Description
Summary:High-volume fly Ash (HVFA) concrete has gained significant attention recently due to its potential for reducing environmental impact and improving long-term durability. This project investigates HVFA’s influence on concrete rheology, aiming to explore its applicability in sustainable construction. HVFA concrete mixes M1 (30% fly ash), M2 (40% fly ash), and M3 (50% fly ash) were prepared, varying fly ash percentages as a partial cement replacement. Fresh concrete tests, including slump cone and flow table tests, assessed workability and flow characteristics. Hardened samples underwent compressive and split tensile strength tests to evaluate mechanical properties. Results provided insights into HVFA concrete rheology, focusing on workability, flowability, and mechanical performance. Additionally, the study explores potential environmental benefits and challenges linked to HVFA concrete. These findings aid in advancing sustainable concrete technologies, offering crucial insights for engineers, architects, and policymakers seeking innovative, eco-friendly construction materials and practices while addressing environmental challenges related to HVFA concrete.
