Abstract: 

The influence of modified carbon nanotubes (P-CNT) and unmodified carbon nanotubes (CNT) on the compressive strength and crack strength of concrete materials under condition of the fixed water-cement ratio was studied. The results show that, when the water-cement ratio is 0.4, the optimal content of plasma carbon nanotubes (P-CNT) is about 0.3 %, the appropriate quantity of the plasma carbon nanotubes can be evenly dispersed in the concrete material, and the mechanical properties of concrete can be effectively improved.

Keywords: 
multiwalled carbon nanotubes, concrete, water cement ratio, mechanical properties.
