Anti-cracking reinforcing agent with micro-expansion characteristic as well as preparation method and application of anti-cracking reinforcing agent
The invention discloses an anti-cracking reinforcing agent with a micro-expansion characteristic. The anti-cracking reinforcing agent comprises the following components in parts by mass: 65-90 parts of lithium slag, 15-35 parts of fly ash, 10-20 parts of steel slag micro-powder, 10-30 parts of mineral powder, 0.5-2 parts of a polycarboxylate superplasticizer, 1-3 parts of sodium carbonate and 0.8-2.4 parts of sodium hydroxide. According to the invention, industrial by-products, a water reducing agent and an alkali activator are utilized to prepare the anti-cracking reinforcing agent dry blend with potential micro-expansion characteristics, and the anti-cracking reinforcing agent dry blend aims to improve the mechanical property and the shrinkage property of a cement-based material. Meanwhile, through resource utilization of the industrial solid waste, not only is the damage of the industrial solid waste to the environment reduced, but also the cyclic utilization of resources is realized, and a positive contribution is made to environmental protection and sustainable development. The anti-cracking reinforcing agent is suitable for the engineering fields of buildings, roads and the like, and provides a high-performance, economical and feasible solution for construction.
本发明公开了一种具有微膨胀特性的抗裂增强剂，其组分及质量份数为：锂渣65份‑90份、粉煤灰15份～35份、钢渣微粉10份～20份、矿粉10份～30份、聚羧酸减水剂0.5份～2份、碳酸钠1份～3份、氢氧化钠0.8份～2.4份。本发明利用工业副产品、减水剂、碱激发剂制备了一种具有潜在微膨胀特性的抗裂增强剂干混料，旨在改善水泥基材料的力学性能和收缩性能。同时，通过资源化利用工业固废，不仅减少了其对环境的破坏，还实现了资源的循环利用，为环境保护和可持续发展做出了积极贡献。该抗裂增强剂适用于建筑、道路等工程领域，为施工提供了高性能且经济可行的解决方案。
