In this paper, tensile properties of a high-performance fiber reinforced lime-based mortar is experimentally investigated using four-point bending test. In the study, we consider several sets of the mortar with two types of the matrix (pure lime, lime-metakaolin) and two types of polyvinyl alcohol fibers in four volume fractions (0.5÷2.0%). As the reference, we consider two sets of specimens made of plain mortar without reinforcement. The main investigated parameters are cracking strength (initiation of the first crack), ultimate tensile strength and Young’s modulus of elasticity. Moreover, we deal with the character of stress-displacement diagram, whether after initiation of cracking occurs softening or the response has hardening character and the specimen breaks in multiple cracking.
