Compressive Strength of Lime-Based Mortars Reinforced by Micro Glass Fibers

Abstract:

Glass fiber-reinforced lime-based mortars have been studied. Two different fiber reinforcement amounts were used as an addition to the mixtures. Compressive strength and post-cracking behavior of mortars were observed and compared with reference mixture without any reinforcement (marked R). The fibers were added in the amount of 1.8 kg/m³ (mortar samples MA) and 93.75 kg/m³ (mortar samples MB). Destructive compression tests were chosen to compare the performance of the individual mixtures. The maximum compressive strength reached during the testing was the highest for reference samples, while those samples together with MA exhibited the elastic-brittle behavior. Only MB had post-linear hardening behavior and after reaching the maximum compressive strength a slow softening was present.
