| Abstract: | This paper studies the semi-water plaster stone using calcium sulphatewaste residue from the citric acid plant. We analyze its physics and chemistry,and the chemical composition of waste residue,and inquire into both dry and wet technological processes of the semi-water plaster stone. We have produce β-semi-water plaster stone and a -semi-weter plaster stone in accord with the Chinese National Standard of Building Material. |
