Durability Investigation on Nano Silica and Nano Cement Based Concrete

Nanotechnology is new addition to 21^st century while compared to other technologies; nanotechnology is different from normal technology and well-structured. Until today, concrete helps for better performance of structural members. Nanotechnology is used to make small material. Concrete can be nano-engineered e.g., (nano particles, nano admixtures and nanotubes) to control material behavior and grafting of molecules in to cement and additives to provide the surface functionality adjusted and it has interaction between molecules. In this project the properties of Nano materials were studied and their effect of strength and durability where studied. Nano silica and Nano cement based concrete where found to be more durable and their compressive strength where equal to conventional concrete.
