ENVIRONMENTALLY FRIENDLY COMPOSITION, AND ENVIRONMENTALLY FRIENDLY HARDENED BODY
To provide a composition with extremely little carbon emission, capable of improving strength development and of abating an Absanden phenomenon and dry shrinkage.SOLUTION: An environmentally friendly composition (1) comprising blast furnace slag fine powder, 0.5 to 10 parts of a stimulant relative to 100 parts of the blast furnace slag fine powder, a binder, and fine aggregate, is characterized in that the proportion of slowly cooled blast furnace fine aggregate per 100 parts of the fine aggregate is not less than 30 parts. There are provided an environmentally friendly composition (2) according to (1), in which the portion of the slowly cooled blast furnace slag fine aggregate passing through a sieve of 0.1 mm mesh opening per 100 parts of the slowly cooled blast furnace fine aggregate passing through a sieve of 0.15 mm mesh opening is not less than 30 parts, and an environmentally friendly composition (3) according to (1) or (2), with the eluent from the fine aggregate therein having a pH of not lower than 10.SELECTED DRAWING: None
【課題】本発明は、炭素排出量が極めて小さい組成物であって、強度発現性を改善でき、アブサンデン現象も抑制でき、乾燥収縮も抑制できる組成物を提供する。【解決手段】（１）高炉スラグ微粉末１００部に対して、刺激材０．５〜１０部を含む結合材と細骨材を含み、細骨材１００部中に占める高炉徐冷スラグ細骨材の割合が３０部以上であることを特徴とする環境配慮型組成物であり、（２）高炉徐冷スラグ細骨材の０．１５ｍｍ篩通過分１００部中に占める０．１ｍｍ篩通過分の割合が３０部以上である（１）の環境配慮型組成物であり、（３）細骨材からの溶出液のｐＨが１０以上である（１）又は（２）の環境配慮型組成物である。【選択図】なし
