为了解偏高岭土对水泥土强度的影响,通过室内无侧限抗压强度试验,对不同偏高岭土掺量、不同龄期条件下的水泥土强度进行了测试。结果表明:当水泥掺量一定时,随着偏高岭土掺量的增加,水泥土抗压强度均有不同程度的增长;当偏高岭土掺量为3%时,水泥土抗压强度增幅达到普通水泥土抗压强度的27%左右。同时,对偏高岭土在水泥土中的作用机理进行了分析。
In order to understand the influence of metakaolin on the strength of cement soil, the strength of cement soil under different metakaolin dosage and different age conditions was tested by indoor unconfined compressive strength test. The results show that the compressive strength of cement-soil increases with the increase of metakaolin content. When the content of metakaolin is 3%, the compressive strength of cement-soil increases to that of ordinary cement Soil compressive strength of about 27%. At the same time, the mechanism of metakaolin in cement soil is analyzed.
