Abstract
In this study, the mechanical properties of concrete composites containing Nano silica were investigated to produce more flexible and high-strength concrete. For this purpose, the different content of Nano-silica powder was added to concrete. The mechanical properties and the morphology of the sample were investigated. The mechanical properties such as flexural, tensile and compressive strength were significantly improved by incorporating the Nano-silica. Optimum composition containing 2.5 wt.% to 3.5 wt.% of nano silica was obtained, in which the tensile strength, compressive strength and flexural strength were expected increase for 0.25% to 1.28% respectively compared to the next concrete. Scanning Electron Microscope images showed that introducing the nano-silica into concrete improved the interfacial transition zone in between the cement particles. When SCC compared with Nominal Concrete, there is significant increase in workability and compressive strength. And also Normal SCC (without NS) is compared with Different small dosages of SCC with NS powder, there will be a significant increase in strength.
