2021-11-26  Water cement ratio (w/c ratio) is defined as the ratio of the weight of water to the weight of cement used in the concrete mix. Normally, about 38% of water is required for the complete hydration of concrete. As per IS 10262 (2019) for nominal mix ( i.e. M10, M15, M25); the w/c ratio varies from 0.4 to 0.6. 2.

2021-12-1  Water cement ratio above 0.6 makes concrete too flowy and strength is reduced drastically. Water cement ratio below 0.4 gives stiff concrete which has very low workability to handle the concreting operations. In such cases, admixtures enhancing flowability can be added to produce high strength concrete.
