Evaluation of the Flexural Performance of Fiber Reinforced Mortar with Low Fiber Content

Abstract:

This study investigates the relationship between the amount of fiber reinforcement and flexural tensile capacity by evaluating the degree of dispersion and the fiber reinforcement effect in mortar mixes with low fiber contents (lower than 0.2%) in order to derive solutions enabling to improve the tensile performance of mortar with low contents in macro fibers. The results show that a certain degree of improvement of the toughness is achieved even in the case of fiber reinforced mixes with low fiber contents and that the variation of the toughness capacity is sensitive to the degree of dispersion of the fibers.
