Basalt fiber magnesium anti-cracking agent and preparation method thereof
The invention discloses a basalt fiber magnesium anti-cracking agent and a preparation method thereof, and belongs to the technical field of building material admixtures. The basalt fiber magnesium anti-cracking agent provided by the invention is prepared from the following raw materials in parts by weight: 5 to 15 parts of basalt fiber composite material, 80 to 94 parts of magnesium expanding agent and 1 to 5 parts of alpha-sepiolite, the content of basalt fibers in the basalt fiber composite material is 70-90%; the use amount of the basalt fiber magnesium anti-cracking agent in the concrete is 4-6kg/m < 3 >. According to the basalt fiber magnesium anti-cracking agent disclosed by the invention, a proper amount of anti-cracking agent with a micro-expansion characteristic is doped into concrete, so that the tensile strength, compressive strength, impermeability, freezing resistance and impact resistance of the concrete are remarkably enhanced, and the aims of improving the anti-cracking performance and durability of the concrete at the same time are fulfilled.
本发明公开了一种玄武岩纤维镁质抗裂剂及其制备方法，属于建筑材料外加剂技术领域。本发明的玄武岩纤维镁质抗裂剂，以重量份数计，包括以下原料：玄武岩纤维复合材料5～15份、镁质膨胀剂80～94份和α‑海泡石1～5份；所述玄武岩纤维复合材料中玄武岩纤维的含量为70～90％；所述玄武岩纤维镁质抗裂剂在混凝土中的用量为4～6kg/m3。本发明的玄武岩纤维镁质抗裂剂旨在混凝土中通过掺入适量具有微膨胀特性的抗裂剂，显著增强混凝土抗拉强度、抗压强度、抗渗、抗冻和抗冲击性能，达到同时提高混凝土抗裂性能和耐久性的目的。
