Mechanistic insights into eco-efficient high-performance concrete with basalt powder: Microstructural refinement, durability modeling, and finite element validation

Year: 2026

Type: article

Abstract: This study investigates the eco-efficient potential of basalt powder (BP), a quarry by-product, as a partial replacement for natural sand in high-performance concrete (HPC). A multi-scale framework was employed, combining experimental testing, service-life prediction, and finite element analysis (FEA). At 20% replacement, BP enhanced compressive, tensile, and flexural strengths by ~12% compared to the control, while durability indicators confirmed nearly double the corrosion initiation time and reduced carbonation depth. Microstructural analyses (SEM, XRD, ITZ quantification) validated pore refinement and secondary C–S–H formation. Service-life modeling projected an extension from ~22 years (control) to ~55–60 years for the BP20 mix. Beyond technical improvements, incorporating BP conserves ~130 kg of natural sand per m3 and valorizes quarry waste, providing dual sustainability benefits. The findings highlight BP as a practical and eco-efficient solution for durable HPC, with direct implications for sustainable construction practices in line with international and Saudi building codes.
