High alumina cement - Designing Buildings Wiki

High Alumina Cement (HAC), sometimes known as calcium aluminate cement (CAC) or aluminous cement, is composed of calcium aluminates, unlike Portland cement which is composed of calcium silicates. It is manufactured from limestone or chalk and bauxite. HAC was first developed by Lafarge, the cement producer, and became available in the UK in 1925.
