Research was conducted to investigate the durabilities studies of concrete which containing copper slag replaced
with sand (fine aggregate) and results have been presented in this paper. Two different types of Concrete Grade (M35 &
M40) were used with different proportions of copper slag replacement (0 and 40%) in the concrete. Durability studies such
as Rapid Chlorine Penetration Test (RCPT), Accelerated Corrosion Test, Sorptivity Test, Water absorption test, Acid attack
and Sodium Chlorine attack test for both concrete mixes. Test results shows that the Durability properties of concrete has
improved in sorptivity and water absorption but it should not able to resist in RCPT and Accelerated corrosion test and
result of acid attack and Sodium chlorine attack concrete mix shows weaken strength and considerable weight loss which
having copper slag as a partial replacement of sand (upto 40%) in concrete.When copper slag replaced with sand 40% it
shows considerable high compressive strength than Conventional Concrete mix (CC).
