An Experimental Study on Mechanical Properties of Concrete by Partial Replacement of Cement with Graphene Oxide

Abstract

Abstract: An essential building material, concrete is always changing for increased sustainability and performance. This study looks into the effects of replacing some of the cement in M60 grade concrete with graphene oxide. One amazing nanomaterial that is available in powder, sheets, flakes, and oxide form is graphene oxide. It has lately been used in the building industry and is robust, elastic, and lightweight. It has excellent qualities that are advantageous in the building industry. Adding graphene oxide to concrete composites improves binding strength to concrete structures, lowers permeability, and speeds up the pace of hydration. The concrete samples are tested for slump, split tensile strength, compressive strength, flexural strength, and durability after seven, twenty-eight, and fifty-six days. Graphene oxide concentrations in concrete compositions ranging from 0.5% to 2% by cement weight. The findings demonstrate that adding graphene oxide to concrete enhances its strength, with some mix compositions exceeding regular concrete. The mechanisms producing the strength increase are illuminated by the analysis of the experimental data, underscoring the potential of these additional components to enhance the durability as well as sustainability of concrete structures. These discoveries advance the field of construction material engineering by contributing to ongoing attempts to create high-performance and sustainable concrete compositions.
