Análisis de propiedades mecánicas de hormigón translúcido con diferentes porcentajes de fibra óptica para uso en elementos estructurales.

Abstract

To carry out the present experimental work, it began with the collection of materials: stone aggregates from the city of Latacunga-San Buenaventura, Type GU cement, Viscomix 410L superplasticizer additive and 125 umm fiber optic. Next, the tests corresponding to the materials were carried out following INEN and ASTM standards in the Materials Testing Laboratory of the FICM. With the results obtained, we proceeded to dose using the optimal density method for traditional concrete and making corrections according to the ACI for self-compacting and translucent concrete. Regarding compression resistance, translucent concrete with 4 percent was the one that had the best performance compared to 3 and 5 percent, with values at 7, 14 and 21 days of 17.2, 24.4 and 32.4 Mpa respectively. With these results, the optimal percentage (4 percent) with which the beams were manufactured is determined. The flexural test indicates that the modulus of rupture at 7 and 14 days (1.81 and 2.69 Mpa) is lower than those obtained with traditional concrete (2.12 and 2.76 Mpa) and selfcompacting (2.81 and 3.99 Mpa), however, at 21 days (3.79 MPa) it has a flexural strength greater than traditional concrete (3.27 MPa) but less than self-compacting concrete (4.21 MPa). Finally, it follows that translucent concrete with the optimum percentage of 4 percent can be used as a structural material.
