Nanotechnology has nowadays a pronounced impact on several areas of science and industry. Among several advantages, nanomaterials have been reported to introduce improvements in terms of system reliability, extend functionality beyond traditional applications and decrease energy consumption in structures.Nanomaterials can enable better utilization of natural resources and reaching required materials properties with minimal usage. Nano-cement and nano-silica are among the recently used materials in this regard. The objective of this study is to explore the effect of incorporating nano-silica to concrete on enhancing mechanical properties and durability. This study concerns with the use of nano silica of size236 nm to improve the compressive strength of concrete. In this paper an experimental investigation has been carriedout by replacing the cement with Nano silica by 0%. 0.2%, .4% ,1.0%, and 1.1 % for M20 (1:1.4:2.74)grade of concrete with water cement ratio 0.42. The strength increase was observed with the increase in the percentage of Nano silica.
