The invention discloses a cement-based composite material crack self-repairing method cooperating with utilization of solid waste and carbon dioxide, and belongs to the technical field of building materials. Solid waste is used as a raw material, and after being sealed and soaked, the solid waste is properly pretreated to prepare the self-repairing agent with a certain particle size; the self-repairing agent is added into an existing cement-based material system, short fibers are added in a matched mode, and the cement-based composite material is prepared. The short fibers are added to limit the crack width of the cement-based composite material, after the cement-based composite material cracks, the embedded self-repairing agent reacts with carbon dioxide to achieve crack self-repairing, and the whole process is simple, economical and environmentally friendly. The problem that in the prior art, the self-repairing capacity is weakened due to the fact that CaO is insufficient is solved, a technical path is provided for high-value utilization of industrial solid waste, and the problem of recycling of a large amount of solid waste is solved.
本发明公开了一种协同固体废弃物与二氧化碳利用的水泥基复合材料裂缝自修复方法，属于建筑材料技术领域。本发明以固体废弃物为原料，经密封浸泡处理后，对其进行适宜的预处理制备得到一定粒径的自修复剂；将所述自修复剂加入至既有的水泥基材料体系中，配合加入短纤维，制备水泥基复合材料；本发明通过加入短纤维来限制水泥基复合材料裂缝的宽度，而当水泥基复合材料发生开裂后，所嵌入的自修复剂与二氧化碳发生反应实现裂缝自修复，整个过程简单、经济且环保。本发明不仅解决了现有技术中由于CaO成分不足所导致的自修复能力减弱的问题，还为工业固体废弃物的高价值利用提供了技术路径，解决了大宗固废的回收利用问题。
