In the domain of construction and sustainable building practices, the persistent issue of effectively utilizing recycled aggregates (RAs) has been a subject of considerable concern and research. One enduring challenge has been the removal of adhered mortar from RA, a crucial step in enhancing their suitability for reuse in concrete pavements addressing this challenge. The central objective is to investigate the efficacy of this innovative approach in improving the quality and characteristics of recycled aggregates for subsequent use in concrete production. The method begins with immersing RA in Acetic acid to remove existing adhered mortar, followed by mechanical treatment in the Los Angeles Apparatus to further eliminate any residual mortar. The concrete mixing process employs a two-stage technique and includes 20% fly ash to enhance the surface texture of the treated recycled aggregate (TRA). The study comprehensively assesses mechanical properties and durability, including compressive strength, flexural strength, rapid chloride permeability Test (RCPT), and scanning electron microscopy (SEM) analysis. The research findings indicate that the concrete samples exhibit satisfactory compressive and flexural strengths. However, a noticeable decreasing trend in these strengths as the replacement percentage of TRA increases. RCPT results suggest a moderate level of durability across all tested samples. SEM analysis reveals notable improvements in concrete properties, particularly in terms of enhanced voids and pore characteristics. Overall, this hybrid treatment approach could contribute to sustainable construction practices by optimizing the use of recycled materials while maintaining concrete strength and durability.
