摘　　要：根据目前C60高性能混凝土的水胶比低、粘度大、泵送阻力大等缺点,通过采用混凝土"双掺"技术,提高混凝土的初始坍落度及扩展度,控制坍落度和扩展度的经时损失,降低混凝土拌合物粘度。配制出的C60高性能混凝土具有大流动性、良好的工作性和可泵性能较好,工程实际应用效果良好。According to some disadvantages such as low water-cement ratio,large viscosity,large resistance to pumping of C60 highperformance concrete at present,it can improve slump and extended degree of the initial concrete,and can control loss by the time of slump and extended degree,and can reduce the viscosity of concrete mixture by double-mixed technology.The C60 high-performance concrete has high fluidity,good workability and pumping performance,and it has good effect in the practical application of engineering.
