 Abstract
In 2019, about 134 million m3 of aggregate was produced in an estimated 880 quarries and pits in 17 metropolitan governments. Leading producing metropolitan cities were Gyeonggi-do, Gyeongsangnam-do, Chungcheongbuk-do, Gangwon-do, Gyeongsangbuk- do, Chungcheongnam-do, in order decreasing volume, which together accounted for about 71% of total product. Of the total domestic aggregates produced in 2019, about 31 % was sand and about 69% was gravel. It estimated that of the 134 million m3 of aggregates in Korea in 2019, about 50.3% was produced by screening crushed aggregate by 41.4% by forest aggregate, 3.3% by land aggregate, 1.7% by sea aggregate and 1.7% by washing each other, and 0.7% by river aggregate. This indicates that screening crushed aggregate and forest aggregate are the main producers of domestic aggregates. The most crushed and forest aggregate was extracted at the Gyeonggi-do and Gyeongsangnam-do, respectively. Land aggregate was mainly extracted at Gyeongsangbuk-do and Gangwon-do. Therefore, in the future supply and demand of aggregate resources, it is judged that there should be a primary policy direction for screening crushed and forest aggregate.
