Description
Summary:The physical and chemical process at nano level manipulates the behavior of cement-based materials. Nanomaterials are highly effective in reinforcing and improving the properties of cement composites. Concrete is a heterogeneous composite material which is widely utilized in the construction industry. The microstructural performance, fresh concrete and hardened concrete properties vary due to complex nature of concrete ingredients. In order to improve the functional properties, convert conventional cement-based materials into stronger, more durable and smarter composites, nano materials are being used predominantly. Recent progress of nano materials on the influence of properties of cement composites, current developments and novel techniques are reviewed in this paper. This paper further summarizes the current understanding of the microstructure, mechanical and durability properties of cement composites by including various types of nanomaterials. Research available on nanomaterials has shown that it is possible to enhance the properties of conventional cement-based materials with the inclusion of nanomaterials. Some such nanomaterials include nano silica(ns), nano TiO2, CNT (Carbon Nano Tubes), nano graphene oxide(nGO) and nano ZnO. Further studies involving material characterization techniques to evaluate microstructural properties of cement nano composites at nanoscale are also discussed.
