REPAIR MATERIAL AND REPAIR METHOD
PROBLEM TO BE SOLVED: To provide a repair material and repair method capable of repairing a cement-based structure quickly by a simple process.SOLUTION: This invention relates to a repair material used for repairing the cement-based structures. The repair material includes an anaerobic microbe and a water-soluble polymer. The water-soluble polymer has functional groups. The functional group is cross-linked by calcium originated from the cement-based structure and thereby, the water-soluble polymer gelates. On the other hand, the anaerobic microbe generates carbon dioxide by anaerobic metabolism even in the repair material, and calcium carbonate separates out by reaction of the carbon dioxide with the calcium ion. Accordingly, the gel film of the repair material becomes a dense film having high mechanical strength by separating out of calcium carbonate therein.SELECTED DRAWING: Figure 1
【課題】セメント系構造物を迅速かつ簡易な方法で補修可能な補修材料及び補修方法を提供する。【解決手段】本発明はセメント系構造物の補修に用いられる補修材料であって、この補修材料は嫌気性微生物と、水溶性ポリマーとを含む。水溶性ポリマーは官能基を有し、この官能基がセメント系構造物由来のカルシウムで架橋され、水溶性ポリマーがゲル化する。他方、嫌気性微生物は嫌気代謝により補修材料中であっても二酸化炭素を発生させ、この二酸化炭素がカルシウムイオンと反応して炭酸カルシウムが析出する。従って、補修材料のゲル膜はその内部に炭酸カルシウムが析出して緻密で機械的強度が高い膜となる。【選択図】図１
