          Abstract

          Resumen En la búsqueda de materiales para construcción sostenible, los ladrillos de adobe juegan un papel importante por generar menor impacto que otros materiales. Hay diversas investigaciones y desarrollos para mejorar sus características como resistencia y durabilidad, entre otras. En el presente trabajo, en una primera fase, se estudiaron las propiedades mecánicas de una mezcla de ladrillo en tierra, arcilla, arena y fibras vegetales secas. En la mezcla seleccionada se evaluó la germinación de material vegetal (pasto) en su superficie y sus propiedades mecánicas una vez que el material se desarrolló. Como resultado, se encontró que la mezcla de ladrillo seleccionada presenta menor resistencia a la compresión que otros ladrillos de adobe, pero la fibra incorporada permite que sea más estable. Además, la combinación de materiales posibilitó una menor densidad y mayor absorción de agua, lo que facilitó el desarrollo de material vegetal en su superficie y que se ganara estabilidad al generarse una red entre las raíces. Tales hallazgos permiten concluir que es posible su aplicación en muros verdes con alturas menores de cuatro metros.

          Abstract In the search for materials for sustainable construction, adobe bricks play an important role in generating less negative environmental impact than other materials. Proof of this is the large number of research projects focused on improving the properties of the bricks such as resistance or durability. The present work studied the mechanical properties of bricks composed by a mixture of soil, clay, sand and dried vegetable fibers. On this selected mixture, the germination of plants on the surface of the brick and its mechanical properties were studied. We found that the selected mixture has less resistance to compression than other adobe bricks, but on the other hand the vegetable fiber confers more stability on them. Additionally, the combination of the materials conduces to obtain less dense bricks, with higher absorption of water, which facilitated the growth of plants on the surface, gaining more stability due to the network of plant roots. These findings allow us to conclude that it is possible the application of these bricks in the construction of medium height green walls.
