description This document contains an analysis of the flexural strength and compressive strength of portland cement mortars reinforced with polypropylene fibers obtained from polypropylene straps, polypropylene straps were obtained by taking advantage of waste from logistics operations and packaging. Straps are the most widely used product both for sealing boxes and for tying pallets for national and international transport in Colombia. After obtaining the bands, the fibers were extracted, which were obtained by grouping several bands in a press, where the height of the jaw was adjusted for an adequate depth of cut and subsequently cut by a thin blade. To carry out the study, 3 types of test tube molds were used in which the mortar mixture with polypropylene band fiber was poured. In addition, samples of mortar without fiber were prepared to make the respective comparisons. The samples had 28 days of curing under water and were evaluated with the guide of the NSR-10 standard, obtaining results of compressive strength of 9.06 MPa and flexural strength of 3.04 MPa, for mortars with 0 , 9% PP fiber. Despite the fact that mortar containing 0.9% polypropylene fiber aggregate has lower mechanical properties than mortar without fiber, it classifies within the NSR-10 standard because it requires a minimum resistance of 8.9 MPa compression. Under flexural conditions, the material fractures when reaching a load close to 3 MPa, however, it is observed that the material continues to support load due to the action of the PP fibers that act as a safety device that prevents an abrupt failure.

Los zunchos son el producto más utilizado tanto para el sellado de cajas como para el amarrado de estibas para transporte nacional e internacional en Colombia. Posterior a la obtención de los zunchos se procedió a la extracción de las fibras, las cuales se obtuvieron mediante la agrupación de varios zunchos en una prensa, donde se ajustaba la altura de la mordaza para una adecuada profundidad de corte y ser posteriormente cortadas por una cuchilla delgada. Para llevar a cabo el estudio se utilizaron 3 tipos de moldes para probeta en las cuales fue vertida la mezcla de mortero con fibra de zunchos de polipropileno. Se elaboraron, además, muestras de mortero sin fibra para hacer las respectivas comparaciones. Las muestras contaron con 28 días de curado bajo agua y se evaluaron con la guía de la norma NSR-10, obteniendo resultados de resistencia a la compresión de 9,06 MPa y resistencia la flexión de 3,04 MPa, para los morteros con 0,9% de fibra de PP. A pesar de que el mortero que contiene 0,9% de agregado de fibra de polipropileno tiene propiedades mecánicas inferiores a las del mortero sin fibra, clasifica dentro de la norma NSR-10 debido a que ésta pide cómo mínimo 8,9 MPa de resistencia a la compresión. Bajo condiciones de flexión, el material se fractura al llegar a una carga cercana a los 3 MPa, sin embargo, se observa que el material sigue soportando carga por acción de las fibras de PP que actúan como un seguro que evita una falla abrupta.This document contains an analysis of the flexural strength and compressive strength of Portland cement mortars reinforced with polypropylene fibers obtained from polypropylene straps.
