Investigation on strength and durability characteristics of high performance concrete containing hybrid nanoparticles

Abstract

This newlineresearch investigates the performance, durability, and newlinesustainability of concrete mixes incorporating nanosilica (NS), veli karuvelam newlinecharcoal (VKC), and nano zeolite (NZ) as partial replacements for ordinary newlinePortland cement (OPC). The study aims to explore how these supplementary newlinecementitious materials (SCMs) influence the mechanical properties, durability newlinecharacteristics, and environmental benefits of concrete. This investigation is newlinemotivated by the pressing need for sustainable construction materials that newlinebalance performance with reduced environmental impact. The study evaluates newlinekey parameters such as workability, compressive strength, split tensile newlinestrength, flexural strength, water absorption, permeability, acid resistance, newlinesorptivity, and ultrasonic pulse velocity (UPV) for M50 and M70 grade newlineconcretes at various curing ages (7, 28, and 90 days). newline
