초록

This study presents flowable fill material using collected CO2 byproduct, which prevents geotechnical sinking related to underground utilities in the vicinity of downtown areas. The physical and mechanical characteristics of calcium carbonate found using laboratory tests (the uniaxial compressive strength test, comparison of the shear base of dynamic behavior and restriction pressure, the freeze-thawing test) on 3, 7, 14, 28, and 56 days of the flowable fill were investigated and analyzed. The correlations of the unconfined strength, elastic modulus, flow, and w/c were suggested as evaluation indicators of the mechanical characteristics for the calcium carbonate flowable fill.
