Resumen
La industria de la construcción se encuentra en búsqueda de crear mezclas de
concretos y morteros eficientes, rentables y ecológicas. Por lo tanto, se han
encontrado en diferentes materiales como lo son; la ceniza volante y el polvo de
vidrio; una alternativa prometedora para mejorar los atributos de estas mezclas.
Este proyecto investigativo se basó en realizar una sustitución parcial de cemento
por ceniza volante y de arena por polvo de vidrio en mezclas de morteros, con el
objetivo principal de analizar los efectos de la implementación de la ceniza volante
y el polvo de vidrio en mejoramiento de la resistencia mecánica, la durabilidad y el
comportamiento del mortero. En el presente estudio se realizaron 18 especímenes
de 50mm × 50mm × 50mm; 9 para una prueba control (PC) y los 9 restantes para
la mezcla que tiene la sustitución de la ceniza volante y el polvo de vidrio (T1). Con
estos cubos realizamos ensayos en estado fresco (trabajabilidad, densidad en
estado fresco) y en estado endurecido (compresión a los 3 y 14 días, adsorción por
capilaridad, densidad en estado endurecido); se elaboró un análisis detallado de
cada uno de los ensayos elaborados; resaltando que la mezcla con inclusión de
ceniza volante y polvo de vidrio presentaron una reducción en la resistencia a la
compresión en comparación con la PC. Sin embargo, la T1 presento atributos como
menor absorción por capilaridad lo que indica que es una mezcla con baja
porosidad
The construction industry is seeking to create efficient, profitable and ecological concrete and mortar mixtures. Therefore, they have been found in different materials such as; fly ash and glass dust; a promising alternative to improve the attributes of these mixtures. This research project was based on carrying out a partial replacement of cement with fly ash and sand with glass powder in mortar mixtures, with the main objective of analyzing the effects of the implementation of fly ash and glass powder in improving the mechanical resistance, durability and behavior of the mortar. For this investigation, 18 specimens of 50mm × 50mm × 50mm were made; 9 for a control test (PC) and the remaining 9 for the mixture that has the replacement of fly ash and glass powder (T1). With these cubes we carried out tests in the fresh state (workability, density in the fresh state) and in the hardened state (compression after 3 and 14 days, adsorption by capillarity, density in the hardened state); A detailed analysis of each of the tests carried out was carried out; highlighting that the mixture with the inclusion of fly ash and glass powder presented a reduction in compressive strength compared to PC. However, T1 presented attributes such as lower capillary absorption, which indicates that it is a mixture with low porosity; Therefore, it will be a mixture resistant to substances such as sulfates; which will be evidenced by a longer service life in the structures built with this type of mixture.
