Abstract
- The effect of the steel fibre distribution on concrete is significant, studies regarding the distribution characteristics of steel fibre are of great significance for the application of steel fibre-reinforced concrete (SFRC). Based on different mechanical test results, this paper aims to propose a reliable analysis method for more efficient evaluation of steel fibre distribution by using image processing and the inductive test to do comparison analysis on the steel fibre distribution in different concrete specimens. Firstly, the results of image processing and inductive test of different type of SFRC cubic specimens was analysed to obtain the steel fibre distribution, and a formula for rapid calculation of fibre content was proposed. Then, the influence of steel fibre distribution on the mechanical properties of SFRC was analysed by combining double punch test and three-point bending test results. Finally, the high similarity of the spatial distribution of steel fibre is analysed by the inductive test and image processing, which are reflected by the phase coefficient, and the applicability of these two methods are compared and evaluated.
