This paper reports on research aimed at investigating the reinforcing effects of graphene nanoplatelets (GNPs) in cement composites. Nanoreinforced cement mortar cubes were prepared using surfactant-coated GNPs. The dispersion and embedment of GNPs in the cement matrix were verified based on evidence from compression strength tests and scanning electron microscopic imaging. Results from fracture mechanics tests on notched beams were then used to evaluate the effect of incorporating well-dispersed, surfactant-coated GNPs on the flexural strength and stiffness of cement paste. 3D digital image correlation measurements were used to study the morphology and evolution of the fracture process zone in plain and GNP-reinforced cement paste.
