High Alumina Cement - Manufacture, Characteristics and Uses

24/08/2018  The process of manufacture of High Alumina Cement is different compared to that of ordinary portland cement. Bauxite and lime are used as the raw material. The raw materials are mixed in the required proportion and grinded into small fragments of 100 mm. These lumps are fed in kiln and heated up-to their fusion point which is 1600°C.

The Hydration of Calcium Aluminate Cements

12/09/2002  The dissolution process is typically said to be steady, but there is often more lime than alumina present in the solution. CaAl 2 O 4(5) + 4H 2 O -> Ca 2 + (aq) + 2Al(OH) - (aq) Barret and Bertandie claimed that this was due to the fact that small quantities of alumina gel precipitate out of the solution at the time of hydration, conforming to the following equation:
