Preliminary Assessment of the Economic Efficiency of Using Recycled Fine Aggregate in Self-compacting Concrete With High Fly Ash Content
Year: 2025
Type: article
Abstract: This paper presents a preliminary study on the economic efficiency of using recycled fine aggregate (RFA) from concrete waste, combined with a high fly ash content to produce self-compacting concrete (SCC) in Vietnam. Evaluation results indicate that using 100% RFA can reduce the material cost of SCC production to approximately 905,149 VND/m³, representing a decrease of 10.74% compared to SCC using natural sand and 31.64% compared to conventional concrete of equivalent grade (M400). The integration of RFA with high fly ash content emerges as a feasible solution, reducing construction costs while also contributing to environmental protection and natural resource conservation.
