Preparation method of concrete self-repairing agent
The invention provides a preparation method of a concrete self-repairing agent, which comprises the following steps: taking expanded perlite as a microbial carrier, carrying out fermentation culture to prepare a spore suspension and a denitrifying bacterium suspension, putting the expanded perlite into a vacuum cylinder, carrying out vacuum treatment until the vacuum degree is-0.06 MPa, and sucking prepared bacterium liquid through a pressure relief ball valve to obtain bacterium-loaded perlite; placing the bacterium-loaded perlite in an air dry oven at 40 DEG C, and drying to constant weight; putting the dried fungus-loaded perlite into a stirrer, uniformly spraying a nutrient layer solution on the surface of the fungus-loaded perlite, starting an air compressor and the stirrer at the same time, stirring, curing and maintaining for 1 day, putting into a blast drying box at 40 DEG C, and drying to constant weight; and uniformly spraying a protective layer solution on the surface of the concrete through the same steps, and drying to obtain the concrete self-repairing agent.
本发明提供了一种混凝土自修复剂的制备方法，该修复剂以膨胀珍珠岩为微生物载体，发酵培养制得芽孢悬浊液和反硝化菌悬浊液，将膨胀珍珠岩置于真空筒中，真空至真空度为‑0.06MPa停止，经泄压球阀吸入制备好的菌液，得到载菌珍珠岩；将载菌珍珠岩置于40℃鼓风干燥箱中，烘干至恒重；烘干后的载菌珍珠岩放入搅拌机中，均匀在其表面喷洒营养层溶液，同时开启空气压缩机和搅拌机，搅拌后固化养护1d，置于40℃鼓风干燥箱中，烘干至恒重；同样的步骤均匀在其表面喷洒保护层溶液，烘干后得到混凝土自修复剂。
