copper slag can be used as a partial replacement for sand as fine aggregate in concrete up to 40% in pavement grade concrete with out any loss of cohesiveness and the compressive and flexural strength of such concretes is about 20% higher than that of conventional cement
So, the present study focuses to replace sand by welding slag (WS) and furnace slag (FS) in the production of concrete. Properties of aggregates and slag were studied in detail. M25 concrete was designed for various percentages of slag, and compressive strength of concrete was found out.
cement highest value of 30% replacement of steel slag with sand at 7 days and 28 days From the above Table 5 and Fig 1 represents the comparison of 7 and 28 days compressive strength of concrete with Replacement of GGBS with cement 0% and replacement of steel slag with River sand 30%, similarly 5%, 10%, 15%, 20%, and

slag as Partial replacement sand are economical. Key Words: Copper slag, Slump test, Compressive Strength, Split Tensile Strength 1.INTRODUCTION It is widely known India is a developing country due to rapid urbanization and industrialization it is necessary to construct so many infrastructure projects to meet the needs for that purpose
Cost analysis for M40 (steel slag and eco sand) were compared. 2. Materials Used The materials used are normal fine aggregate, normal coarse aggregate, steel slag, eco sand, and OPC of 53 grades after tested for their properties according tocodal provisions IS 2386:1963and the results are given in tables. Steel slag: The steel slag used here is an air cooled slag
