Optimización mecánica de muestras de Bloques de Tierra Comprimida (BTC): presión y estabilización.

Abstract

The impacts generated by the construction sector are one of the most recurrent affectations mentioned in the literature, this derived from the resources used either in the use of raw materials, as well as in industrial processes. In this sense, Technologies through the implementation and use of the Soil can represent alternatives applicable to this sector, which make it possible to reduce these impacts, opening an area of study for this type of technology and reducing the negative impact on the environment. The foregoing has increased interest in materials available in the region that have adequate performance and that help improve the mechanical performance of the walls. The objective of this research is to know and compare the mechanical behavior of Compressed Earth Blocks (CEB) by preparing samples with earth from the northern region of Mexico, specifically from Torreón, Coahuila, studied using an experimental method analyzing different pressures, to determine if the increase or decrease in, is influences your physical-mechanical behavior. Plant and mineral stabilizers were used to analyze the behavioral variations between them and identify the most suitable material to stabilize the studied sample. All the above in accordance with compression tests carried out in a controlled environment, respecting current regulations. The results show that, at higher pressure, greater resistance is obtained, lime was the stabilizing element with which better results were obtained in mechanical tests, however, vermiculite had a similar mechanical behavior and the pieces were 20 % lighter than those made with lime, which opens the possibility of continuing to analyze and study this material seeking to improve its mechanical behavior to make way for its implementation in buildings.
