DUST EMISSION DEPRESSANT, SOIL IMPROVEMENT MATERIAL AND MANUFACTURING METHOD OF SOIL IMPROVEMENT MATERIAL
To provide a dust emission depressant capable of preventing a deterioration of uniaxial compressive strength in improved soil, as well as preventing an elution of hexavalent chromium or fluorine, and to provide a soil improvement material and a manufacturing method of a soil improvement material.SOLUTION: A dust emission depressant is used for a soil improvement material to be mixed with object soil. The dust emission depressant includes an alcohol compound, a reductant and water. A content of the alcohol compound is, based on 100 pts.mass of water, 100 pts.mass or more, and a content of the reductant is, based on 100 pts.mass of water in anhydride conversion, 70 pts.mass or less.SELECTED DRAWING: None
【課題】改良土の一軸圧縮強さの低下を抑え、六価クロム、ふっ素の溶出も抑えることが可能な発塵抑制剤、地盤改良材、及び地盤改良材の製造方法を提供する。【解決手段】発塵抑制剤は、対象土と混合する地盤改良材に用いられる発塵抑制剤であって、アルコール化合物と、還元剤と、水と、を含み、アルコール化合物の含有量が、水１００質量部に対し、１００質量部以上であり、還元剤の含有量が、無水物換算で水１００質量部に対し、７０質量部以下である。【選択図】なし
