Regenerated micro-powder admixture, preparation method thereof and application thereof as cement substitute
The invention discloses a regenerated micro-powder admixture, a preparation method thereof and an application of the regenerated micro-powder admixture as a cement substitute. The regenerated micro-powder admixture is prepared from regenerated micro-powder, acidic silicon slag, limestone, zeolite and a grinding dispersant as raw materials through wet grinding at 7090 DEG C and drying. The regenerated micro-powder admixture can effectively improve the inertia of regenerated micro-powder, replace the dosage of a cement cementing material, improve the early strength of cement and improve the initial fluidity of mortar, and has remarkable economic and environmental benefits.
本发明公开了一种再生微粉掺合料及其制备方法和其做水泥替代物的应用，所述再生微粉掺合料以再生微粉、酸性硅渣、石灰石、沸石、研磨分散剂为原料在70‑90℃下经湿磨后烘干而成。所述再生微粉掺合料可以有效提高再生微粉惰性，替代水泥胶凝材料的用量，提高水泥早期强度，改善砂浆初始流动度，具有显著的经济和环保效益。
