Cement Works No 2 by Eric Revilious 1934. The essential components of cement Chemically cement is a mixture of calcium silicates and small amounts of calcium aluminates that react with water and cause the cement to set. Calcium derives from limestone and clay mudstone or shale as the source of the silica and alumina.
