The present invention relates to a solid fire reinforcing soft ground, and to a composition of solid fire optimum for the FJS process, which is a type of deep mixing process. The solidifying material is composed of a cement composition, an expanding material, a mixed material, and a hardening accelerator. Cement type uses fly ash cement and blast furnace slag cement as main raw materials, admixture is coal gasification combined cycle slag, expandable material is one or more materials selected from circulating fluidized bed fly ash, flue gas desulfurization gypsum and natural anhydrous gypsum, sodium sulfate, magnesium sulfate, The present invention relates to a solidified material composition for improvement in soft ground composed of at least one curing accelerator selected from aluminum sulfate, sodium carbonate and polycarboxylate. |
