MODIFICATION TREATMENT METHOD FOR DREDGE SOIL
To provide a modification treatment method for dredge soil which maintains an expression strength of modification treatment soil even when a volume mixing ratio of a steelmaking slag is reduced, and can increase a dredge soil treatment capacity to a modification treatment soil amount.SOLUTION: A modification treatment method for dredge soil is a modification treatment method for modifying dredge soil having a moisture content of 1.1-2.0 wL (wL: liquid limit), mixes a steelmaking slag and a modifier with the dredge soil to be formed into modification treatment soil, uses a paper sludge incineration ash-based modifier or cement as a modifier, reduces the volume mixing ratio of the steelmaking slag to the dredge soil, increases a treatment amount of the dredge soil to the amount of the modification treatment soil, and makes a strength of the modification treatment soil equal to or higher than a strength of a mixed material of the steelmaking slag and the dredge soil before the volume mixing ratio is decreased by mixing the paper sludge incineration ash-based modifier or the cement.SELECTED DRAWING: Figure 2
【課題】製鋼スラグの体積混合率を減らしても改質処理土の発現強度を維持し改質処理土量に対する浚渫土処理量を増やすことのできる浚渫土の改質処理方法を提供する。【解決手段】この浚渫土の改質処理方法は、含水比が1.1〜2.0wL（wL：液性限界）である浚渫土を改質する改質処理方法であって、浚渫土に製鋼スラグと改質材とを混合して改質処理土とし、改質材としてペーパースラッジ焼却灰系改質材またはセメントを用い、製鋼スラグの浚渫土に対する体積混合率を減らし、改質処理土の量に対する浚渫土の処理量を増加させ、ペーパースラッジ焼却灰系改質材またはセメントの混合により、改質処理土の強度を、体積混合率を減らす前の製鋼スラグと浚渫土とによる混合材料の強度と同等またはそれ以上とする。【選択図】図２
