This paper investigates the behaviour of hardened cement paste reinforced with multi-walled carbon nano-tubes (MWCNTs) and Nano-SiO2 (NS). In these composites, the percentage of MWCNTs was fixed at 0.75% by weight of cement, while the percentage of NS was fixed at 0.5% by weight of cement. Dispersion of both MWCNTs and NS was carried out using ultrasonic energy method. The novel nano-composite specimens developed were tested for compression and flexure in order to evaluate their mechanical properties such as compressive strength, flexural strength, toughness and ductility. These results were then compared with the results of plain cement control beams. Scanning electron microscopy was conducted to examine the bond between the MWCNTs and the cement matrix.
