Study on the Mechanical Properties of Cement Soil under Different Mix Proportions
The influence of cement,mineral powder,fly ash content,and curing age on the unconfined compressive strength of cementitious soil was studied through orthogonal experimental method.The results show that the cement content has the most significant impact on the uncon-fined compressive strength of cementitious soil during the hardening process.;When the cement content is 18%,the mineral powder content is 12%,and the fly ash content is 12%,the cement soil strength is the highest.Under a smaller cement content,the strength of cementitious soil increases significantly.As the cement content continues to increase,the growth rate of cementitious soil strength slows down;With the increase of mineral powder content,the strength of cementitious soil shows a trend of first increasing and then decreasing;With the increase of fly ash content,the strength of cementitious soil shows a trend of first decreasing and then increasing.
