Applicability & Durability Issues Of Nano-Sized Materials In Cement

Nano-sized Materials due to their smaller size exhibits many novel properties which may be absent in their conventional bulk material sizes. Cement is the most standard material among all of the materials used in cement concrete constructions and is the only binding medium. This Paper brings out the various beneficial aspects of Nano-sized Materials when they are applied in ordinary cement mortar. Nano-sized Materials viz. Nano Silica (nS), Carbon Nanotubes (CNT) and Nano Titanium Dioxides (n-TiO2) are non-virgin materials but when applied to a virgin cement medium like OPC not only enhances the mechanical properties but also increases the volume stability of cement-mortars to larger extent. Geo-polymers which are very low workability binders having no cement content, has their workability enhancement with Nano-sized Materials.
