Abstract
En el proyecto de investigación se han comparado las propiedades mecánicas de los morteros
hidráulicos y los morteros poliméricos utilizados en aplicaciones de mampostería, analizando
asimismo las características y componentes del mortero polimérico Brickaffix, así como las
normativas nacionales e internacionales pertinentes para la comparación.
Para determinar las características físicas y mecánicas de ambos tipos de mortero se han realizado
ensayos de laboratorio según las Normas ASTM, para cuantificar y cualificar las propiedades
mecánicas del mortero polimérico Brickaffix y del mortero hidráulico, con dosificaciones 1:3, 1:4 y
1:5.
Se han evaluado propiedades como la resistencia a la compresión, el porcentaje de flujo, el
porcentaje de absorción y el peso unitario, así como las ventajas y desventajas del mortero
hidráulico y el mortero polimérico Brickaffix en términos de resistencia y facilidad de uso.
Se ha determinado que el mortero polimérico Brickaffix es más resistente a la compresión que su
contraparte, absorbe menos agua, es más adherente a los elementos de mampostería, tiene la
misma densidad y su trabajabilidad es similar a la del mortero hidráulico convencional usado en
obras, sin embargo, obtuvo una menor resistencia a la flexión, lo que sugiere que podría no ser la
mejor opción en aplicaciones donde se requiera una alta resistencia a la flexión.
En conclusión, el mortero polimérico Brickaffix es una opción viable para aplicaciones donde se
requiere alta resistencia a la compresión y baja absorción de agua, aunque no es la mejor opción
para aplicaciones que requieren alta resistencia a la flexión.
In the research project, the mechanical properties of hydraulic mortars and polymeric mortars used in masonry applications were compared, analyzing the characteristics and components of the polymeric mortar Brickaffix, as well as the relevant national and international standards for comparison. Laboratory tests were conducted according to ASTM Standards to determine the physical and mechanical characteristics of both types of mortar, to quantify and qualify the mechanical properties of the polymeric mortar Brickaffix and the hydraulic mortar, with dosages of 1:3, 1:4, and 1:5. Properties such as compressive strength, flow percentage, absorption percentage, and unit weight were evaluated, as well as the advantages and disadvantages of hydraulic mortar and polymeric mortar Brickaffix in terms of strength and ease of use. It was determined that the polymeric mortar Brickaffix is more resistant to compression than its counterpart, absorbs less water, is more adherent to masonry elements, has the same density, and its workability is like that of conventional hydraulic mortar used in construction. However, it showed lower flexural strength, suggesting that it may not be the best option for applications where high flexural strength is required. In conclusion, the polymeric mortar Brickaffix is a viable option for applications where high compressive strength and low water absorption are required, although it is not the best option for applications that require high flexural strength.
