水玻璃化学硬化机理的探索

Approach to Mechanism of Chemical Hardening of Water Glass

水玻璃用有机酯和ＣＯ２硬化时，模数升高到接近４．０，远没有达到析出游离硅酸的程度，因此水玻璃化学硬化依赖于硅凝胶生成的传统观点是不确切的。

When water glass is hardened by organic esters or CO 2,its modulus rises to about 4 0,far from precipitating free silicic acid,hence the traditional conception that the chemical hardening of water glass is dependent upon the formation of silicic dydrogel,is incorrect.
