Slump value has direct relation with water content in mix proportion
, and variations in water content (apart from minute changes in contents of other materials) influences the slump values proportionately.
Once the required mix proportion
has been fixed, the materials are weighed out as per requirement and mixed into a plastic mass by adding the required quantum of water.

Su 2001, Subramanian 2002 and EFNARC 2002 & 2005 were taken as references and the final SCC mix proportion

Prior to the construction of Tower 1, concrete mix proportion
contained 1200 to 1300 pounds of cementations material to produce 12,000 psi concrete.
We calculate both the optimal product mix proportion
Thus, we regressed fuel mix proportion
measures on the percent of a firm's sales subject to disclosure requirements and other covariates.
Based on this method the mix proportion
obtained was 1: 1.
