Abstract EN
This paper investigates the elastic (Young’s) modulus of carbon Nanotube- (CNT-) reinforced cement paste using 3D and axisymmetric models using Abaqus software.
The behavior of the CNT and the cement matrix was assumed to be fully elastic while the cohesive surface framework was used to model the interface.
To investigate the effect of fiber waviness on the value of the elastic modulus, 3D models were developed assuming different distributions of fibers.
The results obtained using the 3D model were compared to those obtained using the simplified three-phase axisymmetric model which consists of one single CNT aligned in the center of composite unit cell, an interface, and cement matrix.
A parametric study was then carried out using the axisymmetric model to study the role of the interface in the composite elastic modulus without accounting for the presence of the interfacial transition zone (ITZ or interphase).
The results showed that the CNTs waviness significantly reduced their reinforcing capability in the cement paste.
On the other hand, the results obtained using the axisymmetric model were found to be in good agreement with those obtained using the 3D model.
Moreover, the results of the parametric study showed that the interface properties significantly affect the composite elastic modulus and alter its behavior.
