Sample Description: - Mix Design M-30

Protocol IS:10262, IS:456 &SP23 Guide line The method of concrete mix design consists of selection of optimum proportion of water, cement, fine

/coarse aggregate & admixture to produce concrete of specified properties most economically. The

proportion of concrete mix is obtained by experimentally evolved relationship between the factors in the

choice of mix design.

It provides reasonably accurate guide to arrive at an optimum proportion of ingredients. The final mix

proportion is obtained on the basis of trial mix. The mix design has been carried out as per stipulation of

Indian standard IS: 10262 guide line keeping in the view. The recommended mix standard deviation and

targeted mean strength. The recommended mix proportion should be tested at site for their workability and

strength.
