Concrete crack self-repairing emulsion and preparation method thereof
The invention discloses a concrete crack self-repairing emulsion and a preparation method thereof. The concrete crack self-repairing emulsion is prepared from, by weight, 15 to 110 parts of a Bacillusmucilaginosus mixed bacterium liquid, 20 to 50 parts of expanded perlite, 15 to 25 parts of a yeast extract mixed solution, 800 to 1100 parts of stones, 350 to 650 parts of quartz sands, 15 to 25 parts of silica fume, 1 to 3 parts of a polypropylene fiber, 4 to 6 parts of a water reducing agent, 30 to 50 parts of sodium citrate, 15 to 25 parts of choline chloride, 10 to 20 parts of KAl(SO4)2. 12H2O, 10 to 20 parts of Na2SiO3. 9H2O, 10 to 20 parts of powdery Ca(OH)2, 280 to 320 parts of potassium magnesium phosphate cement, 25 to 35 parts of a styrene-acrylic emulsion and 430 to 450 parts of water. The Bacillus mucilaginosus can generate a metalloenzyme taking zinc as an active center, and the metalloenzyme generated by the Bacillus mucilaginosus can accelerate the conversion process between CO2 and HCO3<->, so that the CaCO3 deposition rate is increased, and the concrete crack repairing rate is increased. The Bacillus mucilaginosus is matched with a kiln firing method to process the expanded perlite , so that the adsorption capacity of the processed expanded perlite is greatly improved, the adsorption capacity and survival quantity of the Bacillus mucilaginosus are greatly improved, and the self-repairing effect is effectively improved.
本发明公开一种混凝土裂缝自修复乳液及其制备方法，由以下重量比的原料组成：胶质芽孢杆菌混合菌液15‑110份、膨胀珍珠岩20‑50份，酵母膏混合溶液15‑25份，石子800‑1100份，石英砂350‑650份，硅灰15‑25份，聚丙烯纤维1‑3份，减水剂4‑6份，柠檬酸钠30‑50份，氯化胆碱15‑25份，KAl(SO4)2·12H2O10‑20份，Na2SiO3·9H2O10‑20份，粉状Ca(OH)210‑20份，磷酸钾镁水泥280‑320份、苯丙乳液25‑35份、水430‑450份。本发明的胶质芽孢杆菌可以产生一种以锌为活性中心的金属酶，胶质芽孢杆菌产生的金属酶可加速CO2与HCO3‑之间的转化过程，从而提高CaCO3沉积速率，提高修复混凝土裂缝的速率。胶质芽孢杆菌配合采用窑烧法加工膨胀珍珠岩，加工后的膨胀珍珠岩吸附能力大大提高，胶质芽孢杆菌吸附量和存活数量大大提高、有效提高自修复效果。
