Cementing material reinforcing agent with high fly ash mixing amount, preparation method of cementing material reinforcing agent, concrete and preparation method of concrete
The invention discloses a cementing material reinforcing agent with high fly ash doping amount, a preparation method of the cementing material reinforcing agent, concrete and a preparation method of the concrete, and belongs to the field of cement chemical industry. The cementing material reinforcing agent with the high fly ash doping amount comprises waste salt and carbide slag, the waste salt at least contains 60% of sodium sulfate, the carbide slag at least contains 80% of calcium hydroxide, and the cementing material reinforcing agent with the high fly ash doping amount is used for improving the 28-day strength of a cementing material for mine backfilling. The cementing material contains at least 80% of fly ash. The cementing material reinforcing agent with high fly ash doping amount provided by the invention is low in cost and has an excellent effect of improving the strength of a cementing material in concrete.
本发明公开了一种高粉煤灰掺量的胶凝材料增强剂及其制备方法、混凝土及其制备方法，属于水泥化工领域。所述高粉煤灰掺量的胶凝材料增强剂包括：废盐和电石渣，所述废盐中至少含有60％的硫酸钠，所述电石渣中至少含有80％的氢氧化钙，所述高粉煤灰掺量的胶凝材料增强剂用于提升矿井回填的胶凝材料的28天强度，所述胶凝材料中含有至少80％的粉煤灰。本发明提供的高粉煤灰掺量的胶凝材料增强剂成本低廉且对混凝土中胶凝材料的强度提升效果优异。
