水泥土无侧限抗压强度试验

Unconfined compression strength test for cement-soil

为探讨水泥含量、龄期和含水率对水泥土无侧限抗压强度的影响,分别对水泥含量为2%,4%,6%,8%和10%,龄期分别为7 d,14 d和28 d,含水率为2%,4%,6%,8%和10%水泥土试样进行无侧限抗压强度试验。结果表明,随水泥含量和龄期增大,水泥土无侧限抗压强度增大;随含水率增大,水泥土无侧限抗压强度先增大后减小,含水率约为6%时,其强度达到最大值。

In order to discuss the influence of cement content, age and moisture content on unconfined compression strength of cement-soil, lots of the unconfined compression strength tests are made under the condition of the different cement-soil samples. The cement content is respectively 2%, 4%, 6%, 8% and 10%, the age is respectively 7d, 14 d and 28 d and the moisture content is respectively 2%, 4%, 6%, 8% and 10%. The results show that, the unconfined compression strength of cement-soil increases with the cement content and the age increasing, the unconfined compression strength of cement-soil increase first and then decrease with moisture content increasing, when the moisture content is about 6%, its strength reaches its maximum.
