Abstract

The effects on the setting and mechanical properties of partly-refined boro- and phosphogypsum mixed with Portland and trass cements were studied and compared with a Portland cement containing high grade natural gypsum. It was found that the partly refined boro- and phosphogypsum can be used in place of natural gypsum for Portland and trass cements. Reasons for the observed properties of the Portland and trass cements containing the aforementioned chemical gypsum are concluded.
