利用工业废渣制备复合型高膨胀性胶凝材料及其制备工艺
摘要：
本发明涉及利用工业废渣制备复合型高膨胀性胶凝材料及制备工艺，该胶凝材料，由组分(i)包括三部分，即粉煤灰、矿渣等含硅铝酸盐成分的一种或多种组合；磷石膏、氟石膏等含有硫酸钙的一种或多种组合，电石渣、碱渣、生或熟石灰中的一种或多种组合；组分(ii)的包括生或熟石灰、电石渣等碱性组分的一种或多种组合；组分(iii)包括磷石膏、氟石膏等含有硫酸钙的一种或多种组合；其制法是：(1)将组分(i)的原料混合拌匀，经4小时～10天50-100℃蒸汽养护，于400-1000℃高温下煅烧处0.5-24h，磨细至比表面积200-500m2/kg，得组分(i)；(2)将组分(ii)、(iii)原料烘干、磨细至比表面积200-500m2/kg，得组分(ii)、(iii)；(3)将组分(i)、(ii)、(iii)均匀混合。
摘要（英）：

The invention relates to a preparation process of using industrial slag to prepare composite cementing materials with high expansibility. The cementing materials consist of four components. The first component includes three parts: one or a plurality of combinations of fly ashes, slag, etc., which contain aluminosilicate; one or a plurality of combinations of phosphogysum, fluorine gypsum, etc., which contain calcium sulfate; one or a plurality of combinations of carbide, alkaline residue, quick lime or slaked lime. The second component includes: one or a plurality of combinations of alkaline composition, such as the quick lime or slaked lime, the carbide slag, etc.. The third component includes one or a plurality of combinations of the phosphogypsum, fluorine gypsum, etc., which contain the calcium sulfate. The preparation method is: firstly, to evenly mix the raw materials of the first component which are grinded to be with the surface area of 200-500m<2>/kg through the steam curing of four hours to ten days at 50-100 DEG C and the calcining of 0.5-24h at the high temperature of 400-1000 DEG C to obtain the first component; secondly, to dry and grind the raw materials of the second and the third component to be with the surface area of 200-500m<2>/kg to obtain the second and the third component; thirdly, to evenly mix the first, the second and the third component.
