Fly ash modifier as well as preparation method and application thereof
The invention relates to a fly ash modifier as well as a preparation method and application thereof, and belongs to the technical field of building materials. The fly ash modifier is prepared from the following raw materials in parts by weight: 20-30 parts of powder I, 50-70 parts of powder II, 5-10 parts of a solid polycarboxylate superplasticizer, 2-5 parts of a surfactant, 3-8 parts of polyol and 0.5-1 part of organic alcohol amine, wherein the powder I is selected from at least one of sodium sulfate, calcium sulfate, aluminum sulfate and alum; and the powder II is selected from at least one of calcium oxide, calcium formate and slaked lime. The fly ash modifier is applied to the fly ash grinding production process, the grinding efficiency can be effectively improved, and the activity of fly ash is improved.
本发明涉及一种粉煤灰改性剂及其制备方法和应用，属于建筑材料技术领域。该粉煤灰改性剂由以下重量份的原料制备而成：粉剂I 20～30份，粉剂II 50～70份，固体聚羧酸减水剂5～10份，表面活性剂2～5份，多元醇3～8份，有机醇胺0.5～1份，粉剂I选自：硫酸钠、硫酸钙、硫酸铝、明矾中的至少一种；粉剂II选自：氧化钙、甲酸钙、熟石灰中的至少一种。本发明的粉煤灰改性剂应用于粉煤灰研磨生产过程中，能有效提高研磨效率，提升粉煤灰的活性。
