    Abstract
  • In order to study the effect of strain rate (loading rate) and multi-walled carbon nanotubes (MWCNTs) content on the mechanical properties, energy evolution law and damage failure characteristics of MWCNTs-reinforced concrete samples, the RMT-150B rock mechanics test system was used to carry out a series of uniaxial compression tests on MWCNTs-reinforced concrete samples with different content of MWCNTs under different strain rates. The results show that the ductility of MWCNTs-reinforced concrete samples increases with the increase of the content of MWCNTs. When the strain rate is constant, the uniaxial compressive strength of the MWCNTs-reinforced concrete with 0.10% MWCNTs content is the highest; when the content of MWCNTs is constant, the uniaxial compressive strength of the MWCNTs-reinforced concrete samples reaches the maximum under strain rate of 5×10–3 s–1 (0.5 mm/s); when the strain rate is large, the mean value of the energy dissipation of MWCNTs-reinforced concrete accounts for 28.29% of the total energy at the peak stress. When the strain rate is small, the energy dissipation phenomenon in the pre-peak stage is significant, and the mean proportion of dissipated energy at the peak stress is as high as 37.34%. When the strain rate and MWCNTs content are small, the energy absorbed by the MWCNTs-reinforced concrete before failure is largely transformed into dissipative energy, and the energy release rate of the samples after peak stress is small, which is characterized by mixed failure of local tension and shear. When the strain rate and MWCNTs content are large, the energy absorbed by the MWCNTs-reinforced concrete before failure is mainly stored as releasable elastic strain energy, and the energy release rate of the concrete samples is faster at failure, and the MWCNTs-reinforced concrete samples are relatively broken at failure, showing the characteristics of impacted damage to a certain extent.
