The use of phosphogypsum in the making of supersulphated cement(SSC) and mechanical properties of the SSC pastes were investigated. Setting times of SSC pastes were shortened with increasing phosphoanhydrite and Portland cement clinker content. The SSC pastes prepared using tap water were cured in b
Phosphogypsum, the by-product of phosphoric acid manufacture, is considered as a gypsum for the control of the setting time of Portland cement and trass cement. However, it is well known that impurities, usually included in phosphogypsum, injuriously affect the hydration of cement. The object of thi
The results of a comparison between the effects of sodium hydroxide and calcium hydroxide on poly(ethylene terephthalate) fabrics are presented. Calcium hydroxide can produce weight-loss effects similar to an aqueous solution of sodium hydroxide. The effects of some treatment variables on weight los
