In the nominal mix concrete, all the ingredients and their proportions are prescribed in the standard specifications.these proportions are specified in the ratio of cement to aggregates for certain strength achievement.. the mix proportions like 11.53, 124, 136 etc. are adopted in nominal mix of concrete without any scientific base, only on the basis on past empirical studies.
