复掺剂对硫铝酸盐型膨胀剂效能的影响

The combined admixture influences on sulphoaluminate typed expansion agent potency

研究了减水剂、缓凝剂、引气剂三种外加剂复掺对掺膨胀剂胶砂试件自由膨胀率和限制膨胀率的影响,得出了它们对膨胀剂膨胀效能的影响规律,从而帮助人们确立最佳应用配比,取得较好的技术经济效益。

The water redtlcing agent, delay combustion agent and air entrain agent combined admixture influences on mortar free expansion ra- tio and limit expansion ratio mixed with expansion agent were studied, their influences rule on expansion agent expansion potency was obtained therefore helped human build best utilization match ratio and obtained better technical economic efficiency.
