Analysis of the Mechanical Properties of Mortar Reinforced with Long Unidirectional Alfa Fibers in Different Curing Conditions

摘要

A mortar reinforced with long unidirectional alfa and sisal fibers was considered. Laminated mortar specimens with different fiber volume fractions were prepared, and their mechanical properties were investigated. The optimum fiber volume fraction was found to range between 0.8 and 1.1% and depended on curing conditions. In the case of alfa fibers, the flexural strength of mortar specimens increased by about 27%. It is concluded that alfa fibers can be an alternative to synthetic fibers.
