TL;DR: In this article, aqueous citric acid solution was attempted to purify phosphogypsum and improve its quality to make it fit for manufacture of cement and gypsum plaster for the first time.

TL;DR: In this article, the effect of adding calcined clay in these types of binders was studied and the results showed that fly ash can be used in the range from 45% to 70% in formulating these binders along with other industrial wastes to help in mitigating environmental pollution.

TL;DR: In this article, the formation of anhydrite cement was examined by microscopy and X-ray diffraction and the effects of different chemicals on setting and hardening of an hydration characteristics were studied.

TL;DR: In this paper, the compressive strength of a cementitious binder based on calcined phosphogypsum, flyash, hydrated lime and portland cement was studied at room temperature and at 50 °C in over 90% RH.

TL;DR: In this paper, a mechanism of conversion of anhydrite into gypsum through transient double salts in presence of activators is suggested, and the correlation between gain in strength and hydration products is reported.
