STEEL SLAG GRAIN, STEEL SLAG, AND METHOD FOR PRODUCING STEEL SLAG GRAIN
PROBLEM TO BE SOLVED: To provide a steel slag grain easy in handling and storage at a yard or the like using equipment such as a belt conveyor and a track, in which hydration expansion is hard to occur, and being suitably usable as a fine aggregate, steel slag containing the steel slag grain, and a method for producing the same.SOLUTION: Provided is a steel slag grain having a surface shape in which a part of a closed curved surface is made into a fracture face, and 10 to 90% of the surface area is composed of curved face.SELECTED DRAWING: None
【課題】ベルトコンベア及びトラックなどの設備を用いたハンドリング並びにヤードなどでの保管が容易であって、水和膨張し難く、細骨材として好適に使用することができる製鋼スラグ粒子、該製鋼スラグ粒子を含む製鋼スラグ、並びにその製造方法を提供する。【解決手段】製鋼スラグ粒子を、閉曲面の一部が破断面となる表面形状を有し、表面積の１０〜９０％が曲面で構成されるものとする。【選択図】なし
