摘　　要：采用水泥作为固化剂,氨基三甲叉磷酸(ATMP)作为缓凝剂,研究ATMP对延时制样水泥固化土性能的影响。结果表明,ATMP的掺入能有效对水泥固化土因延时制样导致的强度衰减产生缓解,水泥固化土的强度随着ATMP掺量的增加而减小,ATMP的最优掺量为0.02%。Using cement as a curing agent and amino trimethylene phosphate(ATMP)as a retarder,the effect of ATMP on the properties of delayed sample preparation cement stabilized soil was studied.The results indicate that the addition of ATMP can effectively alleviate the strength attenuation of cement stabilized soil caused by delayed sample preparation.The strength of cement stabilized soil decreases with the increase of ATMP content,and the optimal ATMP content is 0.02%.
