HYDRAULIC EPOXY RESIN MORTAR COMPOSITION FOR FLOOR FINISHING AND CONSTRUCTION METHOD THEREOF
To provide a hydraulic epoxy resin mortar composition for floor finishing, giving a smooth finish and having an excellent impact resistance even when base concrete has unevenness or locally has convex portions, and a construction method thereof.SOLUTION: The present invention provides a hydraulic epoxy resin mortar composition for floor finishing that comprises a hydraulic cement, an aggregate, an epoxy resin, an aqueous epoxy resin curing agent and a non-aqueous epoxy resin curing agent, and a construction method thereof, in which the epoxy resin includes a urethane-modified epoxy resin, a weight ratio of water to the hydraulic cement is 0.1 to 0.3, a weight of a resin solid content is 35 to 55% to a weight of the entire composition containing water when the epoxy resin is synthesized by adding reactive aqueous and non-aqueous epoxy resin curing agents to the epoxy resin, and the aggregate is 20 to 50 pts.mass per 100 pts.mass of the entire composition.SELECTED DRAWING: None
【課題】下地コンクリートに不陸が有る場合や、局所的に凸部が存在する場合であっても、良好な仕上がりとなり、また耐衝撃性に優れる床仕上げ用水硬性エポキシ樹脂モルタル組成物及びその施工方法を提供する。【解決手段】水硬性セメントと骨材とエポキシ樹脂と水系エポキシ樹脂硬化剤と非水系エポキシ樹脂硬化剤とを含む床仕上げ用水硬性エポキシ樹脂モルタル組成物であって、エポキシ樹脂はウレタン変性エポキシ樹脂を含み、水硬性セメントに対する水の重量比が０．１～０．３であり、エポキシ樹脂に該エポキシ樹脂と反応する水系エポキシ樹脂硬化剤と非水系エポキシ樹脂硬化剤を加えたものを樹脂とした場合の樹脂固形分重量が水を含んだ全組成物の重量に対して３５～５５％であり、骨材は組成物全体１００重量部に対して２０～５０重量部であることを特徴とする床仕上げ用水硬性エポキシ樹脂モルタル組成物及びこの施工方法である。【選択図】なし
