According to Lavoisier and Le Chatelier, 9 the reaction is a process of dissolving hemihydrate to create a super saturated solution of gypsum, from which gypsum is formed. This is possible due to the lower solubility of gypsum compared to hemihydrate. This theory is proven by Figure 4a - 4i and it shows why gypsum can act as an accelerator.

Normally oil is used as a fuel in white cement process, alternate fuels, like petroleum coke, rubber, agro waste, can also be used in white cement process due to high cost of oil.

prominent gypsum deposits began to occur. Gypsum is an evaporative mineral. During times of low sea levels and higher rates of evaporation, calcium (Ca 2 +) and sulfate (SO 4 2-) ions inevitably became concentrated enough for gypsum rock (CaSO 4 ·2H 2 O) to develop. The gypsum rock was then deposited on the sea floor which is now evident
