Paper Abstract

In this paper, the vibration damping capacities of cement-based matrix with some additions of multi-walled carbon nanotubes (MWNTs) are investigated with free vibration testing method in an elastic system. The experimental results show that there are positive effects on the critical damping ratio ζ of the cement-based matrix with small amount MWNTs additions. The nanotubes increase the damping ratios (ζ) of the MWNTs reinforced cement composites due to the contribution of excellent frictions among multiple inter-tubes and multi-walled carbon nanotubes-matrix large interface area to damping. The flexural and compressive strength tests of those are subsequently implemented. Results indicate that the nanotubes has the reinforcing function to cement on the flexural strength in some degree, while has the negative impact on its compressive strength.
