Potential use of phosphogypsum in alkali-activated fly ash under the effects of elevated temperatures and thermal shock cycles

Recycling of waste material is one of the effective solutions of its disposal problem. Fly ash (FA) and phosphogypsum (PG) take large disposal area and create serious environmental pollution like leaching and dusting. It is important to utilize these wastes as building materials to save the environmental from degradation. In this article, the possibility of recycling calcined PG (CPG) as a partial replacement of FA in alkali-activated FA (AAFA)...
