    METHOD OF MOLDING PRECAST CONCRETE, HYDRAULIC COMPOSITION TO BE USED IN THE METHOD, AND PRECAST CONCRETE

    New search for: FURUTA AKIHIRO

    To provide a method of molding precast concrete with improved beautiful surface appearance.SOLUTION: The method of molding precast concrete comprises a hydraulic composition production step of mixing hydraulic powder, aggregate and water to produce a hydraulic composition, and a vibration step of filling a concrete form with the hydraulic composition and vibration-molding the hydraulic composition. In the hydraulic composition production step, 0.0001 to 0.01 pt.mass of an oxyalkylene modified rosin derivative is mixed with 100 pts.mass of the hydraulic powder.SELECTED DRAWING: None

    【課題】表面美観性が改善されたプレキャストコンクリートの成形方法を提供する。【解決手段】水硬性粉体、骨材及び水を混合して水硬性組成物を製造する水硬性組成物製造工程と、前記水硬性組成物を型枠に充填して振動成形する振動工程と、を有し、前記水硬性組成物製造工程において、前記水硬性粉体１００質量部に対して０．０００１～０．０１質量部のオキシアルキレン変性ロジン誘導体を混合することを特徴とするプレキャストコンクリートの成形方法。【選択図】なし
