- Abstract
- Gamma-C2S （γ-C2S）is a substance that is difficult to react with water under normal temperature but can absorb a large amount of CO2 in the air. The addition of γ-C2S to cementitious materials through the curing of CO2 can improve the pore structure and improve the durability of the material. In this study, three kind of Ca-bearing materials ：CaO, Ca(OH)2, CaCO3, were calcined 2.5h at 1450℃ to synthesize γ-C2S after mixing with SiO2 respectively. Among them, Ca(OH）2 mixed with SiO2 after calcining shows highest content. Synthesized γ-C2S was added to the cement mortar, after water curing for 1 month, accelerated carbonation test was experimented. After 28d accelerated carbonation test, pore structure will be detectived by MIP. Based on the MIP result, following the calculation method of Fractal theory, the pore structure will be quantitative described.
