Re-aggregation of graphene oxide (GO) in cementitious solutions compromises the mechanical enhancement of cement composite. We chemically functionalized GO via triethanolamine (TEA), the removal of COC groups on basal planes and the attachment of extra OH groups on edges promoted its dispersibility during hydration and in cement paste. When incorporated into cement, TEA-GO provides more nucleation sites due to the better dispersion, further promoting the hydration degree. TEA-GO enhanced the compressive strength and flexural strength by 9.4–31% and 8.1–36.7% respectively, which was significantly higher than that of GO(4.1–17.2%; 7.8–20%).
