EXCHANGING CEMENT AND RIVER SAND PARTLY BY USING “GROUND GRANULATED BLAST FURNACE SLAG (GGBS) ” & “COPPER SLAG (CS)”

The construction industry consumes a huge amount of concrete due to fast urbanization and an increase in the construction field is depleting the resources of natural sand and manufactured sand at a high rate of concern hence leading to various problems in the environment. Besides that, cementitious material in concrete releases a large amount of CO2 into atmosphere. Similarly cost of concrete is attributed to the cost of its ingredients. The concept of using eco-friendly materials in concrete enhances scope for green concrete which utilizes many kinds of industrial by-products thus resulting in the use of substitute materials which are economical in concrete production. This has attracted the attention of investigators to look out for new replacements for fine aggregate and cement. The copper slag, which is an industrial by-product produced while smelting and refining copper may be a partial alternative for fine aggregate and GGBS, a byproduct of steel manufacturing industry can effectively replace cement with better durable concrete mix. In the present study river sand will be partially substituted by Copper slag 35 % constant and cement will be partially replaced by GGBS 5%, 10% and 20% and The strength parameters such as compressive strength, tensile strength will be confirmed for both 7 days, 14 days and 28 days of curing period. Based on the test appropriate results will be derived.
