“…After three months of soaking, the specie's sugar content is reduced by 50-60%. A durability test revealed that treated bamboo culms deteriorated far more slowly than untreated ones [57]. Additionally, during durability testing, bamboo samples that had been treated for a month showed a minor percentage biomass loss.…”

“…Results indicated that the off-axis compressive performance of CLBT specimens varied smoothly with the increase of off-axis angle compared with gluelaminated timber specimens. Li et al [57] extended their study to investigate the in-plane compressive performance of CLBT wall panels. The compressive angle of the specimens was varied from 0 to 90 degrees.…”

Bamboo is a natural biodegradable material used as a strength-bearing material that operates for system works, formwork supporting stands, structural members in low-rise houses, props, framing, bridges, laminated flooring, facades, walls, roofs, and trusses. Over recent years, there has been an increased demand for bamboo, considering sustainable construction practices. Exploring bamboo’s physical and mechanical behaviour is essential to develop innovative construction methods and design guidelines. Therefore, this paper aims to review the studies on bamboo culms’ material properties and physical behaviour, considering the load-bearing capacity and structural adequacy. This study summarises the physical and mechanical properties of a wide array of bamboo species grown worldwide. Mechanical properties such as compressive, tensile, flexural, shear, and bucking strengths are explored, highlighting the key findings in previous experimental works. Results have indicated a significant variability in bamboo’s material and mechanical properties considering the growth conditions, location along a culm, geometric imperfections and environmental conditions. In addition to material and mechanical properties, structural bamboo connections, engineered bamboo products, and preservative treatment of bamboo are also investigated. The construction industry can utilise the summary of the findings of this study to develop design guidelines for sustainable bamboo construction. Overall, this paper presents an overview of structural capability and drawbacks for future research and development using bamboo in modern construction.

“…In this framework, the importance of CLT panels has become so relevant that several studies [23][24][25][26][27], have concerned panels made with different wood species compared to fir and spruce, which are currently the most used species for CLT industrial productions.…”

Establishing short supply chains for timber has become important especially in Italy, which is an historically wood-importer country. Timber is an environmentally friendly construction material and a potential mean to reduce carbon footprint produced every year by the building sector. In addition to its sustainability benefits, reversible strengthening interventions can be attained for existing structures. As such, timber can be efficiently used to preserve and protect historical buildings which are, due to architectural and aesthetic values, fundamental components of the Italian cultural heritage. In this study, the use and potential of novel cross-laminated (X-Lam or CLT) timber panels made of Italian hardwood (i.e., beech) for strengthening of existing timber floors is investigated. A quantitative comparison between the mechanical performances of the proposed wood-based product and common retrofitting techniques, such as double-crossed timber planks and reinforced concrete slabs, is carried out in terms of bending stiffness (which is evaluated according to Eurocode 5), influence of weight and reversibility of intervention. It is shown that CLT panels represent a good compromise/alternative for the realisation of reversible and sustainable reinforcing interventions, with rather well promising performances.

To promote resource reuse and the green, low-carbon transformation of the construction industry, this study uses recycled aggregate from crushed waste concrete and natural bamboo fibers to formulate bamboo fiber-reinforced recycled-aggregate concrete. This study investigates the effects of natural bamboo fiber (NBF) content, NBF length, and the water-to-cement ratio on the performance of concrete through an orthogonal experiment to determine the optimal mixing proportions of NBF-reinforced concrete. Additionally, recycled aggregate completely replaced natural aggregate. The mechanism by which NBF influences concrete was also analyzed. The results demonstrate that the NBF-reinforced specimens exhibited good integrity during compression failure, with NBFs effectively tying the concrete together. The optimized parameters for NBF-reinforced concrete were an NBF length of 20 mm, an NBF content of 0.4v%, and a water-to-cement ratio of 0.55. Almost no flaky Ca(OH)2 crystals were observed in the NBF-hardened cement–paste transition zone, indicating effective bonding at the interface.
