Microbial gelling repair material, microbial gelling self-repair material as well as preparation method and application of microbial gelling repair material and microbial gelling self-repair material
The invention relates to a microbial gelling repairing material, a microbial gelling self-repairing material and a preparation method and application thereof.The microbial gelling repairing material is obtained by conducting primary stirring and mixing on modified fibers loaded with microorganisms, part of gelling materials and part of water, then adding the remaining gelling materials, the remaining water and fine aggregate and conducting secondary stirring and mixing. Or the modified fiber loaded with microorganisms, part of the gelling material and part of the water are subjected to primary stirring and mixing, then the remaining gelling material, the remaining water, the fine aggregate and the coarse aggregate are added, secondary stirring and mixing are conducted, the microorganism gelling self-repairing material is obtained, and the microorganisms are selected from any one of sporosarcina pasteurii or bacillus sphaericus; the modified fibers in the modified fibers loaded with the microorganisms are obtained through alkali treatment and electrophoretic deposition method treatment. Compared with the prior art, the preparation method disclosed by the invention is simple and easy to implement, and the product has relatively high compressive strength, crack self-repairing capability and impermeability.
本发明涉及一种微生物胶凝修复材料、微生物胶凝自修复材料及制备方法与应用，将负载有微生物的改性纤维、部分胶凝材料、部分水进行一次搅拌混合，再加入剩余胶凝材料、剩余水、细集料进行二次搅拌混合，得到微生物胶凝修复材料，或将负载有微生物的改性纤维、部分胶凝材料、部分水进行一次搅拌混合，再加入剩余胶凝材料、剩余水、细集料、粗骨料进行二次搅拌混合得到微生物胶凝自修复材料，其中，所述微生物选自巴氏生孢八叠球菌或球形芽孢杆菌中的任意一种；所述负载有微生物的改性纤维中的改性纤维通过碱处理和电泳沉积法处理得到。与现有技术相比，本发明的制备方法简单易实施，且产物均具有较高的抗强压强度、自修复裂缝能力、抗渗性。
