Manufacturer page.EPD: Portland composite cement, CEM II, 52.5 N (Lafarge Cement S.A.)
The main component of cements according to EN 197-1 is clinker. It is produced from raw materials such as limestone and clay, silica or other waste materials which are crushed, homogenized and fed into a rotary kiln. The raw materials are sintered at a temperature of 1450°C to form new compounds. Clinker consists mainly of oxides of calcium, silicon, aluminum and iron. In a second phase calcium sulfates and possibly additional cementitious or inert materials are added to the clinker. All constituents are ground leading to a fine and homogenous powder.
