In order to explore the influence of types waste gypsum on properties alkali slag cement, fluorogypsum (FG) and flue-gas desulfurization (FGD) were comparatively investigated. Moreover, action mechanisms FG FGD cement analyzed. The results show that both prolonged setting time paste. However, prolongation effect was more pronounced than gypsum. When compressive strength maximum, contents 5 6 wt...

One of the most important characteristics of calcium phosphate cements is their resorbability when implanted in the body. However, the in vivo resorption rate is slow due to the lack of intrinsic open porosity. In this study, macroporous structures were obtained by mixing alpha-tricalcium phosphate (α-TCP) cement with a foamed liquid phase containing different concentrations of sodium hydrogen ...
