In tandem with recent development of nanotechnology and reduction in cost of production, many nano-materials have been tried in concrete. In this study, the effect of nano silica (NS) on the carbonation resistance of concrete was investigated by producing a number of trial concrete mixes with varying water and NS contents for carbonation depth test. The results demonstrated that the addition of NS could significantly reduce the 28-day and 56-day carbonation depths of concrete, indicating that NS may be a promising supplementary cementitious material for producing high-performance concrete.
