A review: The effect of graphene oxide on the properties of cement-based composites

Qureshi, Tanvir S; Panesar, Daman K

Abstract

Graphene oxide (GO) is a recently invented 2D nanoplane fiber. GO is typically produced via the chemical oxidation and exfoliation of graphite. It contains active functional groups on its nanoplane surface, and these groups play a major role during the cement hydration process. Preliminarily, the hydration properties of GO–cement composites have been found to result in a higher hydration rate, which affects both the water demand and workability of the composites. Some authors have also reported that reinforcing the cement matrix with GO results in the formation of calcium silicate hydrate (C–S–H) gel in the micropores, thereby enhancing the resultant composite’s mechanical properties. Markedly few studies have examined the durability of GO–cement-based composites. This paper presents a critical review of the functionalities and effects of GO in cement-based composites, including its effects on hydration, workability, transport properties, the evolution of mechanical properties, and durability. This review also covers literature reports related to the life-cycle cost and the carbon footprint of such cement composites.
