Abstract
Calcium carbonate‐silica mixtures produced by carbonation of wollastonite and pseudowollastonite and by intergrinding precipitated CaCO3 with SiO2 flour were calcined. At calcination temperatures of 2SiO4 and CaO were formed. The quantities of these products were determined by X‐ray diffraction, and their dependence on calcination time, temperature, and the degree of homogeneity of the starting material was determined. Kinetic data were also obtained. Calcined materials mixed with water and compacted under pressure hardened slowly at room temperature and more rapidly under atmospheric steam or autoclave conditions. The relation between compressive strength, porosity, curing time, and temperature was determined.Keywords
