Abstract

The fast growth in industrialization has resulted in tons of by products or waste materials, which can be used as secondary cementitious materials such as fly ash, steel slag etc. The use of these byproducts not only helps to utilize these waste materials but also improves the properties of concrete in fresh and hydrated states. Steel slag and fly ash are the two materials used in concrete. Most concrete produced nowadays includes one or multiple materials. That is why their properties are usually compared to each other by mix designers, needed to optimize concrete mixtures. In the present work, a number of tests were carried out to make comparative studies of mechanical properties of concrete mixes prepared by using ultra tech brand Portland cement, fly ash in 20, 25, 30 and 35% proportions of replacement, steel slag in 20, 25, 30 and 35% of replacement. The fine aggregate used is natural sand belongs to zone II as per IS 383-1982. The coarse aggregate used is of 20 mm size. The properties were studied for 150 days for compressive and flexural strength.
