摘要：In order to investigate the influence of carbon nanofibers (CNFs) on the strength and internal pore structural characteristics of concrete, the carbon nanofibers reinforced concrete (CNFC) specimens with the content of 0%, 0.1%, 0.2%, 0.3% and 0.5% were prepared. The characteristics of the internal pore structure of specimens in each group were analyzed by the method of mercury intrusion porosimetry (MIP). The results show that the appropriate amount of CNFs has a significant enhancement effect on the strength of concrete, but the excessive amount of CNFs (0.5%) will weaken the performance of concrete; CNFs can effectively reduce the total pore volume and average pore size of concrete, and the internal pore structure of concrete can be improved reasonably.
