SOLIDIFICATION AID, SOLIDIFICATION MATERIAL AND SOLIDIFICATION METHOD
To provide a solidification aid capable of enhancing a strength of an organic matter containing soil to be treated, a solidification material containing the same and a method for treating soil.SOLUTION: There is provided a solidification aid which contains a blast furnace slag fine powder and ferrous sulfate, has a mass ratio of ferrous sulfate to a blast furnace slag fine powder of 0.01 to 0.49, is in a hydrous state and is used for solidification treatment of an organic matter containing soil having a content of a humic substance of 5 mass% or more. In addition, there is provided a solidification material which contains the solidification aid and a cement based solidification material containing a blast furnace slag, wherein the ratio of the solidification aid to 100 pts.mass of the cement based solidification material is 20 to 70 pts.mass. Further, there is provided a method for treating a soil which comprises a step of mixing the solidification material and a soil to be treated.SELECTED DRAWING: None
【課題】処理対象となる有機質含有土の強度を高めることができる固化助材、及びこれを含む固化処理材、並びに土の処理方法を提供すること。【解決手段】本発明の固化助材は、高炉スラグ微粉末と硫酸第一鉄とを含み、高炉スラグ微粉末に対する硫酸第一鉄の質量比が０．０１〜０．４９であり、含水状態であり、且つ腐植物質の含有量が５質量％以上である有機質含有土の固化処理に用いられる。また本発明の固化処理材は、前記固化助材と、高炉スラグを含むセメント系固化材とを含み、前記セメント系固化材１００質量部に対する前記固化助材の割合が２０〜７０質量部である。更に、土の処理方法は、前記固化処理材と、処理対象の土とを混合する工程を有する。【選択図】なし
