Mechanical and durability properties of hybrid natural fibre reinforced roadbed foamed concrete

Challenges in Foamed Concrete: Exploring Alternative and Sustainable Materials – A Comprehensive Review

“…The incorporation of fibers into foamed concrete has proven to be a significant factor in enhancing mechanical properties, leading to improvements in flexural behavior and compressive strength (43,(61)(62)(63)(64)(65). Beyond these structural benefits, the inclusion of fibers has also been shown to enhance the overall stability of the material.…”

“…To optimize the thermal performance of foamed concrete, studies have unveiled that the introduction of voids or air cells plays a pivotal role in enhancing its insulation behavior. The stability of preform foam, coupled with the deliberate incorporation of microbubbles into the concrete matrix, significantly contributes to this improved thermal efficiency (14,40,61,64,107,113). However, it's crucial to note that while these advancements positively impact insulation, they also exert influences on both compressive strength and elastic modulus, underscoring the need for a balanced consideration of multiple factors in the pursuit of energyefficient construction solutions (60,104,115,116).…”

“…While acknowledging that its durability may be comparatively reduced when juxtaposed with Portland cement, careful considerations throughout its life cycle become imperative to ensure longevity. Nevertheless, foamed concrete showcases notable strength in diverse aspects, exhibiting resilience against challenges such as resistance to freeze-thaw cycles, elevated temperatures, carbonation, and more (27,47,49,64,117,118). The multifaceted durability profile of foamed concrete underscores its potential as a resilient and reliable construction material, particularly when tailored to address specific environmental conditions and project requirements.…”
