Abstract
Fly ash, a byproduct of coal combustion in thermal power plants, has emerged as a sustainable and effective supplementary cementitious material in concrete technology. Its incorporation in high-performance concrete (HPC) enhances mechanical properties, durability, and workability while reducing environmental impact. This paper investigates the effects of various percentages of Class F fly ash on the fresh and hardened properties of HPC. The study includes a comprehensive literature review, experimental methodology with controlled mix designs, and statistical analysis of mechanical strengths and durability parameters. Results demonstrate significant improvement in compressive strength, reduced permeability, and enhanced durability characteristics with optimal fly ash substitution. The findings affirm fly ash as an eco-friendly additive to develop HPC suitable for modern infrastructure demands.
