摘要
针对近年来混凝土结构早期开裂现象,从水泥比表面积、矿物组成、碱含量、外加剂等方面阐述了其对混凝土抗裂性的影响,在此基础上推荐使用环形试验评价水泥抗裂性,并针对如何提高混凝土抗裂性进行了探讨,提出了指导性建议。
In view of early concrete structure cracks phenomenon in recent years,it expounds its impacts on concrete crack resistance from aspects of specific concrete surface area,mineral composition,alkaloids content,and admixture,etc.,and recommends the usage of cycling experiment for evaluate the anti-crack cement.In the end,it discussion on how to improve concrete anti-crack,and puts forward guiding suggestions.
