Exploring Geo-polymer Concrete with Recycled Steel Slag as Primary Aggregate

Structural Engineering

Abstract: Concrete production has been revolutionized by the advent of geopolymer concrete, which eliminates the need for traditional cement and offers a sustainable alternative for the construction industry. This paper investigates the feasibility and performance of incorporating recycled steel slag as the primary coarse aggregate in geopolymer concrete. The study aims to address the environmental challenges posed by conventional concrete production by utilizing industrial by-products. Experimental investigations involve analyzing the mechanical behavior, durability, and flexural properties of geopolymer concrete with scrap steel slag. Additionally, analytical investigations using ANSYS software are conducted to validate experimental findings. The results indicate improved compressive strength, resistance to acid and sulfate attacks, enhanced durability, and cost savings compared to conventional concrete. The paper concludes with suggestions for future research focusing on long-term properties, dynamic loading behavior, and alternative fine aggregate materials. Keywords: Geopolymer concrete, steel slag, sustainable construction, compressive strength, durability, finite element analysis, ANSYS.
