Determine of normal consistency of Cement

The amount of water content that brings the cement paste to a standard condition of wetness is called “normal consistency”. It has a marked effect upon the time of set as well as upon other properties. The paste at normal consistency is fairly stiff and is used only for the determination of time of set and soundness.

This test method conforms to the ASTM standard requirements of specification C187. The usual range of values lies between 22 to 30 percent by weight of dry cement.
