低相对湿度气相中水泥熟料单矿物的水化

Hydration of Cement Clinker Minerals in Reduced Relative Humidity Gas Phases

研究了水泥熟料单矿物C3S ,β C2 S和C3A在 40°C封闭气相中的水化情况 ,其中 ,气相相对湿度变化范围为 85 .0 %～ 99.0 % .结果表明 :C3S在气相中水化能力比较弱 ,在高相对湿度 (RH >97.5 % )气相中能逐步水化 ,但在低相对湿度 (RH =95 % )气相中 ,水化速率非常慢 ;β C2 S在气相中水化能力很弱 ;C3A在气相中水化能力比较强 .

The hydration of pure cement clinker minerals C3S, β-C2S and C3A were studied at 40°C in sealed gas phases. The relative humidity of gas phase varies from 85.0% to 99.0%. The results show that C3S can hydrate in gas phase with relative humidity higher than 97.5%, but its hydration rate is very low in gas phase with 95% relative humidity. β-C2S hydrates very little in gas phase. C3A hydrates well in gas phase.
