Recommendations:

From the above 3 Trail Mixes it is concluded that the Trial Mix-I is fit for the concreting

purpose. So the Trial Mix-I can be adopted for the Building concreting work. The abstract of

the final Trial Mix-I is given separately.

The mix designed proportion of cement concrete (Mix-I) is based on the quality of the

ingredient materials such as water, cement, fine aggregate and coarse aggregatesreceived

in this laboratory. More over as strength of concrete of the said Mix is directlyrelated to the

strength of cement mentioned at A-1 (table- II), cement having the same strength must be

used while adopting the above Mix design of concrete. Aggregates are used in (S.S.D)

saturated surface dry condition in the above Mix-I

NB:

The above test reports are based on the sample received by our laboratory.

The test results relates only to the items tested.

The report shall not be reproduced except in full without the approval of the testing

laboratory.
