STUDY ON SOLIDIFICATION PERFORMANCE USING ELECTRIC ARC FURNACE REDUCED SLAG FOR PILE-SHAPED GROUND REINFORCEMENT METHOD

Abstract

We conducted a stirring and mixing test of a cement-based pile-type ground reinforcement method with addition of electric furnace reduction slag on soft ground, which is intended for humus soil. As a result, in the humus soil, (1) the electric furnace reduction slag (S) is 200 kg/m3, the blade cutting frequency is 800 times/m, and (3) the solidification material slurry injection rate is 46.5%. It was found to be 340 kN/m2 or more.
