Engineering Properties of Conventional Concrete Containing Ferro Silica Slag as Course Aggregate

Abstract

Researchers now look for sustainable materials in the construction industry for insights into the lack of natural aggregates. The steel industry significantly contributes to environmental problems by accumulating various waste of slag. It can be recycled and used in concrete production. Ferro silica steel slag is derived from Electric Arc Furnace in coarse fractions (EAF slag). Ferro silica slag replaces natural coarse aggregates (CA) in conventional concrete (CC) in whole or part Ferro Silica Slag (FSS). FSS is a byproduct of the ferroalloy industry. Ferro Silica slag is a byproduct of the production of high carbon Ferro silica alloy. At 1700 degrees Celsius, this slag condenses into a liquid, and its main constituents are SiO2, Al2O3, and MgO. It also contains silica, ferrous/ferric oxides, and CaO. The present study proposes a novel method for creating constables from industrial waste. Slump monitoring percentages show that concrete workability is steadily declining. Workability, compressive strength, split tensile strength (STS), flexural strength, axial compression, and durability tests were performed on concrete containing coarse aggregate at FSS 0% to100%. The investigation discovered that adding FSS CA to concrete improved its hardened properties. At FSS 40% CA substitution, standard concrete properties are attained low values at all ages. The study results established by Ferro Silica Slag as a CA are suitable as a technical acceptability aggregate for concrete.
