Abstract
Copper slag obtained during smelting to extract copper metal from the ore. The review of the characteristics of copper slag encourages several applications such as for manufacture of cement, in aggregates, Landfill, glass, tiles etc. Many researchers have already found it is possible to use copper slag as a concrete aggregate. The workability and strength characteristics were assessed through a series of test on different mix proportions at 10% incremental copper slag by weight replacement of sand. M35 grade concrete was used and the tests were conducted for various proportions of copper slag replacement with sand of 0%,10%,20%,30%,40%,50%,60%,70%,80%,90%,100% in concrete. Then the concrete where cured for 7, 28, 60 and 90 days. Then they were tested for compressive strength, split tensile strength, and flexural strength. Finally the results were compared with the concrete made with the Portland Pozzolana cement (PPC) and fine aggregate (sand).
Highlights
The development of construction material have posed problem and challenges that initiated worldwide research programs and continued conventional and non-conventional application leading ultimate economy
40% replacement of copper slag the split tensile strength start decreasing but 50%, 60% and 80% of copper slag replacement gives more split tensile strength than the conventional concrete.From the result we can clinch that split tensile strength is increased at 40% replacement of fine aggregate by copper slag
From the result we can clinch that flexural strength is increased at 40% replacement of fine aggregate by copper slag
Summary
The development of construction material have posed problem and challenges that initiated worldwide research programs and continued conventional and non-conventional application leading ultimate economy. Researchers developed waste management strategies to apply for advantages for specific needs. A day’s incorporation of secondary material is being encouraged [1]. The government of India has targeted to reduce the industrial by product from the disposal. Harmful effects of concrete on environment can be reduced by producing good and durable concrete by using industrial by product [2]. Where copper slag is one the waste material which can be used as the replacement of find aggregate in construction which will reduce damage to the environment due to the waste resulting from the copper manufacturing process and helps in saving natural resources [3]
