초록
In this study, a new type of pile material with high economic efficiency and reliability for pile-supported embankment wasdeveloped using fly ash, blast furnace slag, and recycled aggregate, which are relatively low-cost industrial by-products. Aseries of strength experiments was conducted with the model piles fabricated using the developed new-type pile material toevaluate the design strength. As compressive strength of model pile decreases, the cost effectiveness also decreases. Based ontest results, the specimen with a composition of 50% fly ash and 30% recycled aggregate was suggested as the most economicalconcrete material to meet requirement strength of 25MPa for embankment piles. In addition, the applicability of thedeveloped material was evaluated by numerically analyzing its physical properties in the embankment pile test section. Fromthe numerical analysis results, we concluded the new-type cast-in-place pile material that utilizes industrial by-products canbe used as an embankment pile material.
