    Estudio comparativo de la resistencia a flexión de vigas convencionales con vigas reforzadas con resina poliester liquida

    The present research work consists of working with different conventional concretes and replacing the fine aggregate materials and water with similar amounts of liquid polyester resin. Then, it is expected that with these new polymer concretes the flexural strength will increase. In order to establish the dosages of conventional concrete, the A.C.I. method was used, additionally it was corroborated with laboratory tests for each of the stony materials, the tests carried out were: granulometry test, apparent density, compacted and loose, real density, capacity absorption, real density of the cement and the concrete slump test. With the specimens the compression test was carried out at 7, 14 and 21 days after curing, thus obtaining the strengths of 210, 240 and 280 kilograms per square centimeter. In addition, the resin helps conventional concrete to improve its chemical and mechanical properties, thus forming polymeric concrete. After that, with the new concrete obtained, the flexural strength test was carried out with a load applied to thirds of the span in each of the manufactured beams. Finally, using the Mander and Park method, the calculation of the MomentCurvature diagram of each beam of both normal and polymeric concrete was carried out, to perform an analysis of each of the curves obtained and establish that there is an increase in resistance to the flexion when working with resin since the modulus of rupture is higher compared to that of the other specimens.
