| 摘 要： | 结合水电工程的实际,对锂盐高效减水剂抑制碱硅酸反应(ASR)在水工混凝土中的应用进行了试验研究,结果表明,采用锂盐高效减水剂配制水工混凝土,不仅能使混凝土的综合性能满足设计要求,同时能有效抑制活性骨料ASR的膨胀变形,从而减少水工混凝土因ASR膨胀而产生破坏的风险。

| Abstract: | The application of lithium-based superplasticizer in inhibiting alkali-silica reaction(ASR) of hydraulic concrete is experimented for constructing a hydropower project.The results show that the concretes adding with lithium-based superplasticizer not only improve the overall performance of concrete to meet design requirements,but also effectively suppress the ASR expansion deformation of reactive aggregate to reduce damage risk of hydraulic concrete. |
