

tightness of the structure. The Engineer shall decide on the actual permissible magnitude of this

drop in surface level, taking into account whether the tanks are open or closed and the

corresponding affect it has on evaporation losses. For many purposes however, an underground

tank whose top is covered may be deemed to be watertight if the total drop in the surface level over

a period of seven days does not exceed 40 mm.

If the structure does not satisfy the test requirements, and the daily drop in water level is greater

than that allowable, the period of test may be extended for a further seven days and if the specified

limit is then met, the structure may be considered as satisfactory.

If the test results are unsatisfactory, the Contractor shall ascertain the cause and make all necessary

repairs and repeat the water retaining structures test procedures, at his own cost. Should the re-test

result still be unsatisfactory after the repairs, the structure will be condemned and the contractor

will dismantle and reconstruct the structure, to the original specification, at his own cost.

Roofs: -

Concrete roofs of service reservoirs or buildings shall be watertight and shall, where practicable, be

tested on completion by water trenching to a minimum depth of 25 mm for a period of 24 hours.

Where it is impracticable, because of roof falls or otherwise, to contain a 25 mm depth of water, the

roof shall be thoroughly wetted by continuous hosing for a period of not less than 6 hours. In either

case, the roof shall be regarded as satisfactory if no leaks or damp patches show in the roof.

The roof covering shall be completed as soon as possible after satisfactory testing.

Specification of Road Works:

This part of the specification shall apply to all internal roads: -

a) Embankment: The fill shall be well compacted to utilize its full strength & o economize there by

on the overall thickness of pavement required. Top 50 cm portion of the roadway shall be well
