Abstract

Now a days, the application of waste material usage in building materials has increased effectively. Copper slag is a by product created during the copper smelting and refining process. This material represents a popular alternative to sand. Natural sand is used from river bed for all construction stage. Decreasing natural resources create the environmental issues and hence restriction on sand resulted in scarcity and increased in its cost. After long investigation industries and investigator all over the world to explore the possible utilization of copper slag. This paper mainly shows the corrosion in concrete by using copper slag and preventive measures from corrosion. In this project M30 grade of concrete is used. Two different types of corrosion inhibitors were used calcium nitrate and concare . The influence of copper slag on concrete was investigated with respect to the properties of concrete in the fresh state workability and hardened state mechanical properties and durability . Strength properties of concrete increased 40 replacement of fine aggregate by using copper slag. However further addition of copper slag caused reduction in strength. From chemical composition of copper slag Fe2O3 present in more than 55 . So that here concrete itself getting corrode. Here corrosion inhibitors at the amount of 1 , 2 and 3 by the weight of cement in concrete having copper slag as a fine aggregate is used. Effect of this inhibitor was derived from gravimetric method. P. Nithya | K.
