摘要

In this paper, the flue gas desulfurization gypsum (FGD) generated from thermal power plant is used to produce high strength gypsum. Compared with the properties of high strength gypsum using natural gypsum, the basic properties of super high strength gypsum prepared by FGD gypsum are investigated based on the test results of strength, thermal expansion rate, crystal appearance and size. The results indicate there is little difference of the properties of high strength gypsum prepared by FGD gypsum and natural gypsum. And furthermore, the FGD gypsum can be used as the good raw material of high strength gypsum preparation instead of natural gypsum.
