Abstract
Integration of nano-materials as supplementary cementitious materials has proven to improve the mechanical and durability properties of concrete. This paper aims to provide a brief review on the utilization of nano-SiO2, nano-Al2O3, graphene oxide, carbon nanotubes, nano-TiO2, nano-Fe2O3, nano-clay/metakaolin, and nano-CaCO3 on the workability and compressive strength of cement concrete. It has been identified that the utilization of nano materials as a partial substitute for binder or as a filler material in cement concrete modifies the rheology and the microstructure at the nano scale, significantly improving the mechanical and durability characteristics of cementitious composites. This review highlights the positive impacts and the limitations in using these nano materials. It is expected that this brief review will provide a better insight for its practical application in the construction industry.
