糯扎渡水电站溢洪道抗冲耐磨混凝土拌和工艺及质量控制

Mixing Process and Quality Control of Abrasion-resistant Concrete for the construction of Spillway in Nuozhadu Hydropower Station

通过对抗冲耐磨混凝土原材料、拌和工艺等方面的质量控制管理,糯扎渡水电站溢洪道工程抗冲耐磨混凝土拌和物工作性能、混凝土强度、耐久性、抗冲耐磨强度均满足设计规范要求,为保证糯扎渡工程高流速溢洪道工程质量奠定了基础。

By controlling concrete quality fi＇om the aspects of raw materials and construction process, the performance, strength, durability and abrasion resistance of abrasion-resistant concrete mixture for constructing the spillway of Nuozhadu Hydropower Station meet the requirements of design specifications. The mixing process and quality control of concrete mixture lays the foundation for guaranteeing the construction quality of spillway with high flow velocity.
