In this quantitative, descriptive and explanatory research with a quasi-experimental design, the influence of the addition of Sika Fiber Force - 48 synthetic macrofiber on the modulus of rupture of cement-sand concrete made only with fine aggregate was determined. The sample consisted of standard concrete specimens made with w/c ratio = 0.58, 0.63 and 0.68; and specimens of the experimental group made with the same water/cement ratio and three fiber dosages (7.5, 8.5 and 10 kg/m3). Descriptive and inferential statistics were applied. In light of the results, the following conclusions can be drawn: The addition of Sika Fiber Force 48, in all dosages of the experiment does influence the modulus of rupture of cement-sand concrete. The best results are obtained with the addition of 10kg/m3 of concrete mix, for the three A/C ratios of 0.58, 0.63, 0.68; however, the highest modulus of rupture found was 69 kg/cm2, corresponding to the ratio A/C = 0.58, having varied from 51 kg/cm2 of the standard concrete, which confirms the general hypothesis; however, the compressive strength for all the experimental A/C ratios were lower than those of the standard concrete, decreasing up to 20%.
