REPAIRING MATERIAL OF CONCRETE STRUCTURE, AND REPAIRING METHOD OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a repairing material capable of easily and surely preventing exfoliation of concrete, usable for a fireproof construction, and having also water-resistant performance, and a repairing method.SOLUTION: A repairing material for a concrete structure as a repairing material used for repairing an existing concrete structure is such that: there is included a laminate made by laminating a composition which contains sodium silicate, potassium silicate, lithium silicate or their mixture, alkyl siliconate, and a hardening agent, and a plurality of sheet-like members; the sheet-like member comprises fiber glass; and one of the plurality of sheet-like members has a tension strength larger than that of the other sheet-like member.SELECTED DRAWING: Figure 1
【課題】簡便かつ確実にコンクリートの剥落を防止することができ、耐火構造物にも使用可能であり、耐水性能を兼ね備えた補修材料及び補修方法を提供することを目的とする。【解決手段】既設のコンクリート構造物の補修に用いられる補修材料であって、珪酸ナトリウム、珪酸カリウム、珪酸リチウム又はこれらの混合物と、アルキルシリコネートと、硬化剤とを含む組成物及び複数のシート状部材を積層した積層体を備え、前記シート状部材は、いずれもガラス繊維を含んで構成され、前記複数のシート状部材のうちのひとつが、他のシート部材よりも引張強度が大きいことを特徴とするコンクリート構造物の補修材料。【選択図】図１
