Effect of tire cords, steel and polypropylene fiber content on the fatigue response of cement-based mortars

Original language description

The subject of the study presented in this paper is to quantify the effect of fiber content on nthe mechanical and mainly fatigue response of fine-grained cement-based mortars. The reference ncement-based composite was without fibers. Three types of fibers were used as dispersed nreinforcement: tire cords (waste material), steel, and polypropylene. For each type of fiber, mixtures nwith varying reinforcement levels per volume were prepared: 0.0 % (reference composite), 0.5 %, n1.0 %, and 1.5 %. Prismatic specimens 40 mm × 40 mm × 160 mm were prepared and tested. A total nof 10 composite variants were investigated. The ages of the specimens for the static three-point nbending tests were 28 days, for the compression tests were 28, 120, and 275 days. While for the nfatigue tests, it was approximately between 110 and 180 days. The obtained compressive strength nvalues for the above-mentioned composite ages were approximated by a selected exponential function nand the results of the fatigue tests were standardized to a nominal age of 28 days using them. All used ntypes of reinforcement increase the strength values of the mortars even from the lowest fiber doses. nA positive effect of fiber dosage above 0.5 % on the fatigue behavior of mortars was shown only in nthe case of reinforcement with commercial steel fibers.
