Calcium silicate hydrate, a colloidal and mostly amorphous gel with a variable composition this is the major hydration product of Portland cement, constituting approximately 70 percent of the paste, and is the phase providing most of the strength and binding. A Minimum quantity of water required to initiate the chemical reaction between water and cement to form a paste is known as consistency of cement. 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.
