To provide a cement-based solidification material that has solidification soil strength remarkably increased by solving the problem in which clinker is troublesome to make it and solidification soil strength is not enough.SOLUTION: A cement-based solidification material contains Portland cement of 30 to 85 mass%, blast furnace slag powder of 10 to 50 mass%, and gypsum of 5 to 20 mass%, in which a hydration heat generation rate measured by a conduction calorie meter has a third peak higher than a second peak, and the second peak is expressed between 5 and 20 hours after water-kneading and the third peak is expressed between 20 and 50 hours after water-kneading.SELECTED DRAWING: Figure 2
【課題】クリンカの製造が面倒であり、固化処理土の強度が十分ではないと云う問題を解決し、固化処理土の強度を格段に高めたセメント系固化材を提供する。【解決手段】ポルトランドセメント３０〜８５質量％、高炉スラグ粉末１０〜５０質量％、および石膏５〜２０質量％を含み、コンダクションカロリーメータによって測定した水和発熱速度について、その第三ピークが第二ピークより大きく、かつ第二ピークの発現が水混練後から５〜２０時間の間であって第三ピークの発現が水混練後から２０〜５０時間の間であることを特徴とするセメント系固化材。【選択図】図２
