    This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3 000 o F to 2 600 o F). It hydrates rapidly but does not contribute much to strength of the cement paste. By mixing these compounds appropriately manufacturers can produce different types of cement to suit several construction environments.
