Reduced graphene oxide sheets (rGO) have unparalleled physical characteristics that make them effective reinforcing materials. This article explore the effect of rGO on mechanical properties, pore size distribution, micro-structural characteristics and self-sensing properties of the hardened cement paste. The rGO were introduced to net cement paste at different percentages of 0, 0.01, 0.02, 0.03, 0.04 and 0.05 wt% of cement. Compressive strength was measured at 28 days of hydration. The rGO sheets were characterized by high-resolution transmission electron microscope (HRTEM) and Raman spectroscopy. The rGO/cement composites were characterized by Thermo-gravimetric analysis (TGA) pore size distribution and scanning electron microscopy (SEM). Finally; peizoresistive measurements have been performed to study the self-sensing properties of rGO/cement composites. The obtained results revealed that, considerable enhancements in compressive strength by about 27 and 38% were achieved by incorporating 0.04 rGO and 0.05% rGO, into cement matrix respectively. The integration of rGO into cement has significantly reduced the pore size of the rGO–cement composites and led to a considerable improvement in the microstructure. Based on the obtained results, the rGO-cement composites can be efficiently used as piezoresistive sensors.
