Copper slag and lime are used at varying percentages ranging from 25% to 75%. We are expecting that the strength properties of soils improved with an increase in percentages of copper slag and lime waste. The maximum strength is obtained at 50% copper slag and 50% lime at 15% water content for intermediate compressible soil.

FLEXURAL BEHAVIOUR OF SELF COMPACTING CONCRETE BY USING COPPER SLAG Dinesh S Assistant Professor Theni Kammavar Sangam College of Engineering and Technology Theni – 625 534, Tamilnadu, India Abstract— In recent years, self-compacting concrete (SCC) has gained wide use for placement in congested reinforced
of bleeding increased by using copper slag fine aggregate de-pending on the water to cement ratio, the volume fraction of slag and air content. They recommended using less than 40% copper slag as partial replacement of aggregate to control the amount of bleeding to less than 5 l/m. 2. Studies by Alnuaimi indicated that replac e-
One such alternative is copper slag (CS) obtained as byproduct during the matte smelting process of copper metal. The present investigation is aimed to assess the durability of self compacting concrete (SCC) incorporating copper slag (CS) as fine aggregates and .
