REPAIR MATERIAL FOR CONCRETE STRUCTURE AND REPAIRING METHOD OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a repair material which can easily and certainly prevent peeling of concrete, can be used for a fire resistive structure and has waterproofing performance, and a repairing method.SOLUTION: The repair material is provided that is used for repairing an existing concrete structure and comprises: a composition containing sodium silicate and/or lithium silicate, a filler and a curing agent; and a laminate in which a plurality of sheet-like members are laminated. Each of the plurality of sheet-like members contains glass fiber, and one of the plurality of sheet-like members has a larger tensile strength than those of other sheet-like members.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、珪酸ナトリウム及び／又は珪酸リチウム、フィラー及び硬化剤を含む組成物と、複数のシート状部材を積層した積層体とを備え、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
