Abstract: Nanotechnology is both a science and a technology that has been around for a long time. Instead, it is an extension of the sciences and technologies that have been developing for many years. It is the logical advancement of the work that has been done to investigate the nature of our world at an ever-smaller scale. Nanotechnology uses very small particles of material either by themselves or by their manipulation to create new large scale materials. This research aimed to investigate the effects of using Nano-silica and internal injection by epoxy on the flexural behavior of reinforced concrete beams. The results show that the combined use of Nano-silica with silica fume can improve the mechanical properties of concrete. In this research, the tests were applied on fourteen reinforced concrete beams specimens of dimensions (150×100×1800 mm), and divided into four main......
