水泥外加剂对红黏土强度的影响
Effects of cement additive on the strength of red clay
摘要
Abstract
The quick shear experiments were carried out by drying red clay in some sites of Yanshan in Guilin re-spectively in different cement mixing ratio and under different moisture contents.In order to find out the optimal cement-mixing ratio of red clay,the relationships of the shear strength of red clay and cement dosage under the same moisture condition are researched.Under the condition of the same cement content,the relationship between the shear strength of red clay and the moisture content,test indicates that the shear strength of cement-treated soil increases with the increase of the ratio of cement mixing under the same moisture content.However,under the condition of the same ratio of cement mixing,the shear strength of cement-treated soil decreases with the increase of moisture content.In order to find out the suitable dosage of cement content and moisture content,the linear fit-ting chart and test data with origin software are analyzed.The results show that the shear strength of soil increases most obviously under the condition of the cement mixing ratio within 9% -13% and the moisture content 40%.关键词
