A critical assessment on the effect of nano-titanium dioxide on the properties of concrete
Abstract
Recent advances in nanotechnology in various fields demonstrate tremendous promise for resolving a wide variety of problems. Nanotechnology has been shown to improve the efficiency of conventional building materials such as concrete. Numerous types of nanoparticles, such as nano-titanium dioxide, are being used to significantly improve the efficiency, longevity, and sustainability of concrete. This paper summarises prior research on the effect of nano-titanium dioxide on a variety of properties, including heat of hydration, workability, setting time, chemical shrinkage, mechanical strength, abrasion resistance, fire resistance, and freeze/thaw resistance. Water absorption, chloride penetration, and permeability are all low in conventional plain or blended cement systems. Additionally, the matrix containing nano-titanium dioxide is compared in this study to a matrix containing other nanoparticles. Civil engineers can use this paper as a quick reference.
