To provide a calcium aluminate-based filler that is a new binder exhibiting performance of an aqueous organic resin and performance of an inorganic alumina cement, which enables providing of new aqueous solution.SOLUTION: A calcium aluminate-based filler is composed of an aqueous alumina cement liquid A obtained by adding a blocking material to alumina cement and blocking hydration reaction, and a curing agent (hydraulic reaction initiator) B for releasing the blocking material for blocking the hydration reaction of the aqueous alumina cement liquid, in which the A and the B are separately stored in containers and are mixed and used at the site.SELECTED DRAWING: None 【課題】本発明のカルシウムアルミネート系充填材は水性有機樹脂の性能と無機アルミナセメントの性能を出す新しいバインダーであり、これまでに無い水溶液を提供する。【解決手段】Ａ．アルミナセメントにブロッキング材を添加し、水和反応をブロックした水性アルミナセメント液、及び、Ｂ．前記水性アルミナセメント液の水和反応をブロックしているブロッキング材を解除する硬化剤（水硬反応開始剤）からなり、Ａ及びＢを別々に容器内に収納して現場で混合して利用するようにしたことを特徴とするカルシウムアルミネート系充填材。【選択図】なし
