Evaluation of the Compressive and Flexural Strength of Permeable Concrete with Substitution of Fine Aggregate by Glass Fiber in Urban Roads of the Peruvian Highlands.

Rigid permeable pavements are draining structures that allow the filtration and management of water in a sustainable manner. Unlike traditional systems, this type of material would avoid problems or failures due to surface runoff, ponding, and runoff. However, due to this quality his stamina tends to drop. For this reason, a concrete mix was developed with the use of fiberglass to increase its mechanical properties. The following work shows the analysis and comparison of conventional rigid permeable concrete mixes and with the addition of 1%, 2% and 3% fiberglass instead of fine aggregate, designed with the ACI 255R-10 standard. The results show that the compressive behavior, with respect to the base, increases by 1% and decreases for 2% and 3% (Base concrete: 215.55, Mix 1%: 262.25, Mix 2%: 252.65 and Mix 3%: 235.20). In the same way, the results of flexural resistance show that the base concrete is 30.6 kg/cm2 and all exceed it, but the one that obtained the most resistance is mix 1 with 35.6 kg/cm2, which confirms its influence. of fiberglass augmentation. On the other hand, in the physical property of permeability, the results show more infiltration speed in mix 3 with 1.18 cm/s, where it can be deduced that it is due to the decrease in fine aggregate.
