Abstract
  The present study conducted to investigate the potential use of PG in cement industry. This was accomplished by preparing mortar mixes contain Portland cement clinker (PPC) with thermally treated PG at different temperatures (200, 400, 600, 800 and 1000 °C) instead of raw gypsum (RG) at different ...  Read More

Abstract
  For many years of production of phosphate fertilizer very large amounts of phosphogypsum (PG) occupied large area, causing chemical and radiological environmental. Using of PG in building materials represents a good method for lowering the cost of cement production and dispose of phosphogypsum as chemical ...  Read More
