Strength and durability studies on concrete containing nano-fine cement

Abstract

The research paper presents the experimental results of mechanical strengths as well as the durability of nano-fine cement incorporated concrete. The present study is dealing with the pulverising the ordinary Portland cement to the nanofine scale (~250nm) using the high energy milling process, which is a top-down approach. The fine grind cement is explicated by particle size distribution analysis and by analytical techniques. Pulverising able to produce 50% of the cement particles < 250nm after 90 minutes milling. In the present research 0%, 10%, 20%, 30%, 40% and 50% of nanofine cement as partial replacement of cement in concrete mixture with 0.45 water-cement ratios was used.Mechanical strength properties of concrete have been investigated, and durability study includes corrosion resistance as well as resistance to chemical attack. Based on the experimental data, concluded that the 30% nanofine cement as a partial replacement, improves mechanical strengths and corrosion resistance of concrete.
