    摘要: A method of making a cementitious composition comprises (a) selecting at least one pozzolanic particulate material; (b) selecting and grinding at least one feldspar material to a fineness of at least 3000 Blaine; (c) mixing calcium oxide or calcium hydroxide with gypsum; (d) mixing the ground feldspar with the lime-gypsum mixture to produce an activator; (e) conditioning the pozzolanic particulate material with an aqueous solution; (f) adding the activator to the conditioned material to produce a slurry; and (g) curing the slurry in a sealed container. The pozzolanic particulate material can be slag, fly ash, or siliceous rock. A cementitious composition of the invention comprises a pozzolanic particulate material, a ground feldspar material, a lime compound and gypsum, and uses readily available materials, as an economic replacement for Portland cement, fly ash or other materials in filling, backfilling and paving, particularly for backfilling or stabilizing mine sites.

    摘要: A method for treating a raw steel plant slag to transform it into a hydraulic binder at least equivalent to a Portland cement clinker, comprises the following steps: oxidizing treatment with input of oxygen, air or a mixture thereof at a pressure ranging between 1 to 15 bars, at a temperature ranging between 1650 and 1400° C., of raw steel slag containing, relative to the raw slag total weight, at least 45 wt. % of CaO and less than 30 wt. % of Fe2O3; and adding to the slag a lime source optionally with silica and/or alumina, so that the slag, after tranformation and at room temperature, has a propotion of Fe2O3 of less than 13 wt. % and a mineralogical composition comprising at least 40 wt. % in C3S mineralogical phase and more than 10 wt. %, of calcium ferrite, relative to the final slag total weight.
