Belite cement and preparation method thereof
The invention discloses belite cement and a preparation method thereof. Belite cement clinker comprises mineral components in percentage by weight as follows: 40%-70% of dicalcium silicate, 10%-40% of tricalcium silicate, 6%-15% of tetra calcium aluminoferrite, 1%-10% of anhydrous calcium sulphoaluminate, 0%-8% of tricalcium aluminate and 0%-2% of calcium sulfate. A small number of anhydrous calcium sulphoaluminate minerals are introduced into the belite cement clinker, and on the basis that advantages of low calcium, low energy consumption, low requirements for raw material taste and the like of belite cement are not changed, the early strength of the belite cement is substantially improved and approaches that of ordinary cement; and the belite cement has a remarkable effect of resource and energy saving with utilization of low-grade limestone and industrial residue resources.
