Paper Title:
Study of Effect of Chemical Activators and Mineral Admixtures on the Strength of HFGD Gypsum - Fly Ash Cementing Material
  Abstract

A kind of FGD gypsum from Ningbo Beilun Power Plant of China and fly ash were used as the raw materials with which a complex cementing material was made. Effect of the related factors such as water proportion, mineral admixtures and chemical activators on characteristics of Hemi-hydrate FGD gypsum-fly ash complex cementing material is studied through a number of single factor experiments. The experimental results show that an appropriate amount of admixtures can effectively improve the strength of the Hemi-hydrate FGD gypsum–fly ash complex cementing material presented here. It is concluded that the strength of HFGD-FACM is best as the ratio of HFGD gypsum and fly ash is 1:1 and proper water aggregate proportion is 0.45~0.50.
