Microbial self-repairing concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses microbial self-repairing concrete, which comprises the following components in parts by weight: 860-980 parts of coarse aggregate, 630-760 parts of fine aggregate, 320-360 parts of cement, 40-55 parts of silica fume, 140-180 parts of mineral powder, 140-160 parts of water, 7-9 parts of a sodium sulfamate water reducing agent, 11-13 parts of urea, 13-15 parts of calcium chloride, and 85-100 parts of a carrier, which is loaded with a crack repairing agent and has a coated surface, wherein the crack repairing agent is anaerobic bacillus pasteurii liquid. The microbial self-repairing concrete has the advantage that the concrete can be self-repaired after cracking in an anoxic environment.
本申请涉及混凝土的领域，具体公开了一种微生物自修复混凝土，一种微生物自修复混凝土包括以下重量份的组分：粗骨料860‑980份，细骨料630‑760份，水泥320‑360份，微硅粉40‑55份，矿粉140‑180份，水140‑160份，氨基磺酸钠减水剂7‑9份，尿素11‑13份，氯化钙13‑15份，载有裂缝修复剂且包裹表面的载体85‑100份，其中裂缝修复剂为厌氧的巴氏芽孢杆菌液。本申请的一种微生物自修复混凝土具有能在缺氧环境下的混凝土裂缝后能够自修复优点。
