Graphite particles (&lt;20 μm) were functionalized using a subatmospheric 13.56 MHz radio frequency-excited oxygen plasma followed by liquid-phase exfoliation to produce pf-MLG with a high aspect ratio (&gt;2585) with &lt;20 graphene layers. The exfoliated graphene also exhibited high dispersibility in water after plasma functionalization without the use of surfactants. The pf-MLG nanoflakes were incorporated into a cement mixture with 0.1 and 0.5 wt% pf-MLG loading. A 56% increase in compressive strength of cement mortars was achieved for the 0.5 wt% pf-MLG after 28 days curing. This is attributed to the strong interfacial interaction between graphene and the cement matrix and the promotion of hydration. The highly scalable process of pf-MLG-reinforced cement will make a positive impact on the environment, especially in the construction industry.</style></abstract></record></records></xml>
