Research progress on properties of cement-based composites incorporating graphene oxide

Abstract Graphene oxide (GO) is a two-dimensional derivative of graphene material, with carboxy, hydroxy group functional groups at the middle sheets, and oxygen-containing sheet edges. It has multiple advantages, such as high strength, hydrophilicity, strong reactivity. With development construction materials, GO been widely used nano-reinforced material in cement-based composites (CBCs). Based on large amount relevant literature, preparation dispersion behavior GO-reinforced CBC are summarized. Besides, impact workability, volume stability, mechanical performance, durability discussed. Moreover, influencing mechanism hydration expounded. From findings this review, following conclusions can be drawn: fluidity will decreased when evenly dispersed cement slurry, which results loss workability CBC. Meanwhile, addition improves stability CBC, while tensile, compressive, flexural strengths all improved to varying degrees. The improvement mainly reflected corrosion resistance permeability resistance. In addition, problems existing current research summarized future perspectives put forward. review work article could offer important guidance for further implementation GO-doped practical engineering.
