Influence of Nano-filler content on the Freeze-Thaw cycle of the Nano-Concrete mixture

In this study, various concentrations (0%, 1%, 2%, and 4%) of nano-zinc oxide particles (ZnO) were introduced to conventional plain concrete, and the influence of such nanoparticles on the specimens' longevity during freeze and thaw circumstances was explored. The freeze-thaw resistivity and chloride (Cl-2) diffusion resistivity of mortar were evaluated with the aid of the Cl-2 diffusing co-efficient (CLDC) and comparative dynamic modulus of elasticity (CDM) of the mortar under the effect of nano-ZnO, respectively. The freeze-thaw resistance and Cl-2 diffusion resistance of nanoparticle-containing concrete were evaluated in comparison to that of ordinary samples. According to the findings, adding 2.0 percent nano-ZnO particles to regular concrete may lower the CDC by up to 24.5%, and the comparative dynamic modulus of elasticity of the traditional concrete mixture was prolonged by 16.13%. Further increment in nano-ZnO particles coulf end-up with a negative impact on the durability of the ordinary mortar.Copyright (C) 2022 Elsevier Ltd.
