In order to evaluate the construct ‎behavior of fiber-reinforced concrete with the natural and recycled aggregates, some of ‎its properties such as the triaxial compressive strength were theoretically studied. In ‎addition, different types of fibers and their chemical and physical properties, as well as ‎different types of fiber-reinforced concrete with and without the recycled aggregates ‎were dealt with for better recognition of fiber-reinforced concretes. In the following, ‎through performing the related tests for the determination of the triaxial compressive ‎strength on the concrete with polymer fibers containing the natural aggregates and ‎combination of recycled and natural aggregates as coarse aggregates, and the concrete ‎without fibers containing the natural aggregates and combination of recycled and ‎natural aggregates as coarse aggregates, the use of these aggregates has been studied. ‎The results showed that the use of synthetic fibers in concrete would lead to the ‎increase in tensile strength, and to some extent, in triaxial compressive strength. Also, ‎the decrease in tensile strength of the concrete with recycled aggregates can be ‎somehow compensated by adding the fibers, and besides, the addition of the fibers to ‎the recycled concrete would lead to the improvement of the mechanical properties of ‎the concrete such as the compressive strength, tensile strength, and also, the triaxial ‎strength‎. %U https://sciarena.com/article/investigation-of-the-effects-of-different-percentages-of-synthetic-fibers-on-triaxial-compressive-strength
