  • Portland cement and the environment Concrete

    Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about °C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.
