Abstract
To study the micro-structural characteristics of fiber concrete and the mechanism of fiber concrete crack resistance, the micro-structural morphology of fiber concrete specimens was observed and analyzed in this paper by using the electron microscope scanning technique. Based on the research group's previous studies on axial tensile tests of steel fiber and nano-fiber concrete specimens with different fiber admixtures, samples were taken from the fiber concrete specimens with different fiber admixtures. This paper focuses on the effect of different steel fiber doping and nanofiber doping on the micro-structural characteristics of fiber concrete. The results show that the micro-structural compactness of the fiber concrete specimens with 1.5% steel fiber and 0.1% nanofiber doping is optimal, and the optimal doping rate is consistent with the doping rate with the optimal effect of crack width control in the fiber concrete axial tensile test.
