MANUFACTURING METHOD OF HYDRATED MATRIX
PROBLEM TO BE SOLVED: To provide a manufacturing method of hydrated matrix using steel slag as a raw material and having high density and excellent in quality such as strength effectively at low cost.SOLUTION: Hydrated matrix having wet specific gravity of 2.60 to 2.90 is provided by adding water of 70 kg/mor more to a raw material of which total amount of an aggregate consists of steel slag and containing blast furnace slag fine powder and/or cement as a binding material and mixing them to prepare a mixture having percentage of the steel slag of 65 mass% or more, moisture content of 2 to 8 mass% and slump value of 2 cm or less, inputting the mixture into a mold and conducting vibration compaction or vibration compression compaction, molding by an instant demolding method for demolding and then curing it.SELECTED DRAWING: None
【課題】原料に鉄鋼スラグを用いた水和固化体であって、高比重で且つ強度などの品質が優れた水和固化体を効率的且つ安価に製造することができる製造方法を提供する。【解決手段】骨材の全量が製鋼スラグからなり、結合材として高炉スラグ微粉末及び／又はセメントを含む原料に、７０ｋｇ／ｍ３以上の水を加えて混練し、製鋼スラグの割合が６５質量％以上、水分が２〜８質量％、スランプ値が２ｃｍ以下の混練物とし、この混練物を型枠に投入して振動締め固め又は振動加圧締め固めを行った後、脱型する即時脱型法で成型し、その後硬化させて湿潤比重が２．６０〜２．９０の水和固化体を得る。【選択図】なし
