There have been several attempts to manufacture building materials from phosphogypsum in different countries. For example, phosphogypsum was used some time ago by a New Jersey company for the manufacture of wallboard, partition blocks, and plaster for distribution in the northeastern United States (Fitzgerald and Sensintappar, 1978). Due to the absence of low-cost natural gypsum and the lack of long-term storage place, phospho-gypsum has been used extensively for wallboard and other building
