基于无侧限抗压强度试验的不同养护环境对水泥土强度影响研究OA

Based on the road engineering project of Liancheng Road(section from Shugang Road to Xueyuan Road)in Ningde City,Fujian Province,an unconfined compressive strength test system was used to study the effects of different curing condition,cement dosages and curing ages on the strength of cemented soil.The results show that when the cement content and curing age are the same,the unconfined compressive strength of cemented soil in the test box is lower than that in the standard curing box;With the same cement content,both the unconfined compres-sive strength of cemented soil in the two boxes are positively correlated with the curing age,that is,it increases with the increase of curing age,but its strength growth rate gradually decreases with the increase of curing age;Under the same curing age and different curing conditions,the unconfined compressive strength of cemented soil increases with the increase of cement content,and the difference in strength between the specimens in the test box and the standard curing box gradually accelerates with the increase of cement content.
