摘要
Abstract
As a composite reinforcement,carbon nanofibers can improve the strength,elasticity and durability of concrete.Prestressed concrete materials with different mass fractions of carbon nanofibers were added to prepare carbon nanofibers modified prestressed concrete materials,and the enhancement effect of carbon nanofibers in prestressed concrete structures was explored.The results show that with the increase of the content of carbon nanofibers,the compressive strength,flexural strength,and splitting tensile strength of the samples increase first and then decrease.The wear loss of prestressed concrete shows a trend of decreasing first and then increasing.When the content of carbon nanofibers is 0.3%,the porosity and wear of prestressed concrete are the lowest,which are 26.23%and 1.2 kg/m2 respectively.Therefore,the proper addition of carbon nanofibers(mass fraction of 0.3%)can effectively improve the mechanical properties and wear properties of prestressed concrete.关键词
