Abstract: Structural Health Monitoring (SHM) of concrete structures is now a very important technology in order to ensure that the structure is safe and sound. But there are many disadvantages in SHM. Hence it calls for much better and a very simple approach, therefore it’s our responsibilities as Structural Engineers to find solutions to these quagmires. This research concentrates on finding solution to the limitations of using sensors by making use of the advanced Nanotechnology. Carbon Nanotubes are used as a Self-Sensing tool to achieve Intrinsic Self-Sensing ability of the concrete or cement mortar. The indigenous electric resistivity parameter of Carbon Nanotubes is made use of effectively in developing the Intrinsic Self Sensing ability of the concrete or cement mortar. Copper rods are used to achieve resistance property of the CNT’s. Two probe method is made use of for the connections to get the resistance. Resistance is tabulated using multimeters. And the results are tabulated. Experimental results show excellent electric resistivity response when Carbon Nanotubes are used in the cement mortar specimens.
