A random sampling procedure shall be adopted to ensure that each concrete
batch shall have a reasonable chance of being tested that is the sampling should
be spread over the entire period of concreting and cover all mixing units.
3.12.3.2 Frequency
The minimum frequency of sampling of concrete of each grade shall be in
accordance with the following:
_
_
Quantity of Concrete in the Number of Samples

51 and above 4 plus one additional sample

Corrections/Omissions/Insertions – NIL AE EE
 PART ‘B’ - 133

for each additional 50 m3 or part

thereof
NOTE- At least one sample shall be taken from each Shift. Where concrete is produced at
continuous production unit, such as batch-mixed concrete plant, frequency of’ sampling may
be decided by Engineer-in-charge in such a manner so as to ensure that each concrete batch
shall have a reasonable chance of being tested.

3.12.4 Test Specimen

Three test specimens shall be made for each sample for testing at 28 days.
Additional samples may be required for various purposes such as to determine
the strength of concrete at 7 days or at the time of striking the formwork, or to
determine the duration of curing, or to check the testing error. Additional
samples may also be required for testing samples cured by accelerated methods
as described in IS 9103. The specimen shall be tested as described in IS 516.
3.12.5 Test Results of Sample
The test results of the sample shall be the average of the strength of three
specimens. The individual variation shall not be more than +/- 15 percent of the
average. If more, the test results of the sample are invalid. 90% of the total tests
shall be done at the laboratory established at site by the contractor and
remaining 10% in the laboratory as mentioned in para 3.1.5, or in any other
NABL accredited laboratory as directed by the SE cum PD, CPWD, Hindupur
3.12.6 ACCEPTANCE CRITERIA
3.12.6.1 Compressive Strength
The concrete shall be deemed to comply with the strength requirements when
both the following condition is met:
a) The mean strength determined from any group of four consecutive test
results complies with the appropriate limits in col 2 of Table given under
para 3.1.4 above.
b) Any individual test result complies with the appropriate limits in col 3 of
Table given under para 4.1.4 above.
3.12.6.2 Quantity of Concrete Represented by Strength Test Results
The quantity of concrete represented by a group of four consecutive test-results
shall include the batches from which the first and last samples were taken
together with all intervening batches.
Where the mean rate of sampling is not specified the maximum quantity of
concrete that four consecutive test results represent shall be limited to 60 m 3.
3.12.6.3 Concrete of each grade shall be assessed separately.

Corrections/Omissions/Insertions – NIL AE EE
 PART ‘B’ - 134

3.12.6.4 Concrete is liable to be rejected if it is porous or honey-combed, its placing has

been interrupted without providing a proper construction joint, the
reinforcement has been displaced beyond the tolerances specified, or
construction tolerances have not been met. However, the hardened concrete
may be accepted after carrying out suitable remedial measures to the
satisfaction of the Engineer-in-Charge.
3.12.7 Ultrasonic Pulse Velocity Method of Test for RCC
3.12.7.1 The underlying principle of assessing the quality of concrete is that
comparatively higher velocities are obtained when the quality of concrete in
terms of density, homogeneity and uniformly is good. The consistency of the
concrete as regards its general quality gets established. In case of poorer quality
lower velocities are obtained. If there are cracks, voids or flaws inside the
concrete which come in the way of transmission of pulse, lower velocities are
obtained.
3.12.7.2 The quality of concrete in terms of uniformity, incidence or absence of internal
flaws, cracks and segregation etc. indicative of the level of workmanship
employed, can thus be assessed using the guidance given in table below, which
have been evolved for characterizing the quality concrete in structure in term of
the ultrasonic pulse velocity.
Velocity criterion for Concrete Quality Grading.
Sl. Pulse velocity by Cross Concrete Quality Grading
No. Probing (km/sec)
1 Above 4.5 Excellent
2 4.5 to 3.5 Good
3 3.5 to 3.0 Medium
4 Below 3.0 Doubtful
Note: In Case of “doubtful” quality it may be necessary to carry further tests.

3.12.7.3 Pulse velocity method of test of concrete is to be conducted for CPWD works as
a routine test. The acceptance criteria as per the above table will be applicable
which is as per IS 13311 (part-1): 1992. From the above “Good” and “Excellent”
grading are acceptable and below these grading the concrete will not be
acceptable. The cost of testing shall be borne by the contractor.
3.12.7.4 All RCC Columns and 5% of the other of RCC members in each category i.e.
beam, column, slab and footing may be tested by UPV test method for
establishing quality of concrete. It is suggested that test be conducted on RCC
beam near joint with column, on RCC column near joint with beam, on RCC
footings and rafts. On RCC rafts a suitable grid can be worked out for
determining number of tests. In addition doubtful areas such as honeycombed

Corrections/Omissions/Insertions – NIL AE EE
 PART ‘B’ - 135

locations, locations, where continuous seepage is observed, construction joints

and visible loose pockets will also be tested.
3.12.7.5 The test results are to be examined in view of the above acceptance criteria “Good”
and “Excellent” and wherever concrete is found with less than required quality
as per acceptance criteria, repairs to concrete will be made. Honeycombed areas
and loose pockets will be repaired by grouting using Portland Cement
Mortar/Polymer Modifies Cement Mortar /Epoxy Mortar ,etc. after chipping
loose concrete in appropriate manner. In areas where concrete is found below
acceptance criteria and defects are not apparently visible on surface ,injecting
approved grout in appropriate proportion using epoxy grout /acrylic Polymer
modified cements slurry made with shrinkage compensating cement / plain
cement slurry etc will be resorted to for repairs.(refer relevant chapters from
CPWD Hand Book on Repairs and Rehabilitation of RCC Buildings).Repair to
concrete will be done till satisfactory results are obtained as per the acceptance
criteria by retesting of the repaired area. If satisfactory results are not obtained
dismantling and relaying of concrete will be done.
