Basalt fiber high-performance crack inhibitor for concrete
The invention relates to a basalt fiber high-performance crack inhibitor for concrete, which is prepared from the following raw materials in percentage by mass: 25 to 50 percent of basalt chopped fiber, 5 to 10 percent of temperature-inhibiting anti-crack waterproof agent and 40 to 70 percent of high-performance concrete expansive agent. The basalt chopped fibers, the temperature-inhibiting anti-cracking waterproof agent and the high-performance concrete expansive agent are mixed together in proportion to form a gelatinous substance when the concrete is stirred, so that the hydration heat temperature rise rate and the temperature peak value of the concrete can be obviously reduced, the temperature inhibition rate is 18-40% or above, and the temperature-inhibiting anti-cracking waterproof agent and the high-performance concrete expansive agent are uniformly mixed. The basalt chopped fibers effectively improve the tensile strength and impermeability of the concrete and enhance the durability of the concrete, and the crack reduction coefficient of the concrete reaches 70% or above.
本发明涉及一种混凝土用玄武岩纤维高性能阻裂剂，由如下质量百分比的原料组成，玄武岩短切纤维25％～50％，抑温抗裂防水剂5％～10％，高性能混凝土膨胀剂40％～70％。利用玄武岩短切纤维，抑温抗裂防水剂与高性能混凝土膨胀剂三者按比例，在混凝土搅拌时混合在一起呈胶状物质，可以明显降低混凝土水化热温升的速率及温度峰值，抑温率为18％～40％以上，玄武岩短切纤维有效提高混凝土的抗拉强度和抗渗性能，增强了混凝土的耐久性，其裂缝降低系数达到70％以上。
