Superfine powder special for commercial concrete and preparation method thereof
The invention discloses superfine powder special for commercial concrete and a preparation method of the superfine powder. The superfine powder is prepared from the following raw materials: superfine slag micropowder, superfine fly ash, silica fume, first-grade fly ash, high-calcium powder, gypsum, microbeads, a grinding aid, an exciting agent and a powder water reducing agent. The special concrete admixture for commercial concrete is prepared from industrial waste residues such as superfine slag powder, silica fume and microbeads as main raw materials through the technological processes of coarse grinding, superfine grinding, mixing and stirring and the like, the original characteristics of low hydration heat and good durability of the concrete admixture are reserved, and meanwhile, the strength of the concrete admixture within 3 days can reach the strength of PO42.5 cement; the prepared cement has the advantages that the strength of the cement in 28 days is far higher than that of PO42.5 cement, and the cement can be widely applied to commercial concrete of various strength grades, is low in water demand, good in peaceability, high in strength, good in activity and durability, strong in adaptability with cement and additives and excellent in performance when being used in the commercial concrete, and the dosage is obviously reduced, so that the concrete blending cost is reduced to a certain extent.
本发明公开一种商品混凝土专用的超微粉及其制备方法，包括以下原料：超细矿渣微粉、超细粉煤灰、硅灰、一级粉煤灰、高钙粉、石膏、微珠、助磨剂、激发剂和粉体减水剂；本发明以矿渣微粉、硅灰和微珠等工业废渣作为主要原料，并经粗磨加工、超细粉磨加工和混合搅拌等工艺流程制成商品混凝土专用混凝土掺合料，不但保留其原有水化热低，耐久性好的特性，同时其3天强度即可达到PO42.5水泥强度，28天强度远高于PO42.5水泥强度，可广泛用于各种强度等级的商品混凝土中，用于商品混凝土中不仅需水量低、和易性好、强度高，活性和耐久性也好，与水泥和外加剂适应性强，不仅性能优异，且用量显著降低，一定程度上降低了混凝土掺和成本。
