Mechanism of the Modified Carbon Nanotubes Toughening DSP Cement Mortar

Abstract:

The analysis is made for the modification of multi-walled carbon nanotubes and the mechanical properties and microstructure of the modified carbon nanotubes toughening DSP cement mortar, the existence and toughening effect of modified carbon nanotubes on the fracture surface of materials were analyzed. Results shows that, the surface of the carbon nanotubes in the sample is covered with cement hydration products, with the carbon nanotubes in drawing state on the fracture surface and both ends of the tube connected firmly with cement materials, thus carbon nanotubes improve the toughness of materials effectively.
