C_3S和β-C_2S单矿物在水蒸气中的水化

Hydration of C_3S and β-C_2S pure minerals in water vapor

研究了水泥熟料单矿物C3S、β C2 S分别在 2 0℃和 40℃水蒸气中的水化情况 ,气相相对湿度分别为 99%、97.5 %和 95 %。结果表明 :C3S在气相中水化能力比较弱 ,在高相对湿度 ( >97.5 % )气相中能逐步水化 ;提高气相温度后 ,C3S水化速度明显加快 ;但在低相对湿度 ( =95 % )气相中 ,C3S水化速度非常慢。β C2

The hydration of pure minerals C 3S and β C 2S were studied at 20 ℃ and 40 ℃ in water vapor . The relative humidity of gases are 99%, 97.5% and 95% respectively. The results showed that C 3S hydrated slowly in gas with relative humidity higher than 97.5%, the hydration was speeded up in higher temperature gas. But its hydration rate is too slow in gas of 95% relative humidity. β C 2S hydrates very little in gas.
