A Study on the Stabilization Plan of the Fine Aggregate in the Southeastern Area Due to the Reduction of Sea Sand Collection

바다모래 채취량 감소로 인한 동남권 잔골재 수급안정화 방안에 관한 연구

It is expected that the proportion of crushed aggregate will increase in order to fill the decreasing supply of sea sand in the southeast area. However, it is necessary to supply the least amount of sea sand to diversify the aggregate source, in order to minimize the mixing ratio of sea sand and crushed sand to minimize the structural stability of the concrete.
