This paper analyzes the influence of SRA on the shrinkage-cracking property of HPC by designing five check-up experiments including desiccation-shrinkage, autogeous shrinkage, flat-restraint, anti-chloride ion penetration and ultimate tensile strain.

• 摘要设计了干燥收缩、自收缩、平板约束、抗氯离子渗透性以及极限拉应变等5种试验方法来检验减缩剂对高性能混凝土收缩开裂性能的影响。
