proving quality of concretes containing pozzolanicement with nano-silica

In order to be able to make nano-technology appear in the concrete industry, researchers were faced with special concrete that is different from any conventional concrete in every dimensions. This paper introduced nanotechnology, statedreasons of its usage in concrete technology with design and construction of Pozzolanicconcrete samples containing nano-silica and compares their mechanical properties such as compressive strength and tensile strength of control sample at different ages. Moreover it has reviewed the effects and properties of this material in improvingpozzolanic weaknesses which can be seen in projects using too much concrete.
