This research explores the feasibility of using graphene oxide (GO) as an additive to improve cementitious composite strength. A cement composite was tested for its compressive strength and pore structure, where 0.025wt percent of cement unit weight was substituted by GO. The optimal replacement ratio was previously defined as this. Comparative studies were performed on cement composites substituted with standard cement additives such as fly ash (FA), silica fume (SF), Nano-silica (NS) and ground granulated blast-furnace slag (GGBS). The cementitious composites substituted with GO had a slightly lower air content, but had compressive strength which was 10.6–41.5 percent higher than that of the plain mixture, and also higher than that obtained with other cement additives. The toughness and mechanical properties of hardened cement composites can be improved by improving the structure and enhancing the cement matrix's paste – aggregate interface; this is usually accomplished with additives and admixtures. Analysis of the Pore structure showed that most pores were microspores with diameters not exceeding 2.5 nm; this improved the strength.
