works shall be subjected to quality control tests, as describe

hereinafter, the testing frequencies set forth are the desirab

15



minimum and the Engineer shall have the full authority to carryou

additional tests as frequently as he may deem necessary to satisf

himself that the materials and works comply with the appropriat

specifications. However, the number of tests recommended in tab

900-3 and 900-4 may be reduced at the discretion of the Enginee

if it is felt that consistency in the quality of materials can still b

maintained with the reduced number of tests.

Test procedures for the various quality control tests are indicated

th ti ti f th ifi ti f t i t

a)Sand content (IS:2720 (part -4) : 2 tests per 3000 cubic meters o

soil.

b)Plasticity Test (IS :2720) (part -5) : Each type to be tested 2 test

per 3000 cubic meters of soil.

c)Density Test (IS:2720 (PART-6) : Each soil type to be tested, 2 test

per 3000 cubic meters of soil.

d)Deleterious content test (IS 2720 (part-2) : One test for every cub

meters of soil.

e)CBR test on materials to be incorporated in the sub-grade or soak

un- soaked samples (IS 2720 (part -16): One CBR test for every 300

cubic meter at least or close as and when required by the Engineer.

is not less than the specified density plus:

However, for earth work in shoulders (earthen) and in the su

grade, at least one density measurement shall be taken for ever

500 square meters for the compacted area provided further tha

the number of tests in each set of measurements shall be at lea

10. In other respects, the control shall be similar to that describe

earlier.

Unless otherwise specified the rates for all RCC will be exclusive

Canopies and Platforms will be paid separately. Reinforcements w

be paid for separately.

Unless otherwise stated, for all RCC work the size of cours

aggregate will be 20mm and down size.

any trace of salt shall be rejected.

The fine aggregate for concrete shall be graded within limits a

specified in IS:383 and the fineness modules shall range betwee

2.60 to 3.20. The fine aggregate shall be stacked carefully on

clean hard dry surface so that it will not get mixed up wit

E) MIXING OF CONCRETE:

1) MACHINE MIXED:

Aggregates shall be accurately measured out in boxes and mixe

dry along with required cement. Water shall then be added in measure

quantity and mixing shall be continued until there is uniform distributio

of the materials and the mass is uniform in colour and consistency but

no case shall the mixing be done for less than 2 minutes only hoppe

loading mixer shall be used.

2. HAND MIXING:

If difficulty be experienced in placing the concrete of specified mix an

approved consistency between and below reinforcement bars, in th

bottom of beams and similar situations, the concrete shall have improve

16



workability by increasing the proportion of water and correspondin

additional quantity of cement and using aggregates of smaller size tha

specified as directed by Engineers for which no extra be paid.

Mixes with dried aggregates, or when so instructed by test of laborator

made test cubes under the direction of Engineers Consistency may b

measured by slump test using a standard cone or the Engineers ma

direct the use of any other means of testing the consistency.

Method of placing shall be such as to preclude segregation and as far a

practicable the placing shall be continuous.

Special care shall be taken in accordance with IS:456 while layin

16



concrete under extreme weather. Concrete, during the operation

placing shall be thoroughly worked around the reinforcements, embedde

fixtures, shaded against corners of the formwork by punning, rodding, o

by any other approved means and thoroughly compacted by mechanic

vibrators, The umber and type of vibrator to be used shall be subject

the approval of the Architects, and in general immersion type vibrato

shall be used.

Consolidation by using immersion vibrator will be in accordance with I

TRANSPORTING:

Concrete shall be conveyed from the place of mixing to the place of fin

deposit as rapidly as practicable by methods which will preve

segregation or loss of any of the ingredients. If segregation does occ

during transport the concrete shall be remixed before being place

Normally not more than 30 minutes small lapse between mixing an

consolidation in position.

CURING:

All cement concrete after laying shall be protected from damages, till

sets and shall be curved thereafter for not less than 10 days for pla

t k d t l th 21 d f i f d t t

harden excessively the surface shall be chipped over its whole surface to

depth of at least 10mm and thereafter thoroughly washed. Before fres

concrete is added on the construction joints, the surface of the o

conc ete shall be tho o ghl etted and co e ed ith a thin la e

16



concrete shall be thoroughly wetted and covered with a thin layer

cement mortar 1:2.

VERTICAL JOINTS:

At the end of any day’s work or run of concrete, the concrete shall b

finished of against temporary shutter stop which shall be vertical an

securely fixed. This shutter stop shall be removed as soon as th

weather permits.
