Abstract

In order to study strength and evaluate its quality of cement-soil in on-site construction process, unconfined compressive tests and triaxial CU shear tests were carried out on cement-soil core samples. The analysis of effects of cement mixing content, water cement ratio and lifting speed on strength and deformation properties of cement-soil was made. The results show that with the improvement of cement mixing ratio, the strength of cement-soil core samples is enhanced obviously, deformation modulus increases significantly, but the failure strain decreases, brittleness increases. And in the same conditions of cement mixing ratio, the strength of cement soil is higher when water cement ratio is 1.0 than that when water cement ratio is 0.8. And as the lifting speed increases, the density and strength of cement soil core samples are significantly reduced. This paper introduces the concepts of standard value, variable coefficient and modulus ratio, which can evaluate the density of cement soil core samples, unconfined compressive strength and the triaxial CU shear strength. This paper gives rational advice and is certain guide significance for practical projects.
