Strength properties of concrete using waste and industrial by products

Abstract

Growing industrialization leads to a large amount of trash being disposed of, which puts the environment at risk. A significant issue for these sectors is the disposal of the Industrial By-Products/Waste produced by the industry, which results in ground water contamination and an average annual production of 3 million tons of caustic waste. In both developed and developing nations, the rate of urbanization and industrialization rises with the production of industrial waste. The recycling or use of industrial waste by-products has grown in popularity as a disposal option due to growing environmental awareness of potential harmful impacts. This study finds a chance to assess the results of using substitutes for both fine and coarse materials with copper slag, iron slag and recycled concrete aggregate with varying amounts of mix. The mechanical parameters of both the recommended mix and normal concrete were measured and compared during the 28-day curing period. Results were intended to show the proper mix proportion that would produce the highest mechanical strength. The above-mentioned proportions were the subject of an experimental investigation. The study found that adding recycled concrete aggregate to conventional concrete mix strengthened it by 40% RCA, 40% iron, and 25% iron slag.
