Phosphogypsum as a construction material - ScienceDirect

10/11/2017  Phosphogypsum (PG) is a by-product generated from the phosphorus fertilizer industry (phosphoric acid production). PG is similar to natural gypsum, but there are some differences, of which it contains some impurities such as water-soluble phosphate (P 2 O 5), water-soluble fluoride (F −) and P 2 O 5 substituted in the gypsum crystal lattice. PG and gypsum are both calcium sulfate dihydrate.
