Studies on Burning Process of Clinker Used for Corrosion-Resisting Cementitious Material in Fill Mining

Abstract:

Cemented filling body exposed to acid mine water or high salinity mine water will be subjected to various kinds of physical and chemical attack. In this paper, the burning process of a modified special cement clinker used for corrosion-resisting cementitious material in fill mining is studied by means of TG-DTA, XRD, and chemical method. The main minerals of this kind of clinker are C₃S, C₂S, C₄A₃ , and C₄AF. The optimal firing temperature range of the clinker is from 1300°C to 1380°C, and a suitable amount of F- and SO3 in raw meals is helpful to the coexistence of C₃S and C₄A₃ in the clinker.
