Concrete self-repairing fine aggregate as well as preparation method and application thereof
The invention provides a concrete self-repairing fine aggregate and a preparation method and application thereof, the concrete self-repairing fine aggregate comprises floating beads and a repairing agent, the floating beads are in a porous cavity sphere shape, the repairing agent is carried in cavities of the floating beads, and a coating agent is dehydrated and formed on shells of the floating beads. According to the concrete self-repairing fine aggregate, the floating beads serve as a carrier of the repairing agent, the floating beads are of a cavity sphere structure, cavities of the floating beads are used for storing the repairing agent, the coating agent is used for blocking holes in shells of the floating beads, the repairing agent is prevented from overflowing, and in the using process, when a concrete structure cracks, the repairing agent is prevented from overflowing. The wall shell of the floating bead can be damaged by stress generated by cracking, and then the repairing agent in the cavity is released to repair the crack, so that the purpose of self-repairing is achieved.
本申请提供了混凝土自修复细骨料及其制备方法与应用，混凝土自修复细骨料包括漂珠和修复剂，漂珠呈多孔的空腔球体状，修复剂承载于漂珠的空腔内，包覆剂脱水结膜于漂珠外壳上。本申请提供的混凝土自修复细骨料以漂珠作为修复剂的载体，漂珠其本身结构为空腔球体，漂珠的空腔用于储存修复剂，包覆剂用于封堵漂珠外壳的孔洞，防止修复剂溢出，使用过程中，当混凝土结构发生开裂的情况，开裂所产生的应力会破坏漂珠的壁壳，进而将空腔中的修复剂释放出来，对裂缝进行修复，达到自修复的目的。
