What is High-Strength Concrete with Fine Fly Ash about?

This study investigates the properties of high-strength concrete using Class F fine fly ash (FFA) as a partial replacement for cement. The optimal replacement level was found to be 10%, resulting in 28-day compressive strengths of 94 MPa and 111 MPa for mixtures with 400 kg/m3 and 500 kg/m3 of total cementitious materials, respectively. The research also examined workability, drying shrinkage, water absorption, and mechanical properties, demonstrating that FFA can enhance concrete performance while being en
