Abstract
Abstract
Concrete, the cornerstone of modern infrastructure, faces increasing environmental impact of cement production calls for sustainable alternatives in construction materials. Primarily due to the high carbon footprint associated with Portland cement production. This review synthesizes existing research and the findings from an experimental study investigating the partial replacement of Ordinary Portland Cement (OPC) with fly ash in high-strength concrete (HSC) of grade M60. The study specifically examines a 50% replacement level of cement with Class C fly ash, evaluating its influence on compressive strength development over 7, 14, and 28 days. Furthermore, this review delves into the broader implications of fly ash utilization in concrete, encompassing sustainability benefits, enhanced durability, cost-effectiveness, and long-term performance. The experimental results indicate a gradual strength gain in fly ash-amended concrete, achieving a 28-day compressive strength of 45 MPa. While this is below the target strength of 70 MPa, the trend suggests potential for long-term strength development, aligning with findings from reviewed literature. This paper underscores the necessity for optimized mix designs and extended curing regimes to fully leverage the benefits of fly ash in high-strength applications, contributing to a more sustainable and resilient construction industry.
