Consistency refers to the relative mobility of a freshly mixed cement paste or mortar or its ability to flow.
Normal or Standard consistency of cement is determined using the Vicat’s Apparatus. It is defined as that percentage of water added to form the paste which allows a penetration of 10 ? 1 mm of the Vicat plunger.

It is the consistency at which the vicat plunger G of 10mm diameter and 50mm length will penetrate 33-35 mm within 3 to 5 minutes of mixing .
The test procedure is to carry at least three trial experiment by mixing the cement with distilled water varying from about 24 to 27 % of weight of cement .
