Analysis of the Use of Fly Ash Variations as a Partial Cement Substitute for Roller Compacted Concrete (RCC) Mixtures

Year: 2025

Type: conference-paper

Abstract: Roller compacted concrete (RCC) is a relatively stiff concrete mixture generally designed with a zero-slump value and compacted with a vibratory roller. It is commonly used in pavement construction. To reduce the utilization of cement, this study employs fly ash at variations of 0%, 40%, and 50% as cement replacements to study fresh concrete’s workability and the hardened concrete’s mechanical properties. The workability of fresh concrete coming from the vebe test result shows that all the mixtures, according to Brownsville TX, meet the workability criteria as RCC. Moreover, it is concluded that using fly ash as a partial replacement for cement has a positive impact on the compressive strength and splitting tensile strength of concrete.
