The effects of anti-cracking agent on mechanical properties and drying shrinkage properties of concrete were studied.The effects of anti-cracking agent content,curing conditions and pouring temperature on cracking risk of raft foundation concrete were compared by finite element software,and an economical and reasonable temperature con-trol scheme was proposed.The results show that the compressive and splitting tensile strength of concrete with 5％an-ti-cracking agent content was the highest,and the drying shrinkage of concrete at 56 d was 24.5％lower than that of ordinary concrete.The raft foundation achieved good crack control effect by using water-saving moisturizing film and cotton-covered maintenance measures.
