Influence of Treated Phospho-Gypsum on Physiochemical Characteristics of Slag Cement

In around half a century, ۱.۰ × ۱۰۸ tons of Phospho-gypsum have been generated and gathered in the vicinity of fertilizer manufacturers. Fifteen percent of the PG byproduct has been treated; the remaining almost eighty-five percent has been kept in storage and dumped in landfills. Generally, reducing waste disposal generally has advantages for the environment and economic growth. Therefore, the incorporation of PG into building materials is a clever way to reduce the expenses associated with producing cement and with disposing of Phospho-gypsum as radioactive and chemical waste. PG has been extensively researched for application in various industries, including soil stabilizing supplements, farming fertilizers, set controllers in cement manufacturing, and construction resources. The current study elaborated on the influence of the substitution Raw- Gypsum with treated Phospho- Gypsum on the physical and chemical characteristics of Slag Cement (CMIII/A). PG is treated at different temperatures by heating in an electrical furnace ranging from ۲۰۰ to ۱۰۰۰ °C. The study results were validated and positively impacted the environment and cost of cement manufacturing.
