Effective role of graphene oxide nanostructured materials in enhancing the physico-mechanical characteristics of concrete structures

Abstract

Nanostructured graphene oxide (GO) materials have been studied world-wide for various technological applications now-a-days. Due to its good dispersability in water, this can exhibit high aspect ratio.  In this research work, a detailed experimental study has been carried out on concrete with addition of GO in appropriate levels (0, 0.03 and 0.06 wt%). The addition of GO after sonication in water was carried-out in the concrete at the time of mixing the cementitious material along-with other conventional additives.  The prepared concrete cubes, cylinders and prisms with / without GO were studied for the compressive strength, flexural strength, elastic modulus and ductility index.  The hydration process in concrete were enhanced effectively with the presence of GO and enhanced the concrete properties to a greater level.
