摘要
红粘土是碳酸盐岩系出露区的岩石,在我国分布广泛,不同地区的红粘土表现的工程性质具有差异性。就湘中南地区的粘性红壤土通过不同水泥掺入比及不同龄期下的无侧限抗压强度试验,分析了水泥红粘土的强度增长机理,对试验结果进行了回归分析,给出了不同掺量、不同龄期水泥土之间的强度推算公式。
The red clay is a rock of carbonate. It distribution extensive in our country. The red clay representative otherness on engineering properties in differently region.. Through the unconfined compression tests which use the viscosity lateritic loamy that distribution at the suffer and south of the hunan province on the cement red clay with different cement ratio and different curing time. This paper analyses the gain in strength mechanism of the cement red clay. Through the regression analysis on the test result . Give out the prediction equation of strength on the cement red clay with different cement ratio and different curing time.
