| description | To address the issue of significant waste generated from bamboo scraps and the low added value of associated products, this study explored their transformation into high-value resources. Chitosan hydrochloride (CH) was used as a modifier, and bamboo scraps/magnesium oxychloride cement formed the composite matrix. Hydrogen peroxide (H2O2) served as the chemical foaming agent to produce a lightweight, green building material. The study utilized CH in weak alkaline environments and harnessed its effective film-forming properties to address key issues associated with plant-based magnesium oxychloride materials. These issues included poor water resistance, weak interfacial compatibility, uneven material mixing, and susceptibility to warping and deformation. The modified bamboo scraps/magnesium chloride cement composite exhibited improved uniformity, fluidity, toughness, and mechanical strength. Consequently, the composite achieved a maximum compressive strength of 5.0 MPa, a bending stress of 0.65 kN, and a tensile stress of 13.1 kN. The incorporation of CH led to a 36.5 % increase in the toughness of the composite material compared with the blank group. After soaking in water for 3 days, the compressive strength of the modified composite increased by up to 120 % compared with the unmodified group. This study provides an effective approach for utilizing bamboo resources, enhancing the forestry industry, supporting rural economic development, and promoting environmental sustainability and pollution reduction. Additionally, the research introduces new pathways for developing eco-friendly building materials. |
