Abstract
gamma-dicalcium silicate(gamma-C2S) is known as a polymorphism of belite. Due to its high CO2 fixed capacity and the low CO2 emission production process,gamma-C2S has attracted more and more attention of researchers. For the further development of application of gamma-C2S in building construction industry. In this study, we aim to investigate the method for synthesizing high purity of gamma-C2S. The influence of different raw materials and calcination temperatures on the purity of gamma-C2S was also evaluated. Several Ca bearing materials were selected as the calcium source, the materials which' s main component is SiO2 were used as the silicon source. Raw materials were mixed and were calcined under different temperatures. The results reveal that the highest purity could be obtained using Ca( OH)(2) and SiO2 powder as raw materials. And for the practical application, a relatively economic synthesis method using natural mineral materials- limestone and silica sand as raw materials was developed, by this method, the purity of the synthetic gamma-C2S was 77.6%.
