混凝土复合外加剂与单独使用一种外加剂相比,具有更多的功能。为此而研究包括氯盐和硫酸盐在内的复合外加剂,以增加水泥熟料矿物中石灰和二氧化硅的溶解度。当混凝七中掺入氯化钾和硫酸钠时,其强度增长最快。复合外加剂中硫酸钠效果最好,但是由于中铝和高铝水泥混凝土掺加这种外加剂时28天强度较低,所以不经济。另一种外加 Concrete composite admixtures have more functionality than using an admixture alone. For this purpose, composite admixtures including chloride salts and sulfates were studied to increase the solubility of lime and silica in cement clinker minerals. When potassium chloride and sodium sulfate are incorporated into the coagulation seven, their strength increases fastest. The effect of sodium sulfate in the composite admixture is best, but due to the low strength of the 28-day admixture of China Aluminum and high alumina cement concrete, it is not economical. Another kind of extra
