摘要
为了研究水泥土的加固机理,寻求增加其早期强度的有效方法.本文以微晶作为添加剂,通过室内土工试验,证实了微晶添加剂可以增强水泥含量低的水泥土的早期强度,并且能够提高水泥土的抗折强度.不同龄期的微观观测发现:加入微晶可以提高水泥水化速度,改变水泥水化物在水泥土中的分布,从而有效充填水泥土中的微孔洞等缺陷,达到节材增强的效果.
Based on the data and the results of cement-stabilized soil (CSS)experimentation, it is verified that the early unconfined compressive strength of cement-stabilized soil can be improved, when the cement blend ratio is small. And the flexing strength falling can be delayed when the CSS is blended with proper ratio of micro-crystal. It is useful for other properties of cement-stabilized soil.
