Recycled concrete with self-repairing capability and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses recycled concrete with self-repairing capacity and a preparation method of the recycled concrete. The invention discloses recycled concrete with self-repairing capability. The recycled concrete is prepared from the following components in parts by weight: 1200 to 1300 parts of recycled aggregate, 900 to 1100 parts of cement, 700 to 800 parts of quartz sand, 100 to 140 parts of silica fume, 80 to 100 parts of fly ash, 5 to 10 parts of a water reducing agent, 1.2 to 2.4 parts of a microbial repairing agent, 20 to 28 parts of an expanding agent and 400 to 450 parts of water, the microbial remediation agent is formed by mixing a bacillus pasteurii suspension liquid and a bacillus amyloliquefaciens liquid according to the weight ratio of (0.5-1.5): (0.5-1.5); the expanding agent consists of calcium salt and sorbitol in a weight ratio of 9: (1-3). According to the technical scheme provided by the invention, the prepared recycled concrete is relatively excellent in chloride ion penetration resistance and dry shrinkage value, and good in anti-aging effect.
本申请涉及建筑材料的技术领域，具体公开了一种具有自修复能力的再生混凝土及其制备方法。本申请公开的一种具有自修复能力的再生混凝土，包括以下重量份的组分：再生骨料1200‑1300份、水泥900‑1100份、石英砂700‑800份、硅灰100‑140份、粉煤灰80‑100份、减水剂5‑10份、微生物修复剂1.2‑2.4份、膨胀剂20‑28份、水400‑450份；微生物修复剂由重量比为0.5‑1.5：0.5‑1.5的巴氏芽孢杆菌悬浮液和解淀粉芽孢杆菌菌液混合组成；膨胀剂由重量比为9：1‑3的钙盐与山梨醇组成。利用本申请提供的技术方案，制备的再生混凝土的抗氯离子渗透性能以及干缩收缩值的性能较优，且耐老化效果好。
