Abstract

Concrete is the most basic and the most essential building material which is used in any construction industry. It is plastic and mouldable when it is in crisp state. How ever gets solid and strong when solidified. Concrete is a building matter collectively composed of water, FA and CA embedded in a harden matrix of materials, which fills up the voids among aggregates and adheres them strongly. Concrete is good in compression but weak in tension, therefore the reinforcements are provided so that the required strength can be achieved in the tension zone. The usage of wastes such as copper slag getting prioritized as additives, by using these wastes in concrete, the strength can be effectively achieved & the problem of disposal of these wastes can be greatly reduced. In the present thesis work, the properties of concrete are thoroughly studied with addition of industrial wastes obtained from copper industries & easily available cheap mineral known as quartz sand. Copper slag which is used in the sand blasting whereas quartz sand is used in glass manufacturing using these material as partial replacement of fine aggregate in M25 grade concrete. The IS codes used in this experimental work are IS 2720-part 3, IS4031 –part 1, IS383 1970, IS 2386 part III-1963. Various proportions of copper slag replacement of fine aggregate & quartz sand replacement were adopted i,e 0%, 20%, 30%, 40%,50% by volume of fine aggregate. The parameters such as strength aspects are examining in this work. The best proportions will be chosen and are compared based on based on the various test results such specific gravity tests compressive strength split tensile strength and flexural strength test. In this project the workability seems to increase with the addition of copper slag and quartz sand. Strength aspects such as compressive, Tensile and flexural strength tests are conducted. The compressive strength for concrete containing 40% of copper slag as partial replacement of fine aggregate for 28 days of curing is 39.40 respectively. Split tensile for 40% copper slag replacement fine aggregate for 28 days of curing is 4.61 respectively. Flexural strength for 40 % copper slag replacement of fine aggregate for 28 days of curing is 4.96, all units are in N/mm2. The compressive strength for concrete containing 40% of quartz sand as partial replacement of fine aggregate for 28 days of curing is 37.47. Split tensile for 40% quartz sand replacement of fine aggregate for 28 days of curing is 4.47. Flexural strength for 40 % quartz sand replacement for 28 days of curing is 4.88, all units are in N/mm2. From the experimental study and comparing of results it is found that the strength such as compressive, split tensile and flexural obtain from optimum replacement percentage of copper slag which is 40% is greater than the strength obtained from optimum replacement percentage of quartz sand which is 40%.
