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

The cement kiln

The dry process is much more thermally efficient than the wet process. Firstly, and most obviously, this is because the meal is a dry powder and there is little or no water that has to be evaporated. Secondly, and less obviously, the process of transferring heat is much more efficient in a dry process kiln.
