Enhancement of Mechanical and Thermal Qualities in Compressed Blocks Reinforced With Coconut Fibers

We explore the variation of bulk density of the compressed earth blocks (CEBs) reinforced with coconut fibers as a way to reduce overall weight, modulate porosity, and ultimately influence thermal conductivity. The main idea is to investigate, through experimentation, the influence of compaction pressure process applied to CEBs bulk density and subsequently discerning its repercussions on thermal performance, specifically thermal conductivity, and mechanical properties, including compressive strength. In accordance with the results obtained, it is observed that the bulk density exerts a substantial impact on the CEBs thermal and mechanical behavior. Indeed, thermal conductivity presents a concordant reaction with bulk density, thus, indicating that a decrease in the latter is associated with a significant reduction in thermal conductivity. The linear characterization of thermal properties in relation to bulk density delineates the observed variation. However, it is imperative that the bulk density does not cross a minimum threshold, so that the CEBs can maintain the cohesion and the compressive strength.
