合理使用外加剂能改善混凝土的工作性能和力学性能，但使用不当将导致混凝土不能在规定的时间内正常凝结硬化，甚至造成混凝土强度的降低，最终导致混凝土结构出现质量事故。通过一系列试验分析了减水缓凝剂超掺对混凝土性能的影响，总结了超掺不同倍数时对混凝土凝结时间和强度的影响。

Reasonable use of admixture can improve the concrete performance and mechanical performance, but the improper use will lead to concrete can't produce condensation and hardening within the the normal time, and even the strength of concrete is reduced, eventually leading to concrete structure appear quality accident. This paper analyzes con- crete performance influence for the water-reduction retarder super blending through a series of tests, and summarizes the influence of the concrete setting time and strength for the different ratio of super blending.
