Physical, Mechanical, and Durability Properties of Compressed Earth Blocks Filled by Juncus Plant Fibers

This paper studies the influence of incorporating Juncus fibers into compressed earth blocks (CEBs). CEB composites were manufactured with earth filled by Juncus fibers reinforcement (0 to 0.8% by weight), and compressed at 10 MPa with a compaction loading press. After 28 days of drying, the CEBs underwent diverse experimental tests to evaluate their physical, mechanical, and durability properties. The findings indicated that incorporating fibers led to a diminution in unit weight, ultrasonic pulse velocity, and dry compressive strength. Despite the drop in mechanical strength, CEBs with higher fiber content (0.4%) demonstrated satisfactory abrasion resistance, which could play a crucial role in areas prone to extreme weather events. According to this experimental investigation, this material has the potential as a promising composite for building materials and reduces the need for chemical stabilizers, which is considered a major contributor to greenhouse gas emissions in the construction industry. The results have implications for affordable housing solutions and offer insightful information about sustainable building materials.
