So the secret of the White cement is raw material. Apart from that only whitest chalk is used together with light colored sand in production of white cement. White cement production

Slurry and Clinker in Cement Making

Limestone (CaCO3) in 3 parts, and Clay in 1part are the raw material to make cement. These are mixed, grinded and water is added to make “slurry”. This slurry is heated to 1400-1500°C in rotary kiln. At 1000°C, the CaCO3 breaks into Quick Lime (CaO) and CO2. CaO reacts with Silica (SiO2), Alumina (Al2O3) and
