Economical Concrete Cube Prepared Using Different Types of Nano-Material for Sustainable Construction

Abstract

In this research work concrete cube has been prepared by doing partial replacement for cement using nano materials like Multi-Walled Carbon Nano Tubes (MWCNTs), titanium dioxide (TiO2), and copper oxide (CuO) at different percentages like 0.1, 0.25, and 0.5%. Basic test has been done for materials and fresh concrete, followed by compressive strength test for concrete cubes. MWCNT gives more result compare to TiO2 and CuO. Just to reduce cement usage, fly ash has been used by keeping the compressive strength and the amount of nano materials as constant up to 35% of MWCNTs, TiO2, and CuO, with fly ash replaced for cement to obtain the normal strength. Cost analysis has been done to find out the economic efficiency of nano material concrete cube due to which TiO2 with fly ash cost 14.45Rs to prepare single cube, as MWCNTs and CuO with fly ash cost 726.4 and 17.64Rs to prepare single concrete cube. Almost TiO2 cube preparation took 10% reduction for the preparation of concrete cube compare to normal concrete cube has taken 15.96Rs. So we concluded that TiO2 with fly ash nano material concrete is the economical efficient concrete compared to MWCNTs and CuO with fly ash.
