Fundamentals of Concrete

the unit weight of a dry material (gdry) divided by the unit weight of water (gwater). Gs = gdry / gwater or gdry = Gs x gwater To determine the unit weight of a substance like cement, multiply the specific gravity of the cement by the unit weight of water. gcement = 3.15 x 62.4 lb/cu ft = 196.56 lb/cu ft Bulk specific gravity of concrete materials

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
