required cement temperature out of the mill

  • Composition of cement

    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.
