Assessment of the Durability Dynamics of High-Performance Concrete Blended with a Fibrous Rice Husk Ash

The present study examines the durability properties of Class 1 (50–75 MPa) high-performance concrete (HPC) blended with rice husk ash (RHA) as a partial replacement CEM II B-L, 42.5 N. Six HPC mixes were prepared RHA and used 5%, 10%, 15%, 20%, 25%, 30% alone are compared control mix having only II. binders (CEM RHA) investigated for particle size distribution (PSD), specific surface area (SSA), oxide compositions, mineralogical phases, morphology, functional groups using advanced techniques laser PSD, Brunauer–Emmett–Teller (BET), X-ray fluorescence (XRF), diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared/attenuated total reflection (FTIR/ATR), respectively, to understand their import on HPC. Durability properties, including water absorption, sorptivity, chemical attack samples, realise effect matrix. findings revealed that RHA-based HPCs exhibited an acceptable range values consistent relevant standards. established self-produced would be beneficial cement in As is cost-effective agro-waste, scalable product resource sustainable technology.
