Abstract: Marine concrete structures are subjected to very severe exposure conditions and their durability is directly related to the quality of concrete used in the construction due to the salinity present in water .The present study intends to evaluate the strength and bonding property of copper slag in sea water concrete (SWC) and tap water concrete (TPC). In total the mixes were cast with 25% using copper slag as a substitution for fine aggregate at constant w/c 0.4 for M40 mix grade. The various tests conducted on different concrete mixes included fresh properties, compressive strength, split tensile strength, young’s modulus, flexural and bond strength. Results showed that fresh properties enhanced with increment in copper slag substitution. The experimental trails were carried out for higher strength and durability. The projected mix design method was found to be agreeable for producing concrete with fine aggregates having different properties. The pH of sea water used fluctuates between 6.4 to 8.10. The specimens were casted for various sea water having different pH the strength was compared with the control specimen.
