Valorization of industrial by-product: Phosphogypsum recycling as green binding material

Phosphogypsum (PG) from fertilizer industry represents an environmental problem, and it is usually discharged near the fertilizer plants. This waste is commonly stored in open piles, causing environmental impacts. When PG is calcined, it acquires binding properties. This paper had the objective to evaluate the use of recycled phosphogypsum (RPG), produced by PG calcination at low temperatures, for application in civil construction. The study...
