Steel mill scale waste and granite powder waste in concrete production -An experimental study

Abstract

Fine aggregate is one of the large scale consuming materials in the construction industry. In general, river sand has been used as a fine aggregate for making concrete, mortar, etc. This river sand becoming one of the expensive materials due to its transportation from the source point and rapid consumption in the construction sector. Owing to the above circumstances, the concrete and construction industry needs a substitute for fine aggregate to be found. In this investigation, M20 grade concrete with the replacement of sand by steel mill scale waste and granite powder waste from 10% to 100% with the increments of 10%. This paper presents a detailed experimental study on compressive strength, bulk density, and water absorption of the M20 grade concrete containing steel mill scale and granite powder. The experimental outcomes indicate that the use of steel mill scale and granite powder in concrete showed improvement in the performance of concrete in strength and as well as in durability aspects.
