ABSTRACT In this thesis the emphasis is on concrete technology, as well as the use of non-conventional materials, for the present investigation that aggregates were used from the Bazán quarry (Bambamarca road 1.5 km). For this, the physical-mechanical characteristics were determined. of the aggregates according to the specifications NTP 400.037 / ASTM C33, to then make the design of mixtures of the standard concrete using the method of the ACI 211 committee using Type I cement, likewise Furcraea Andina fiber was incorporated as an additive in different percentages ( 0.75%, 0.50%, 0.25%) with respect to the fine aggregate, to later determine its influence on the concrete strength f'c = 210 kg · cm-2, through mechanical tests at 7, 14, 21 and 28 days, verifying that at 0.75% fiber of Furcraea Andina with respect to the weight of the fine aggregate, tested at 28 days show a considerable decrease in the resistance to axial compression of the concrete, decreasing the maximum effort by 51.28%, the results of the tests of axial compression of the concrete made with addition to 0.50% of Furcraea Andina with respect to the weight of the fine aggregate, tested at 28 days, show a decrease in the resistance to axial compression of concrete, decreasing the maximum effort by 30.02%, because each processed specimen contains a lot of fiber, so the cement paste does not adhere correctly to the aggregate, which is observed when the concrete samples are tested to axial compression, what makes it fail is the cement paste; the results of the axial compression tests of concrete made with addition to 0.25% of Furcraea Andina with respect to the weight of the fine aggregate, tested at 28 days, show a decrease of 14.64% in the resistance to axial compression of the concrete, due to that each processed specimen contains less fiber than the other dosages, so the cement paste allows it to adhere correctly to the aggregate, however it can not overcome the standard sample, which is observed when the concrete samples that are tested by axial compression , concluding that the hypothesis is not fulfilled
