TLDR
In this article, the effect of adding steel fibers with different lengths and diameters on the mechanical properties of concrete for three values of concrete strength was investigated, and the results indicated that the addition of different content and lengths of steel fiber with increasing water-to-cement ratios caused significant change in concrete, with an increase of about 10-25% in compressive strength and about 31-47% in direct tensile strength.About:

Machine learning-based prediction for compressive and flexural strengths of steel fiber-reinforced concrete
TL;DR: The water-to-cement ratio and silica fume content were the most influential factors in the prediction of compressive strength of SFRC, whereas the silicafume and fiber volume fraction most strongly influenced the flexural strength.
