Abstract
Carbon nanotubes and carbon nanofibers exhibit several distinct advantages as a reinforcing material for cementitious composites, as compared to more traditional fibers. They exhibit significant greater strength and stiffness, which greatly improve the composites’ mechanical behavior. In this research, an experimental study of the mechanical characterization of cement based nanocomposite materials reinforced with carbon nanotubes is presented. The classic micromechanical approach for fiber reinforced composites was employed to develop predictive models for the modulus of elasticity of the nanocomposites. Results reveal a good agreement between the experimental and predicted values, when using the Benveniste model with disk like inclusions.
