In order to explore the effects of different carbon fiber content on the mechanical properties and frost resistance of concrete under freeze-thaw conditions.Carbon fiber concrete samples with 0,0.3％,0.6％,0.9％and 1.2％content were prepared in the experiment,and the freeze-thaw cycle test,compressive test and splitting test were carried out.The compressive strength,tensile strength,mass loss rate and relative dynamic elastic modulus of concrete with different carbon fibers under freezethaw condition are further analyzed.The results of this study can provide some reference for the promotion of carbon fiber reinforced concrete in pavement engineering in frozen areas.
