METHOD FOR PRODUCING GROUND-IMPROVING MATERIAL AND GROUND-IMPROVING MATERIAL
To provide a method for producing a ground-improving material capable of sufficiently suppressing dust emission during ground improvement caused by evaporation of glycols and other liquid components.SOLUTION: This invention relates to a method for producing a ground-improving material that includes a cement-based hydraulic material and a dust inhibitor including at least one selected from the group consisting of glycols and glycol ethers, wherein the method includes: measuring whiteness L*0 in the L*a*b* color system chromaticity of the cement-based hydraulic material; preparing the ground-improving material by mixing the cement-based hydraulic material and the dust inhibitor; measuring whiteness L*1 in the L*a*b* color system chromaticity of the ground-improving material; and shipping the ground-improving material in which a value calculated by the following formula (1) is -0.111 or less. (L*1-L*0)/(100-L*0).....(1)SELECTED DRAWING: None
【課題】本発明は、グリコール類などの液分の蒸発が原因となる地盤改良時の発塵を十分に抑制できる地盤改良材を製造する地盤改良材の製造方法を提供する。【解決手段】本発明に係る地盤改良材の製造方法は、セメント系水硬性材料と、グリコール類及びグリコールエーテル類からなる群から選ばれる少なくとも１種を含む発塵抑制剤と、を含有する地盤改良材の製造方法であって、前記セメント系水硬性材料のＬ＊ａ＊ｂ＊表色系色度における白色度Ｌ＊０を測定することと、前記セメント系水硬性材料と前記発塵抑制剤とを混合して、前記地盤改良材を調製することと、前記地盤改良材のＬ＊ａ＊ｂ＊表色系色度における白色度Ｌ＊１を測定し、下記式（１）で算出される数値が－０．１１１以下となる前記地盤改良材を出荷することと、を有する。（Ｌ＊１－Ｌ＊０）／（１００－Ｌ＊０）・・・・・（１）【選択図】 なし
