crete or cement-stabilization soil. However, note that the soil is mostly acidic in Japan, and even when alkali contents are leached from slag, they will be absorbed in soil and neutralized as far as the slag use is adequate, and thus there will be no environmental prob-lem. However, when slag is used for civil engineering purposes in
