Foam fiber self-repairing concrete and preparation method thereof
The invention discloses foam fiber self-repairing concrete and a preparation method thereof, the foam fiber self-repairing concrete comprises a concrete member, concrete used by the concrete member is foam concrete, and a sodium silicate repairing agent, a capillary crystalline material and polyvinyl alcohol fibers are distributed in the concrete member. The preparation method comprises the following steps: preparing the sodium silicate repairing agent, preparing concrete slurry, metering and foaming, mixing and stirring, and pouring and curing. By compounding the sodium silicate self-repairing agent and the capillary crystalline material, the current repairing agent material is optimized, and the self-repairing effect of the repairing agent is improved; by adding the polyvinyl alcohol fiber and the composite self-repairing agent, the problems of low tensile strength, fracture resistance and compressive strength and easy cracking of the foam concrete are solved in a targeted manner, so that the structural safety, durability and economical efficiency of the concrete are improved.
本发明公开了一种泡沫纤维自修复混凝土及其制备方法，所述泡沫纤维自修复混凝土包括混凝土构件，所述混凝土构件所使用的混凝土为泡沫混凝土，所述混凝土构件内分布有硅酸钠修复剂、渗透结晶材料和聚乙烯醇纤维。所述制备方法包括：制备硅酸钠修复剂，配制混凝土浆料，计量发泡，混合搅拌，浇筑养护。本发明通过硅酸钠自修复剂和渗透结晶材料复合使用，优化当前的修复剂材料，提高修复剂的自修复效果；通过加入聚乙烯醇纤维和复合型自修复剂，针对性解决泡沫混凝土的抗拉、抗折、抗压强度低和易开裂的问题，从而提高混凝土的结构的安全性、耐久性和经济性。
