低碱膨胀剂和缓凝高效减水剂双掺技术在防水抗渗混凝土工程的应用

The application of low alkali expanding admixture and set retarding superplastic izer admixture in waterproofing and anti-leakage structure

通过低碱膨胀剂和缓凝高效减水剂双掺技术在华林大厦和福耀浮法联合车间混凝土结构自防水中应用两个工程实例证明,采用双掺技术可以防止混凝土早期收缩产生的裂缝,从而提高混凝土抗渗性满足防水抗渗施工要求。

Based on the application of low alkali expanding admixture and set retarding superplasticizer admixture on self-waterproofing of concrete struct ure of Hualin Hall and Fuyao Float-Glass Workshop,this article demonstrates th at the application can prevent the emergence of crack due to early shrinkage,and thus enhance the anti-leakage performance of the concrete and satisfy the req uirement of waterproofing and anti-leakage.
