Modified composite concrete early strength agent
The invention discloses a modified composite concrete early strength agent, and relates to the technical field of early strength agents. The early strength agent comprises the following components inparts by weight: 20-30 parts of triethanolamine, 10-20 parts of silica fume, 5-15 parts of modified bentonite, 2-6 parts of modified polyacrylonitrile fiber, 0.5-1.5 parts of water-soluble silicate, 0.3-0.8 part of water-soluble calcium salt, 0.1-1 part of sodium hydroxide and 0.1-0.3 part of water reducing agent. The added modified bentonite has certain reaction activity, so that the cohesivenessof the concrete can be improved; by adding the modified polyacrylonitrile fiber, the toughness and the fracture property of the concrete can be improved; in addition, through the synergistic effect and reasonable configuration of different raw materials, the performance of the concrete can be effectively improved, the construction efficiency is improved, the production cost is saved, and the concrete has the advantages of low slump, high compressive strength and low bleeding rate.
本发明公开了一种改性复合混凝土早强剂，涉及早强剂技术领域，所述早强剂按重量份包括以下组分：三乙醇胺20～30份、微硅粉10～20份、改性膨润土5～15份、改性聚丙烯腈纤维2～6份、水溶性硅酸盐0.5～1.5份、水溶性钙盐0.3～0.8份、氢氧化钠0.1～1份和减水剂0.1～0.3份。本发明添加的改性膨润土具有一定的反应活性，能够提高混凝土的粘结性；通过添加的改性聚丙烯腈纤维能够提高混凝土的韧性及断裂性；且本发明通过不同原料的协同作用以及合理配置，能够有效改善混凝土的性能，提高施工效率，节约生产成本，本发明具有坍落度低、抗压强度高、泌水率低的优点。
