Copper slag as fine aggregate for high performance concrete

copper slag as fine aggregate on the properties of normal concrete. Akihiko and Takashi [3] investigated the use of slag from copper smelting as a fine aggregate in concrete. From mortar strength tests with a cement/slag/water ratio of 1/2/0.55, the ball milled slag gave a higher strength. The effects of
