PROBLEM TO BE SOLVED: To provide a method for producing a solidified body using a dredged soil as a raw material, capable of securing a predetermined hardness in the solidified body even under low curing temperature during a production process.SOLUTION: This invention relates to a method for producing a solidified body, including solidifying a mixture, which comprises 55-60% of a water-containing dredged soil, 19-37% of the binding material, and 4-29% of an aggregate, with their blending amounts expressed by volume, through a hydration reaction by a binding material. When a curing temperature during a solidifying step of the mixture is 5-10°C, a hardness index specified by (BP+2×NP+0.35×FA)/W (where BP is a blending amount (kg) of a blast furnace slag powder per mof the mixture; NP is a blending amount (kg) of a normal Portland cement per mof the mixture; Fa is a blending amount (kg) of a fly ash per mof the mixture; and W is the amount (kg) of water per mof the mixture) is set to 1.8 or more, thereby obtaining the solidified body having compressive strength of 15 N/mmor more after the curing for 28 days.SELECTED DRAWING: None
【課題】原料に浚渫土を用いた固化体の製造方法において、製造過程における養生温度が低い条件においても、所定の固化体強度を確保できる固化体の製造方法を提供する。【解決手段】配合量が容積率で浚渫土（水分を含む）：５５〜６０％、結合材：１９〜３７％、骨材：４〜２９％である混合物を、結合材による水和反応により固化させて固化体を得る固化体の製造方法であって、混合物の固化工程における養生温度が５〜１０℃となる場合に、（ＢＰ＋２×ＮＰ＋０．３５×ＦＡ）／Ｗ（但し、ＢＰ：混合物１ｍ３当たりの高炉スラグ微粉末の配合量（ｋｇ）、ＮＰ：混合物１ｍ３当たりの普通ポルトランドセメントの配合量（ｋｇ）、ＦＡ：混合物１ｍ３当たりのフライアッシュの配合量（ｋｇ）、Ｗ：混合物１ｍ３当たりの水分量（ｋｇ））で規定される強度指数を１．８以上とすることにより、２８日養生後の圧縮強度が１５Ｎ／ｍｍ２以上となる固化体を得る。【選択図】なし
