ESTIMATION METHOD OF SLAG WATER IMMERSION EXPANSION RATIO, STEEL SLAG FOR ROAD BUILDING AND REINFORCED ROADBED MATERIAL AND ITS MANUFACTURING METHOD
To propose a simple and accurate method for estimating the water immersion expansion ratio of slag, a reinforced roadbed material that does not cause reverse fault type failure, and its manufacturing method.SOLUTION: There is provided a method for estimating the water immersion expansion ratio of steel slag for road building, in which the water immersion expansion test of the slag is performed to obtain a water immersion expansion ratio of the slag at a predetermined measurement temperature and measurement time, and the water immersion expansion ratio can be obtained in a predetermined estimated time when the water immersion expansion test of the slag is performed at a predetermined estimated temperature, and reinforced roadbed material made of a mixture of cement and slag is composed of materials whose estimated water immersion expansion ratio (%) of slag is lower than the strain rate (%) that brings about compressive failure of reinforced roadbed material in a compression test of reinforced roadbed material after cement curing.SELECTED DRAWING: Figure 1
【課題】簡便に精度よく推定する、スラグの水浸膨張比推定方法および逆断層型破壊を起こすことのない強化路盤材およびその製造方法を提案する。【解決手段】道路用鉄鋼スラグの水浸膨張比の推定方法であって、前記スラグの水浸膨張試験を行って、所定の測定温度および測定時間における前記スラグの水浸膨張比を得て、所定の推定温度で前記スラグの水浸膨張試験を行った場合に所定の推定時間で前記水浸膨張比が得られるように推定する、スラグの水浸膨張比推定方法である。セメントとスラグとの混合物からなる強化路盤材を、推定したスラグの水浸膨張比（％）が、セメント養生後における強化路盤材の圧縮試験における強化路盤材の圧縮破壊に至る歪み率（％）よりも下回るもので構成する。【選択図】図１
