In this paper, our concern is to produce light-weight concrete with using different ingredients in the concrete mix. Specimens were satisfied the density and strength regulators of structural lightweight concretes. The final aim is to increase ultimate strength and effects of added Nano-silica and steel fiber on the mechanical behavior. Nano-silica increases tensile compression and flexural strength with improving the concrete structure (Quercia et al. 2010). In the other hand, using steel fibers reduces the crack width and parallelize their orientation by bridging between microcracks (Qing et al. 2007).
