From agave to earthen architecture. Use of natural fibers from agro-industrial waste in the manufacture of biocomposite adobe

Abstract

Adobe is resistant to sudden temperature changes and fire, acting as an effective thermal and acoustic barrier in construction. This article investigates the thermal, resistance, compression, plasticity and absorption properties of biocomposite adobe, proposing that the combination of adobe with agave bagasse significantly improves its efficiency compared to blocks composed of zacate, agave fibers and soil. This study was conducted in a mezcal and traditional adobe producing area in the State of Mexico, in line with the principles of circular economy. Results indicate that adobe enriched with agave bagasse presents several improvements in its physical and mechanical properties, which reduces its environmental impact. This research highlights the importance of adobe as a fundamental element in the revaluation of earthen architecture, contributing to the promotion of heritage identity.
