A survey on the application of oxide nanoparticles for improving concrete processing

The evolution of nanotechnology provides materials with advance properties. It's a fast growing area of research to introduce the oxide nanoparticles into the cement pastes to improve their performance. The purpose of this paper is to review the effects of oxide nanoparticles (such as <TEX>SiO₂</TEX>, <TEX>TiO₂</TEX>, <TEX>Fe₂O₃</TEX>, <TEX>ZnO₂</TEX>, <TEX>Cr₂O₃</TEX> and <TEX>Al₂O₃</TEX>) on both of hardened concrete properties (i.e., compressive strength, split tensile strength and flexural strength, water permeability, Abrasion resistance and pore structure of concrete) and fresh concrete properties (i.e., workability and setting time). Graphical representations of all these parameters were presented to facilitate the comparison of the effect of oxide nanoparticles on concrete processing. The paper also introduces some discussion about future work in this direction by identifying some open research area.
