摘要：
An investigation is made into the effect of flue gas desulphurization (FGD) gypsum used in slag concrete on the gas permeability and chloride ion penetration property of the concrete. The results show that the strength of slag concrete can be enhanced if adding FGD gypsum. The coefficient of gas permeability of concrete declines and the chloride ion penetration resistance improves as well. FGD gypsum used as a useful composition of admixture in slag concrete can improve the penetration resistance of the slag concrete and enhance the durability. Therefore, two sorts of by-product can be recycled.
