The influence of modified carbon nanotubes on the performance of bridge concrete


Lanzhou Jiaotong University, China


The effect of plasmon modified carbon nanotubes (P-CNT) on the strength properties of concrete has been investigated. The results show that when the content of P-CNT reaches 0.3 %, the compressive strength and crack strength of the samples reach the maximum value, and then show a downward trend. The PI electrons on the surface of the P-CNT will improve the resistance stability under the action of the external electric field. It can be seen that the compressive strength and crack strength of concrete are improved after the addition of plasmon-modified carbon nanotubes, and the anti-crack strength is improved more significantly.
