Abstract
This paper investigates the effects of the different types and percentages of fiber reinforcements in
concrete on structures' design life. The primary parameter of the analysis is the tensile strength of concrete in
correlation with compressive strength in dependence on the type and quantity of fibers. Using fiber reinforcement
allows obtaining a pattern of evenly distributed micro-cracks instead of the usual system of localized individual
relative wide cracks and increases the durability of structures. The durability of concrete is evaluated from the
probability of the appearance of cracks through a comparative analysis of the results of experimental tests for
mixtures with different types and amounts of fibers. The subject of the analysis is also a mixture of concrete made
by increasing the coarse aggregate from recycled materials content and lower consumption of cementitious
materials as a green concrete option with improved resistance to aggressive environmental influences. The main
goal is to assess fiber-reinforced concrete (FRC) as cost-effective and green by increasing the recycled aggregate
content and lowering the consumption of cementitious materials. A comparative analysis of results gained by statistical and machine learning methods is performed for the influential parameters' assessment of the FRC
structures' design life.
