HYDRAULIC COMPOSITION, ONE-COMPONENT PLASTIC GROUT, AND CONSTRUCTION METHOD FOR FILLING ONE-COMPONENT PLASTIC GROUT
To provide a hydraulic composition to be used for preparing a one-component plastic grout that shows relatively high flowability right after mixing even when an ambient temperature is relatively low, and that can show plasticity suitable for limited injection relatively for a short period after the mixing.SOLUTION: A hydraulic composition according to this invention comprises a blast furnace slag powder, an alkaline material powder, a bentonite powder, and a dispersant powder. The amount of the alkaline material powder contained based on 100 pts.mass of the blast furnace slag powder is 60 pts.mass or less. The dispersant powder is a condensed phosphate powder, wherein when 1% of the dispersant powder is put in an aqueous solution, pH is 7.5 or more.SELECTED DRAWING: None
【課題】本発明は、外気温が比較的低温の場合でも、混練直後に比較的高い流動性を示し、かつ、混練後比較的短時間で限定注入に適した可塑性を示すことができる一液型可塑性注入材を調製するために用いる水硬性材料等を提供する。【解決手段】本発明に係る水硬性材料は、高炉スラグ粉末、アルカリ性材料粉末、ベントナイト粉末、及び分散剤粉末を含み、前記高炉スラグ粉末１００質量部に対する前記アルカリ性材料粉末の配合量が６０質量部以下であり、前記分散剤粉末は、１％水溶液でのｐＨが７．５以上である縮合リン酸塩粉末である。【選択図】 なし
