METHOD OF MAKING CEMENTITIOUS COMPOSITIONS FROM WASTE PRODUCTS ABSTRACT Methods for producing cementitious compositions from waste products, such as non-ferrous slags, or fossil fuel combustion residue, or ferrous slags, whereby the CaO and alumina contents of the waste products are adjusted as necessary to enable them to combine with a sulphate additive at elevated pH and so couple the faster reactions of the mineral Ettringite with the slower ones of the calcium silicates.
