Building waterproof self-repairing material and preparation method thereof
The invention discloses a building waterproof self-repairing material and a preparation method thereof, and the building waterproof self-repairing material comprises the following raw materials by mass: 10%-15% of cement, 15%-25% of silica fume, 10%-15% of fly ash, 15%-20% of slag, 1%-5% of nano-silica, 1%-3% of nano-clay, 1%-3% of a clay regulator, and 1%-3% of nano-cellulose. The concrete is prepared from the following components in percentage by weight: 2%-5% of hydrogel, 0.3%-1% of a pore-foaming agent, 0.3%-0.5% of a polycarboxylic acid water reducing agent, 0.3%-0.5% of a flocculating agent, 0.3%-0.5% of an air entraining agent, 3%-5% of an alkali activator, 0.01%-0.03% of microorganisms and the balance of water. The building waterproof self-repairing material can prevent water from permeating into a concrete building when used in the field of daily buildings, can perform self-repairing under the condition that water permeates into the concrete building, and has the advantages of good stability, early strength, rapid hardening and excellent mechanical properties.
本发明公开了一种建筑防水自修复材料及其制备方法，该建筑防水自修复材料包括以下质量百分数的原材料：水泥10％‑15％，硅灰15％‑25％，粉煤灰10％‑15％，矿渣15％‑20％，纳米二氧化硅1％‑5％，纳米黏土1％‑3％，黏土调节剂1％‑3％，纳米纤维素1％‑3％，水凝胶2％‑5％，致孔剂0.3‑1％，聚羧酸减水剂0.3％‑0.5％，絮凝剂0.3％‑0.5％，引气剂0.3％‑0.5％，碱性激发剂3％‑5％，微生物0.01％‑0.03％，余量为水。本发明所述建筑防水自修复材料在日常建筑领域使用中能够防止水渗透进混凝土建筑内，并能在混凝土建筑物内在已经渗水的情况下，进行自修复，具有稳定性好，早强快硬和力学性能优良的优点。
