During 2008 about 3 billion tons of concrete were produced all over the world, making it the most important industrial product produced in the history of mankind. Therefore, any technological improvement in this product will affect any part of the globe money wise and environment wise. Concrete is mainly a mix of three different components that work together to produce such extraordinary material. Hence, depending of the size of the sand grains and the size of the rocks mix, the final concrete obtain their mechanical characteristics. The scope of this research is to create atomic devotion in the final mix, since it is presume that the concrete aggregates only have mechanical forces and lacks of atomic bonds between its final components. Hence, it is report that concrete aggregates only have about 10% of compression resistance and tension resistance. In order to achieve atomic adherence between components our research explores the use of nanofibers made out of polyethylene. Our work studies the phenomena and the interactions of the nanofibers with the growth of crystals in the concrete and its atomic interface at the time of formation of the substrate.
