In the present research work, the influence on the physical and mechanical properties of the mortar is disclosed by applying a fixed percentage of coconut tow fiber of 2 different lengths, based on the weight of the fine aggregate that is required in the mixture. The proportion used for this research was 1 cement: 2.98 sand with a water / cement ratio 0.56. For the preparation of the mortar, fine aggregate from the UNICON quarries, SOL Portland Type I Cement and drinking water from the network of the Laboratory No. 1 of Materials Testing “Ing. Manuel Gonzales de la Cotera”, located on the campus of the National University of Engineering. Likewise, the tests corresponding to the aggregates were carried out for the mixture design. In the mixtures, a fixed percentage of 0.5% of 1cm and 2cm coconut tow fiber was added, based on the weight of the fine aggregate; Fluency, unit weight of fine aggregate, axial compression of cubes, diagonal compression in walls, bending forces in prisms were carried out, applying the standard NTP 334.057: 2019, NTP 400.017: 2020, NTP 334.051: 2019, NTP 399.621: 2004 and NTP 334.120: 2016 respectively. Upon completion of the trials, it was possible to conclude that coconut tow fiber, if it influences conventional mortar, adversely affects as well as favorably. The workability of the mortar with the addition of coconut fibers was reduced by 36.07% and 47.15%, because the fiber tends to absorb water. In the Unit Weight of the fine aggregate of the mortar, it is favored, since the fiber does not tend to increase weight because it is an extremely light material. On the other hand, the result in the diagonal compression tests of the wall with the addition of fiber of length of 1cm and 2cm, are reduced to 81.25% and 75%, with respect to the pattern. In the same way, in the resistance to compression of mortar cubes, due to internal failures produced by poor compaction in the mixture, making the mortar with the addition of fiber of 1 cm and 2 cm have an inferiority of 42.23% and 21.14% with respect to the pattern. It is worth mentioning that the longer the fibers were, the less cracking was noticeable. Finally, the resistance to bending, the favoring was appreciated when increasing the length of the fiber, due to the cohesion generated in the mixture. Therefore, it is concluded that the addition of coconut tow fiber did influence the physical and mechanical properties of conventional mortar, as well as, favorably or vice versa.
