Study on the Effect of Waste Gypsum on Hardening Paste Structure and Performances of Lime-fly ash

摘要：

Based on the experiments，the effect of waste gypsum on the formation of paste structure， the early strength and the stability of lime-fly ash is discussed in the article．As is shown by the results， the early strength of paste was improved by adding waste gypsum into lime-fly ash．The stability of lime-fly ash paste modified by waste gypsum could meet technical requirements when waste gypsum admixture was less than 40％．With the increase of hydration age，the number of ettringite(Aft)and C-S-H gel in paste would increase．

关键词： waste gypsum lime-fly ash paste structure strength
