CRACK REPAIRING MATERIAL AND CRACK REPAIRING METHOD
To provide a crack repairing material and a crack repairing method excellent in workability and causing no environmental problem even if the crack repairing material as a filler flows out.SOLUTION: A crack repairing material containing shell powder, a metabolic microorganism generating carbonate ions by metabolism, and a calcium source is injected into a crack of a cement structure to repair cracks, and before injecting the repairing material, the cracked parts are washed with water containing a pretreatment microorganism generating carbonate ions by metabolism.SELECTED DRAWING: Figure 1
【課題】施工性に優れるとともに、充填材であるひび割れ補修材が流出しても環境問題が生じることのない、ひび割れ補修材とひび割れ補修方法とを提供する。【解決手段】貝殻の粉末と、代謝により炭酸イオンを発生する代謝用微生物と、カルシウム源と、を含有するひび割れ補修材を、セメント系構造物のひび割れに注入して補修するとともに、前記補修材を注入する前に、前記ひび割れ箇所を、代謝により炭酸イオンを発生する前処理用微生物を含む水で水洗いする工程を設けた。【選択図】図１
