摘　　要：煤矸石泡沫混泥土利废减排,优越性显著,但是存在凝结时间长,成型不稳定的缺陷。文中主要研究加入早强剂,对泡沫混凝土各项性能的影响,结果发现不仅可以以激发煤矸石的活性,减小凝结硬化时间,而且还可以提高强度,改善孔结构,从而得到性能更优越的制品。Coal gangue foam concrete has advantages in reducing waste and reducing emissions,but it has the defect of long setting time and unstable forming.In this paper,the effect of adding early strength agent on the properties of foam concrete was studied.The results showed that it can not only simulate the activity of coal gangue,and reduce the setting time,but also improve the strength and pore structure,so as to obtain products with better performance.

关 键 词：泡沫混凝土 早强剂 凝结时间 抗压强度
