建筑建材领域"以竹代塑"工程材料研究现状与发展趋势OA北大核心CSTPCD

As the global attention to sustainable development deepens,the construction industry faces growing environmental challenges posed by traditional building materials.Plastic,while widely used in construction for its favorable physical properties,has a significant environmental impact due to its non-degradability.Bamboo,as a rapid renewable resource,possesses excellent mechanical properties and environmentally friendly characteristics.Bamboo-based engineering materials,promoted as"bamboo as a substitute for plastic",are gradually becoming a research and application hotspot,demonstrating promising environmental performance and economic value.In recent years,researchers have continually explored new technologies and methods for manufacturing bamboo-based engineering materials,resulting in a series of novel bamboo-based building materials characterized by"bamboo as a substitute for plastic".With ongoing technological advancements,bamboo engineering materials have demonstrated promising prospects in practical applications and have been initially used in fields such as ecological buildings and green communities.This study focused on the advantages and potential of"bamboo as a substitute for plastic"engineering materials as alternatives to traditional plastics,reviewed the current research status of"bamboo as a substitute for plastic"engineering materials in the construction and building materials,including material classification,reparation processes,modification techniques and practical applications.It systematically analyzed the necessity of mainstream"bamboo as a substitute for plastic"engineering materials in the construction field,explored the preparation processes and technological improvements for"bamboo as a substitute for plastic"engineering materials,and compared the current state of related technologies domestically and internationally.Furthermore,it identified the main issues hindering the promotion of"bamboo as a substitute for plastic"engineering materials and offering suggestions for further development.This research indicated that"bamboo as a substitute for plastic"engineering materials exhibited excellent performance in strength and durability,effectively replacing traditional plastic building materials,while also reducing carbon emissions in the construction industry and promoting green building development.The bamboo engineering materials have been successfully applied in ecological buildings and other areas.However,existing standards and regulations remain insufficient,and market promotion is still lacking.This study provided a systematic review of the research status of"bamboo as a substitute for plastic"engineering materials,aiming to offer theoretical support for the promotion of bamboo in the field of construction and building materials.In the future,considering economic,environmental and social benefits,promoting the development of technical standards and quality control systems for bamboo-based building materials,as well as their standardized application and market promotion,will be the key to advance the wider use of bamboo as a substitute for plastic materials.With continued research and collaboration,bamboo-based engineering materials as a substitute for plastic will play an increasingly important role in the sustainable development of the construction and building materials industry.
