Cement-Based Graphene Oxide Composites: A Review on Their Mechanical and Microstructure Properties

Abstract

Concrete is a material made from cement that is widely used because it has a high compressive strength, is resistant to water, is easy to mold, and is cheap to make. But concrete’s biggest problem is that it’s easy to break because it does not resist cracking well, has low tensile strength, and cannot take a lot of stress. Researchers have been successful in enhancing the quality of cement composites by using fibers, admixtures, and other cementitious materials. When it comes to building objects, nanotechnology could open up a whole new world. Building materials have made nanosized materials that are used to make cementitious materials stronger and last longer. For example, they stop microcracks from starting and spreading. One of the most well-known graphene derivative nanomaterials is graphene oxide (GO), which has a lot of active oxygen-containing groups on its surface, outstanding mechanical properties, and thermal conductivity. Researchers have found that adding small amounts of GO in various dosages increases the flexural, tensile, and compressive strengths of cement paste and mortar. The majority of studies have looked at cement paste and mortar. There are few GO-concrete studies. One of the most characteristic graphene derivative nanomaterials, graphene oxide (GO), has a huge specific surface area, outstanding mechanical properties, thermal conductivity, and a lot of active oxygen-containing groups on its surface. Small amounts of GO at various dosages boost the flexural, tensile, and compressive strengths of cement paste and mortar, according to researchers. Most researches have examined cement paste and mortar. There are few GO-concrete studies. This article review paper will be useful for engineers and researchers investigating the impact of GO on mechanical qualities and advanced nanomaterials in cement-based materials like concrete. It will also be a point of reference for further research.
