Influencia Del Dióxido De Titanio En El Concreto Permeable Con Efecto Fotocatalizador
Resumen
El objetivo es determinar la influencia del dióxido de titanio en el concreto permeable con efecto fotocatalizador. La población fue de 63 probetas cilíndricas de 15 x 30 cm y 42 probetas de 9.5 x 15 cm de concreto; teniendo como muestra probetas con diseño convencional (sin adición de titanio), y por los diseños de mezcla utilizando dióxido de titanio, considerando el estado de dióxido de titanio y el porcentaje de este sobre el concreto. Se determinó que los especímenes con 1,5% de TiO2 en fase anatasa presentaron buenos índice de coeficiente de permeabilidad en relación de la muestra patrón, la mayor resistencia a la compresión se presenta en la muestra con 1.5% de TiO2 en fase rutilo, siendo seguidos por los especímenes con 5,5% de TiO2 en fase rutilo y 1.5% en la fase anatasa que también presentaron buenos índice de resistencia a la compresión; la mayor propiedad fotocatalíticas se presentaron en los especímenes con 1,5% de TiO2 en fase anatasa. Se concluyó: la dosificación de 1.5% en la fase anatasa es la más recomendable dado que muestra buen índice de permeabilidad, así como mejoras significativas en la resistencia a la compresión del concreto y en la propiedad fotocatalítica.
