用预水化法提高水泥早期强度的探讨

A disussion on improving the early strength of cement with pre-hydrated method

用普通水泥以一定方式预水化制成晶核，掺入该水泥中，研究其对水泥早期强度的影响。结果表明：该方法可使水泥胶砂３ｄ、７ｄ抗压强度分别提高１８．３％和１１．２％。

Crystal nuclei made from Pre-hydrated OPC were blended into cement and the effect of the crystal nuclei on the early strength of cement was studied. The results indicate that the 3d and 7d compressive strengths of cement are improved by 18. 3% and 1 1. 2% respectively by this method.
