Crystal nucleus reinforcing agent, cementing material and preparation methods of crystal nucleus reinforcing agent and cementing material
The invention relates to the technical field of building material admixtures, in particular to a crystal nucleus reinforcing agent, a cementing material and a preparation method of the cementing material. The crystal nucleus enhancer is prepared by adopting a chemical coprecipitation method, and used raw materials comprise a sodium metaaluminate solution, a nano aluminum oxide suspension water glass solution, calcium hydroxide, a sodium hydroxide solution, an alcohol amine polar small molecule accelerant solution, a strong anchoring type polymer dispersant solution and water. When the crystal nucleus reinforcing agent is used for a cement-fly ash cementing material containing 1-50% of fly ash and the doping amount of the crystal nucleus reinforcing agent is 0.5-5% of the total weight of the cementing material, the initial setting time and the final setting time are respectively shortened by 11.9-41.5% and 13.7-41.5%, the 8h strength is improved by 45.3-172.1%, and the 28d strength is improved by 3.4-10.9%. The crystal nucleus reinforcing agent disclosed by the invention has extremely excellent dispersion stability and early strength performance, and has a large-scale application potential in the field of steam-curing-free preparation of cement-fly ash-based concrete prefabricated components.
本发明涉及建筑材料外加剂技术领域，尤其涉及一种晶核增强剂、胶凝材料及其制备方法。晶核增强剂采用化学共沉淀法制备，所用原料包括偏铝酸钠溶液、纳米氧化铝悬浮液水玻璃溶液、氢氧化钙、氢氧化钠溶液、醇胺极性小分子促进剂溶液、强锚固型高分子分散剂溶液和水。将晶核增强剂用于粉煤灰含量为1～50％的水泥‑粉煤灰胶凝材料，且掺量为胶凝材料总重量的0.5～5％时，初、终凝时间分别缩短11.9～41.5％和13.7～41.5％，8h强度提高45.3％～172.1％，28d强度提高3.4～10.9％。本发明晶核增强剂具有极其优异的分散稳定性和早强性能，在水泥‑粉煤灰基混凝土预制构件的免蒸养制备领域具备大规模应用的潜力。
