摘要 A self-designed restrained ring test was applied to investigate cracking of mortar.The cracking total weigh W and cracking control rate K were applied to evaluate anti-cracking performance of mortar.Through the above method,the influence of polymer on the shrinkage and anti-cracking performance was studied.The microstructures of mortar specimens were investigated by means of SEM.The results indicated that the addition of polymer can efficiently reduce the shrinkage of mortar and improve the anti-cracking performance of mortar.
