N2 - The lower environmental impact and economic cost of cements made from waste materials makes them an attractive alternative to Portland cement. This research was undertaken to study the performance of cement made by sulfate activation of a basic oxygen slag and run-of-station ash blended with red gypsum and plasterboard gypsum. Two-component and three-component mixes were tested as part of a systematic process of optimising for strength. All mixes had similar water to binder (w/b) ratio 0·3. The results showed plasterboard gypsum and red gypsum can be used with sulfate to form a sulfate-activated pozzolan basic oxygen slag run-of-station ash binder. Sample solutions were collected from a high-pressure through-flow test and analysed using inductive coupled plasma to measure the risk of leaching of heavy metals.
