SOLID CEMENT ADMIXTURE
To provide a solid cement admixture excellent in workability as a solid and in developing dispersibility.SOLUTION: The solid cement admixture characterized by containing a polycarboxylic acid based copolymer in a range of 10 to 500 weight% relative to 100 weight% of a cellulose based carrier, is characterized in that the water absorption of the cellulose based carrier represented by [(weight (g) after hydration treatment-weight (g) before hydration treatment)/weight (g) before hydration treatment]×100 is not lower than 150%.SELECTED DRAWING: None
【課題】本発明によれば、固形状としての良好な作業性と、分散性の発現に優れる固形状セメント混和剤を提供することができる。【解決手段】セルロース系担体１００重量％に対し、ポリカルボン酸系共重合体を１０〜５００重量％の範囲で含むことを特徴とする固形状セメント混和剤であって、該セルロース系担体は、（加水処理後の重量（ｇ）−加水処理前の重量（ｇ））／加水処理前の重量（ｇ）×１００で示される吸水率が１５０％以上であることを特徴とする固形状セメント混和剤。【選択図】なし
