Self Sensing Capability of Multifunctional Cementitious Nanocomposites
Carbon nanotubes (CNTs) exhibit excellent electrical properties and can be used to produce multifunctional nanocomposite cement based materials with exceptional self sensing capabilities. The self sensing behavior of cementitious nanocomposite materials, their ability to sense strain, stress and cracking, while achieving superior mechanical properties, can be closely related to the electrical and piezoresistive properties of the material. In this research, the piezoresistive behavior of novel multifunctional cementitious nanocomposites was investigated in order to determine the carbon nanotube electrical percolation threshold. Carbon nanotube cement composites with different percentages of CNTs for w/c = 0.485 were prepared. The electrical resistance was initially measured using direct current (DC), followed by piezoresistivity measurements under cyclic compressive loading. The 4-pole method was employed for both conductivity and piezoresistivity measurements. Results demonstrate that carbon nanotubes can be used to successfully create a conductive network for stress/damage detection in advanced, multifunctional cement based nanocomposites.
