An experimental study on micro-structure and hardened properties of ultra-high strength self-compacting concrete by incorporating Graphene Oxide

Abstract

The modern material in the rapidly expanding building sector is ultra high strength self-compacting concrete (UHSSC). There are several ways to make UHSSC, but one of the best ways is by employing graphene oxide to improve the microstructure of cement (GO). GO is a cutting-edge nanomaterial that excelled in a number of disciplines. This study examines the microstructure and toughened characteristics of UHSSC with GO incorporation. Improved GO dispersion in the concrete is achieved by using silica fume (10% cement weight), while better pore structure and resistance to chloride penetration are achieved by using GGBS (30% cement weight). To achieve UHSSC, GO is added to cement at concentrations of 0.25, 0.5, 0.75, 1.0, and 1.25% by weight of cement. EDS (Energy dispersive x-ray spectroscopy) technique is used to determine the crystalline properties of GO nanomaterial and SEM (Scanning electron microscope) is used to determine the microstructure of the GO incorporated UHSSC.
