- Name of Product: Portland Cement Clinker
- Quality: British Standard BS-12-1996
- Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature. The products of the chemical reaction aggregate together at their sintering temperature, about 1450°C. The major raw material for the clinker-making is usually limestone mixed with a second material containing clay as source of alumino-silicate.
- Usages: Portland cement clinker is grounded to a fine powder and used as the binder in many cement products. A little gypsum is sometimes added. It may also be combined with other active ingredients or chemical admixtures to produce different types of cement.
