Repairing agent and method for repairing concrete cracks through ion-assisted staphylococcus epidermidis induced carbonate deposition
The invention discloses a repairing agent and method for repairing concrete cracks by ion-assisted staphylococcus epidermidis induced carbonate deposition, staphylococcus epidermidis is used for repairing the concrete cracks, and a metal cation doping method is adopted for improving a culture medium of staphylococcus epidermidis. The staphylococcus epidermidis with the improved culture medium is used as a microbial repairing agent to repair concrete cracks; ni < 2 + > ions or Ca < 2 + > ions are added into a culture medium of the staphylococcus epidermidis in an improved manner, and the adding concentration is 5-55 [mu] mol/L. According to the method, the ion type and concentration and the repairing effect on cracks with different widths are studied, the effect of multiple indexes on the culture medium is studied, the improved culture medium more suitable for repairing the concrete cracks by inducing carbonate deposition through staphylococcus epidermidis is obtained, and a more effective concrete crack repairing scheme is formed.
本发明公开了一种离子辅助表皮葡萄球菌诱导碳酸盐沉积修复混凝土裂缝的修复剂及方法，采用表皮葡萄球菌用于混凝土裂缝修复，表皮葡萄球菌采用金属阳离子掺加法对其培养基进行改进，将培养基改进后的表皮葡萄球菌作为微生物修复剂对混凝土裂缝进行修复；向表皮葡萄球菌的培养基中改进添加Ni2+离子或Ca2+离子，添加浓度为5μmol/L‑55μmol/L。本发明研究了离子类型和浓度及对不同宽度裂缝的修复效果，通过多种指标对培养基的效果进行研究，获得更适合表皮葡萄球菌诱导碳酸盐沉积修复混凝土裂缝的改进培养基，形成更有效的混凝土裂缝修复方案。
