Due to increasein rapid advancement of infrastructure system the requirement of sustainable materials in construction is essential. It is very difficult to overstate the role of material (SAND) today as it plays a prominent role in concrete production. In recent years, due to excessive and gravel mining the dredging of river beds affects the structures spotted nearby. And also created a huge problem to human and environment. And also in order to protect the natural availability of resources like sand and gravel, My research study was intensively focused on replacement of fine aggregate with copper slag (In 0%,10%,20%,30%,40%and50%) proportions. Copper slag is an industrial waste from Copper industry .By using copper slag in construction work we can reduce the open land dumping there by protection of imprudent place as well as natural resources .Along with copper slag 0.25% carbon fibers were added as admixture constantly for all 5 mixes as they will increase crack healing capacity ,high durability and higher tensile strength . Main aim of present work is to show the effective usage of copper slag and to study the durability properties, Acid attack test, RCPT, Abrasion resistance test were conducted for all mixes with different copper slag percentages.% Loss in weight and compressive strength was 0.177and 2.03 and Amount of charge passed was 345.6mA having abrasion depth of 0.0093mm at 30% replacement of fine aggregate with copper slag while the Nominal mix having % Loss in weight and compressive strength was 2.52 and 11.205 and Amount of charge passed was 1043.1mA and abrasion depth of 1.65mm.
