摘要
本文设计了干燥收缩、自收缩、平板约束、抗氯离子渗透性以及极限拉应变等5种试验方法来考核减缩剂对高性能混凝土收缩开裂性能的影响。研究结果表明:减缩剂能够改善高性能混凝土的工作性、对混凝土的力学性能无负作用、能够有效的提高混凝土的抗裂性能。
This paper is to analyzed the influenced effect on shrinkage-cracking property of HPC by SRA, by means of designing five check-up experiments such as desiccation-shrinkage, autogenous shrinkage, flat-restraint,anti-chloride ion penetration and ultimate tensile strain etc. The results is to approve that SRA can improve the workability of HPC, and promote effectively anti-cracking performance, without coming negative effect into mechanics property.
