水泥砂浆桩无侧限抗压强度试验研究
Experimental study of unconfined compressive strength of cement mortar pile
摘要
Abstract
Through the unconfined compressive strength test of cement mortar piles, the effects of sand content and curing time on unconfined compressive strength and initial tangent modulus of cement mortar pile were studied. The experimental results show that there is an optimal value of sand content, and the unconfined compressive strength has a linear relationship with the initial tangent modulus. Cement mortar piles subjected to unconfined compressive strength tests exhibit the brittle failure mode. With the increase of curing time and sand content, brittleness is increasingly significant.关键词
