Abstract
This paper utilizes finite element (FE) models to study the improvement in tensile strength and ductility of cement when using carbon nanotubes (CNTs) as reinforcement. Nanoscale and macroscale models are used to investigate the interfacial bond behavior of an individual CNT embedded in cement matrix and the flexural response of a CNT/cement composite beam, respectively. Experimental test results of CNT/cement composite beams are used to calibrate the numerical models. The results prove that the FE models are successful in capturing the degradation in the CNT/cement bond strength and its effect on the flexural strength, ductility, and toughness of the composite.
