Basalt fiber anti-cracking waterproof agent for concrete and preparation method thereof
The invention discloses a basalt fiber anti-cracking waterproof agent for concrete and a preparation method thereof. The basalt fiber anti-cracking waterproof agent is prepared by mixing an expandingagent, basalt fibers, a hydration heat inhibitor and a waterproof component according to a certain mass percentage. The basalt fiber anti-cracking waterproof agent is prepared from the following components in percentage by mass: 65-80% of the expanding agent, 5-10% of the basalt fibers, 5 to 10% of the hydration heat inhibitor, and 10-15% of the waterproof component. Compared with the prior art, the hydration temperature rise rate of the concrete is reduced, the tensile strength of the concrete is improved by using the basalt fibers, and the durability, crack resistance and seepage resistanceof the concrete are enhanced. The anti-cracking waterproof capability is strong, and the performance is stable. The basalt fibers are typical silicate fibers, have natural compatibility with a concrete matrix, do not influence the working performance of a concrete mixture, and have good adaptability to Portland cement and ordinary Portland cement.
本发明公开了一种混凝土用玄武岩纤维抗裂防水剂及其制备方法，所述玄武岩纤维抗裂防水剂由膨胀剂、玄武岩纤维、水化热抑制剂、防水组分按照一定的质量百分比混合而成,所述玄武岩纤维抗裂防水剂包含的组分和各组分的质量分数为膨胀剂65～80％、玄武岩纤5～10％、水化热抑制剂5～10％；防水组分10～15％。与现有技术相比，本发明降低了混凝土水化温升速率，使用玄武岩纤维提高了混凝土的抗拉强度，增强了混泥土的耐久性和抗裂防渗性能。抗裂防水能力强、性能稳定，玄武岩纤维是典型的硅酸盐纤维，与混凝土基体具有天然的相容性，不影响混凝土拌合物工作性能，对硅酸盐水泥、普通硅酸盐水泥都有良好的适应性。
