EXPERIMENTAL STUDIES OF THE HIGH BELITE SULPHOALUMINATE CEMENT

摘要

In this paper the clay as correcting material, adjusts the silica content of the raw material, thus adjusts the proportion of the tribalism sulphoaluminate and the dicalcium silicate in the clinker. The influence of proportion of C_4A_3S and C_2S on the properties of sulphoaluminate cement was studied. By aid of X ray diffraction analysis method and scanning electron microscope analysis method, we have carried on study and analysis of various set of samples; and determined that when we compound high Belite sulphoaluminate cement, the silica content of the clinker should be controlled smaller than 20%. The thesis provides the theoretical basis for using low-grade alumina and high silica industry waste to produce high Belite sulphoaluminate cement.
