Resumen
La presente investigación tiene por objetivo aplicar vidrio reciclado triturado en diseños de mezcla
de concreto en reemplazo del agregado grueso, para mejorar la resistencia del concreto.
Se usará un muestreo no probabilístico se ensayarán muestras a los 7, 14 y 28 días. Conforme a
la norma técnica NTP 339.034 se fabricará mínimo 3 probetas de concreto para las diferentes
edades y para concretos estructurales de f’c=175 kg/cm2 y f´c=210 kg/cm2, considerando
diferentes porcentajes de uso de vidrio triturado. Se tomará los resultados de los mejores
especímenes. En este caso se propone porcentajes de 10, 20 y 30%, con lo cual sería necesario
ensayar un total de 54 probetas con vidrio triturado en reemplazo del agregado grueso, y 18
probetas para concretos convencionales.
Se observó que para concretos f’c= 210 kg/cm2 con 10 % de vidrio reciclado triturado, los valores
promedios de resistencia a la compresión a los 7, 14 y 28 días de curado, resultan los valores de
180.39 kg/cm2, 223.88 kg/cm2, y 260.36 kg/cm2 respectivamente, que en porcentajes con
respecto a la resistencia requerida equivalen al 85.90 %, 106.61 % y 123.98 % respectivamente.
Se observó que para concretos f’c= 175 kg/cm2 con 10 % de vidrio reciclado triturado, los valores
promedios de resistencia a la compresión a los 7, 14 y 28 días de curado, resultando los valores
de 149.01 kg/cm2, 180.53 kg/cm2, y 212.59 kg/cm2 respectivamente, que en porcentajes con
respecto a la resistencia requerida equivalen al 85.15 %, 103.16 % y 121.48 % respectivamente.
Se concluye que el porcentaje óptimo que mejora la resistencia en el diseño de mezcla es al aplicar
10% de vidrio reciclado triturado en reemplazo del agregado grueso. Obteniendo una resistencia
mayor a la del diseño patrón, logrando el 123.98% en diseños de mezclas de concreto con f’c=
210 kg/cm2, y el 121.48% en diseños de mezclas de concreto con f’c= 175 kg/cm2.
The objective of this research is to apply crushed recycled glass in concrete mix designs instead of coarse aggregate, to improve the resistance of concrete. A non-probabilistic method will be used, samples will be tested at 7, 14 and 28 days. In accordance with the NTP 339.034 technical standard, a minimum of 3 concrete specimens will be manufactured for the different ages and for structural concrete of f'c=175 kg/cm2 and f'c=210 kg/cm2, considering different percentages of use of crushed glass. The results of the best specimens will be taken. In this case, a percentage of 10, 20 and 30% is proposed, with which it would be necessary to test a total of 54 test tubes with crushed glass instead of coarse aggregate, and 18 test tubes for conventional concrete. It was discovered that for concrete f'c= 210 kg/cm2 with 10% crushed recycled glass, the average values of compressive strength at 7, 14 and 28 days of curing, resulting in values of 180.39 kg/cm2, 223.88 kg/cm2, and 260.36 kg/cm2 respectively, which in percentages with respect to the required resistance are equivalent to 85.90%, 106.61% and 123.98% respectively. It was discovered that for concrete f'c= 175 kg/cm2 with 10% crushed recycled glass, the average values of compressive strength at 7, 14 and 28 days of curing, resulting in values of 149.01 kg/cm2, 180.53 kg/cm2, and 212.59 kg/cm2 respectively, which in percentages with respect to the required resistance are equivalent to 85.15%, 103.16% and 121.48% respectively. It is concluded that the optimal percentage that improves the resistance in the mix design is when applying 10% of crushed recycled glass instead of the coarse aggregate. Obtaining a greater resistance than the standard design, achieving 123.98% in concrete mix designs with f'c= 210 kg/cm2, and 121.48% in concrete mix designs with f'c= 175 kg/cm2.
