ADMIXTURE FOR LONG DISTANCE TRANSPORTATION AND CEMENT COMPOSITION
To provide an admixture for concrete adding high fluidity and moderate viscosity to concrete and maintaining these properties over long time, and further providing no change on these properties even after pump pressure-feeding.SOLUTION: There is provided an admixture for concrete for long distance transportation containing a polycondensated article containing at least one structural unit (I), at least one structural unit (II) and at least one structural unit (III), and having mass average molecular weight Mw of the polycondensated article containing the structural units (I), (II) and (III) in a range of 3,000 to 50,000.SELECTED DRAWING: None
【課題】コンクリートに高い流動性と適度な粘性を付与すると共にこれらの特性を長時間にわたって維持し、さらにポンプ圧送後にもこれらの特性を変化させないコンクリート用混和剤を提供すること。【解決手段】少なくとも１つの構造単位（Ｉ）と、少なくとも１つの構造単位（ＩＩ）と、少なくとも１つの構造単位（ＩＩＩ）とを有する重縮合物を含み、構造単位（Ｉ）、（ＩＩ）及び（ＩＩＩ）を含有する重縮合物の質量平均分子量Ｍｗが、３，０００〜５０，０００の範囲である、長距離輸送をするためのコンクリート用混和剤。【選択図】なし
