고로슬래그 미분말을 활용한 경량혼합토의 특성에 관한 연구

초록

This study developed rapid backfill after open-cut construction of Near-surface transit. For this purpose, soil generated on site was collected and analysed physical properties of that. And then, light mixed soil with 300 and 500 KPa were manufactured using ordinary portland cement(OPC) and slag cement. Then, the unconfined compressive strength and CO₂ emission were measured for the light mixed soil specimens. It was observed from the results that light mixed soil using slag cement satisfy the required unconfined compressive strength and reduce CO₂ emission compared light mixed soil using OPC.
