Influence of experimental variables on the mechanical properties of steel fiber reinforced concrete (SFRC) in chloride degradation experiments: bibliographic review and statistical analysis

Abstract

This research aims to evaluate the effect of experimental variables in the study of chloride degradation of steel fiber reinforced concretes (SFRCs). The information was collected from different literary sources to be treated through Taguchi's experimental design and regression analysis. The results show that the most influential factors in the degradation of SFRCs by chloride are the load during degradation and the crack width, residual resistance, and maximum flexural load. However, others, such as the water/cement ratio, fiber volume, chloride concentration, and degradation time, showed little influence on the mechanical response of the SFRCs.
