영문 초록

he tailings stocked at two tailing piles in Sangdong aea have raised collapse hazards and various environmental problems. A trial for effective utilization of tailings as fine aggregates for polymer concrete has been performed along with mineralogical and physical characterization of tailings. The tailings from the Sangdong mine, mainly composed of quartz, orthoclase, amphiboles and muscovite, are alkaline and tailings at the new tailing pile are generally finer in grain size than those at the old tailing pile. In case of using New Tailings as fine aggregates, cement mortar with equivalent amounts of tailings and sands shows the highest compressive strength. Cement mortars containing tailings show lower values of compressive strength, splitting tensile strength and flexural strength than those not-containing tailings. Mixture of polymers such as SBR and EVA in cement mortars raises strengths of cement mortars effectively, which shows potential possiblity to utilize the tailings in Sangdong area as fine aggregates for polymer concretes.
