The invention provides a repair-enhanced cement-based capillary crystalline waterproof material and a preparation method thereof, and belongs to the technical field of concrete. The concrete is prepared from the following raw materials in parts by weight: 20-50 parts of cement; 30 to 40 parts of quartz sand; 5-10 parts of silica fume; 2-8 parts of a crystallization precipitant; 1-5 parts of a complexing agent; 2-10 parts of rubber powder; 2-6 parts of nano calcium oxide; 0.5 to 2 parts of cellulose ether; 0.5 to 1 part of calcium formate; 0.5 to 1 part of sodium citrate; and 0.2-2 parts of a water reducing agent. The repair-enhanced cement-based capillary crystalline waterproof material prepared by the invention is added when concrete is mixed, and can form a complete body structure with the concrete, so that the concrete can bear higher hydrostatic pressure, and cracks, fine cracks and wide, long and deep cracks generated in concrete pouring and service stages can be quickly and permanently repaired; meanwhile, the mechanical property of the concrete can be enhanced, and wide application prospects are achieved.
本发明提出了一种修复增强型水泥基渗透结晶防水材料及其制备方法，属于混凝土技术领域。由以下原料按重量份制备而成：水泥20‑50份；石英砂30‑40份；硅灰5‑10份；结晶沉淀剂2‑8份；络合剂1‑5份；胶粉2‑10份；纳米氧化钙2‑6份；纤维素醚0.5‑2份；甲酸钙0.5‑1份；柠檬酸钠0.5‑1份；减水剂0.2‑2份。本发明制得的修复增强型水泥基渗透结晶防水材料在混凝土拌和时加入，可与混凝土形成完整的本体结构，使混凝土承受较高的静水压力，并可以快速、持久的修复混凝土浇筑和服役阶段产生的龟裂纹细小裂缝及宽长深裂缝的修复，同时能够增强混凝土的力学性能，具有广阔的应用前景。
