Portland Cement Clinker - an overview ScienceDirect Topics

The process that cement raw materials is sintered in a kiln is the key to the quality of cement clinker. In the sintering process of cement raw material, the useful components decomposed by various raw materials at 1000 °C are mainly: calcium oxide (CaO), silicon dioxide (SiO 2), aluminum oxide (Al 2 O 3), and ferric oxide (Fe 2 O 3).

Cement clinker - Wikipedia

The Portland clinker essentially consists of four mineral phases: two calcium silicates, alite (C3S) and belite (C2S), along with tricalcium aluminate (C3A) and calcium aluminoferrite (C4AFe). These main mineral phases are produced by heating at high temperature clays and limestone. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kilnat high temperature. The products of the chemical reaction aggregate together at their sintering temperature, a

RAW MATERIALS IN CEMENT PRODUCTION

Feb 07, 2019  The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.

A flux for cement comprises mainly wollastonite. By adding the flux 1-10% in preparing a cement raw material, the firing temperature may be reduced, the firing time may be shortened, coal consumption may be decreased and the productivity of cements may be improved. Also environmental pollution can be reduced and the compression strength and the bending strength of the cement can be improved.
