Manufacturing properties of γ-dicalcium silicate with synthetic method

다국어 초록 (Multilingual Abstract)

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