Study Formation Process of Cement Clinker Minerals by Using Calcium Carbide Slag as Raw Material

Abstract:

Calcium carbide Slag is one kind of industrial wastes from CaC₂ hydrolysis reaction that will cause land pollution. In the research, calcium carbide Slag used as a substitute for limestone to produce cement clinker, which with a high portion of CaO content and then an excellent calcium containing raw material. As a kind of industrial wastes, the properties of Calcium carbide slag differentiate from that of natural limestone. The formation process of clinker minerals was studied by means of XRD. The results indicated that clinker minerals formation is similar to that from use of limestone. The generated clinker has a rational mineral composition and well developed mineral phase structure. But, there are many differences in decomposition temperatures between the calcium containing raw materials. Therefore, the carbide slag can be used as a substitute of limestone raw material to produce cement clinker.
