초록

The purpose of this study is to research the basic property of mortar as the grading distribution of copper slag used as fine aggregate and the results are as follows. The compressive strength of mortar as the size of largest diameter of copper slag granule is the highest when the largest size is in 2.5-5mm, and flow of mortar is in proportion to the size. As the largest size of copper slag particle is under 2.5mm(Type 1) the compressive strength and flow is higher as the big granules is more included than small ones. As the largest size of copper slag granule is under 5mm(Type 2) the compressive strength and flow is similar to situation of Type 1, except compressive strength is higher as the percent of the size of granule in $2.5\~5mm$ is under 35$\%$. F.M.(Fine Modulus), compressive strength and flow is relative each other except the batch with 2.5$\∼$5mm granule size of copper slag.
