Abstract

In this paper, expansive soil is mixed with CKD in different proportions, and fast shear tests were conducted on the specimens with an certain initial water content and dry density; Furthermore, fast shear tests were also conducted for specimens with 10% CKD content ratio, when specimens were maintained for different curing ages separately, to investigate the effect of both CKD content ratio and curing age on strength property. Results showed that with the increase of CKD content ratios, shear strength was first increased, then decreased, the critical CKD content ratio was about 10%. And the cohesive force changes obviously, while the internal friction does not have a remarkable change. With the growth of the curing age, the shear strength increased exponentially, tending towards stability after about 28 days.
