Cement-based cementing material for mass concrete as well as preparation method and application of cement-based cementing material
The invention belongs to the technical field of concrete materials and relates to a cement-based cementing material for mass concrete as well as a preparation method and application of the cement-based cementing material. The building material comprises the following raw materials in parts by weight: 2-5 parts of cement clinker, 70-90 parts of industrial waste residue, 13-15 parts of gypsum and 5-10 parts of nano inorganic filler. The cement clinker comprises silicate and/or sulphoaluminate; the industrial waste residues comprise at least one of steel slag powder, iron tailing slag powder and fly ash. The nano inorganic filler comprises at least one of kaolin, talcum powder, montmorillonite and silicon dioxide. The cement-based cementing material prepared by the invention has the characteristics of low water thermalization, high early strength, strong chemical erosion resistance and the like; meanwhile, the consumption of cement clinker is low, and the cost is greatly reduced.
本发明属于混凝土材料技术领域，涉及用于大体积混凝土的水泥基胶凝材料、制备方法和应用。原料组成按照重量份数计，包括：水泥熟料2‑5份、工业废渣70‑90份、石膏13‑15份和纳米无机填料5‑10份。所述水泥熟料包括硅酸盐和/或硫铝酸盐；所述工业废渣包括钢渣粉、铁尾矿渣粉和粉煤灰中的至少一种。所述纳米无机填料包括高岭土、滑石粉、蒙脱土和二氧化硅中的至少一种。本发明制备的水泥基胶凝材料具有低水热化、早期强度高、抗化学侵蚀能力强等特点；同时水泥熟料用量低，大大降低了成本。
