Learn MoreWhile the most common mix ratio is the 1:2:4 (cement-fine aggregate-large aggregate); other mix ratios such as the 1:1.5:3 and 1:1:2 have also been tested (Adewole et al., 2015). Concrete grade ...

Learn MoreBased on structural design requirements the grade of concrete construction is selected and there are two types of concrete mixes, design mix & nominal mix. The grades of concrete are converted into mix proportions consider for M20 concrete mix proportion will be 1: 1.5: 3 (cement, sand and coarse aggregates).

Learn MoreThe water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix ...
