| Abstract: | Through the experimental research on the 129 concrete specimens with the size of 100 mm×100 mm× 100 mmt,he volume fraction of steel fibert,he grade of concrete strength and different carbonization time were taken as variable parameters.This paper studied the influence of the volume fraction of steel fibert,he grade of concrete strength and different carbonization time on the splitting strength of steel fiber reinforced concrete.Furthermore,the reinforced mechanism of the steel fiber reinforced concrete under the action of carbonization was discussed.The study results showed that when the grade of concrete strength is higheri,t is benefit for steel fiber to the splitting strength of steel fiber reinforced concrete. |
