THICKENER FOR HYDRAULIC COMPOSITION, ONE-COMPONENT TYPE WATER-REDUCING AGENT, AND HYDRAULIC COMPOSITION INCLUDING THEREOF
SOLUTION: To provide a thickener for a hydraulic composition including a water-soluble cellulose ether (A), a defoaming agent (B), and a kind of gums (C).EFFECT: The hydraulic composition excellent in bleeding inhibition can be produced, according to the present invention, by using a one-component type water-reducing agent having stable dispersibility to add a desired amount of a water-soluble cellulose ether while suppressing scattering and the like when adding a little amount of the water-soluble cellulose ether.SELECTED DRAWING: None
【解決手段】（Ａ）水溶性セルロースエーテル、（Ｂ）消泡剤、（Ｃ）ガム類を含む水硬性組成物用増粘剤。【効果】本発明によれば、安定した分散性を有する一剤型減水剤を用いることにより、水溶性セルロースエーテルの少量添加時の飛散等を抑制して所望の水溶性セルロースエーテルが添加されて、ブリーディング抑制等に優れた水硬性組成物を製造することが可能である。【選択図】なし
