GREEN CONCRETE: ENHANCING STRENGTH AND WORKABILITY FOR SUSTAINABLE CONSTRUCTION

Abstract

This study looks into the viability of employing fly ash and limestone powder as partial replacements for cement in green concrete, which could replace regular concrete. The goal is to preserve mechanical efficiency and reliability while mitigating ecological impact, especially carbon dioxide emissions. Compressive capacity, flexibility, and long-term sustainability indices were assessed experimentally for different mix amounts. According to the findings, green concrete mixtures that have been optimized can both meet structural needs and provide substantial environmental advantages. The construction sector is one of the major consumers of natural resources and contributors to environmental deterioration, owing to the widespread use of cement in concrete manufacturing. This environmentally friendly concrete substitute provides considerable sustainability advantages by adding eco-friendly elements such as fly ash and limestone powder. This study looks into the feasibility and performance of substituting conventional concrete with green concrete that includes fly ash and limestone powder as partial cement replacements. The paper analyzes the mechanical properties, environmental benefits, and practical challenges of using these materials. Experimental results indicate that green concrete can achieve comparable strength and durability while significantly reducing carbon emissions and overall costs.
