Cement Consistency Test - Standard Consistency of Cement ...

2021-8-14  By Standardising the consistency of cement, we know that how much of water is required to produce an effective cement which will eventually produce good quality of concrete. Standard Consistency of an ordinary Portland cement varies between 25-35%. That means we need 25% of water in volume to make a standard consistency of cement.
