    EPOXY RESIN COMPOSITION FOR CONCRETE, MOLDED EPOXY RESIN BODY, AND METHOD FOR PRODUCING MOLDED EPOXY RESIN BODY

    New search for: ITO GENTA
    New search for: KONO HIROYUKI

    To provide an epoxy resin composition for concrete which has low cure shrinkage, is excellent in filling (flowability) and curing properties, is excellent in load resistance (compressive strength), and can form a molded body which is thick but hardly cracks.SOLUTION: An epoxy resin composition for concrete comprises an epoxy resin (A), a reactive diluent having two or more glycidyl groups (B), an extender pigment (C), and an alkylene polyamine (D) having no ether group, wherein: a pigment volume concentration (PVC) is 40% or more; and viscosity measured with a type-B viscometer at 23°C is 5 to 50 Pa_s.SELECTED DRAWING: None

    【課題】低硬化収縮率であり、充填性（流動性）および硬化性に優れるエポキシ樹脂組成物であって、耐荷重性（圧縮強度）に優れ、厚くてもクラックが生じ難い成形体を形成することができるコンクリート用エポキシ樹脂組成物を提供すること。【解決手段】エポキシ樹脂（Ａ）、グリシジル基を２つ以上有する反応性希釈剤（Ｂ）、体質顔料（Ｃ）、および、エーテル基を有さないアルキレンポリアミン（Ｄ）を含有し、顔料容積濃度（ＰＶＣ）が４０％以上であり、Ｂ型粘度計を用いて測定した２３℃における粘度が５～５０Ｐａ・ｓである、コンクリート用エポキシ樹脂組成物。【選択図】なし
