“…Otherwise, the reinforcement of the adobe increased the ductility index except for the D3 mixture. The improvement of the ductility is consistent with the finding of [19]. 10 represents the evolution of bending strength (MPa) as a function of the mass ratio of fiber mass.…”

“…In the first part of the curve defining the elastic domain, the modulus of elasticity E, or Young's modulus, defined as the slope of the curve stress-strain, makes it possible to set up a correspondence between the variation of applied stress and the variation in deformation observed. Otherwise, to study the ductility of the material, an index I "adapted to the earth and earth fiber material was developed by [19]. The index I is defined as:…”

“…The addition of synthetic fibers in concrete results in a new composite material that exhibits different cracking performance and overall behavior than common concrete. A notable influence of the synthetic fibers on improving the post-peak compressive behavior was observed, which indicates the ability of fiber-reinforced concrete to provide increased ductility [21,22]. Also, according to the main finding of the paper by Imanzadeh et al, is that increasing the silt-to-binder ratio improves the material's ductility, while the inclusion of flax fibers significantly aids in maintaining cohesion and ductility after the peak stress point [23].…”

Fiber-reinforced mycelium (FRM) composites offer an innovative and sustainable approach to construction materials for architectural structures. Mycelium, the root structure of fungi, can be combined with various natural fibers (NF) to create a strong and lightweight material with environmental benefits. Incorporating NF like hemp, jute, or bamboo into the mycelium matrix enhances mechanical properties. This combination results in a composite that boasts enhanced strength, flexibility, and durability. Natural FRM composites offer sustainability through the utilization of agricultural waste, reducing the carbon footprint compared to conventional construction materials. Additionally, the lightweight yet strong nature of the resulting material makes it versatile for various construction applications, while its inherent insulation properties contribute to improved energy efficiency in buildings. Developing and adopting natural FRM composites showcase a promising step towards sustainable and eco-friendly construction materials. Ongoing research and collaboration between scientists, engineers, and the construction industry will likely lead to further improvements and expanded applications. This article provides a comprehensive analysis of the current research and applications of natural FRM composite for innovative and sustainable construction materials. Additionally, the paper reviews the mechanical properties and potential impacts of these natural FRM composites in the context of sustainable architectural construction practices. Recently, the relevance of mycelium-based materials has extended beyond their original fields of microbiology and mycology to architecture.

This study assesses the usability of natural materials available in Australia’s remote communities for making fibre-reinforced mudbricks. The present construction cost for housing in remote areas is too high to maintain the level of housing required for the remote Australian population. As this includes mostly First Nations communities, more culturally appropriate housing materials and construction methods are being considered. This study looks at mudbricks made from laterite soil reinforced by spinifex fibre, both available in abundance in remote communities. Hence, this material is more acceptable to communities as it is more sustainable, and the construction methods are more suited for First Nations engagement. Various mixes were tested for compressive strength and erosion resistance. Results suggest that spinifex can significantly improve compressive strength and reduce erosion effects; however, spinifex showed adverse effects at the early stage of the spray test. The results satisfy the minimum strength and erosion resistance requirements for construction and suggest that spinifex-reinforced mudbricks could potentially be considered as an alternative material in remote housing.
