- Abstract:
-
Through the experimental study of 43 groups of 129 concrete cubes of 100mm×100 mm × 100mm, the changes of bending properties of steel fiber concrete with different volume rates and different strength grades at different carbonization ages were studied, and the influence mechanism of steel fiber on the flexural strength of concrete was discussed. The test results show that when the strength grade of concrete matrix is high, with the increase of carbonization age and steel fiber volume rate, the bending performance of concrete after carbonization is significantly improved, and the relative flexural strength of steel fiber concrete with matrix strength grade C30 and volume rate of 1.0% and 2.0% carbonization for 3 d, 7 d, 14 d and 28 d, respectively, the relative flexural strength is 0.98, 1.11, 0.91, 1.21 and 0.92, 1.24, 1.23 and 1.39, respectively.
