【摘要】 利用秸秆制备建筑材料可解决秸秆综合利用的问题,减少环境危害和能源消耗,助力"碳中和"。本文从原料、工艺、应用领域、性能参数等方面对秸秆建材的优势与劣势进行了梳理与总结,分析秸秆建材目前存在的主要问题,并提出未来的研究方向。当前秸秆建筑材料的制备主要以秸秆形态掺入和以秸秆制备的生物炭形态掺入2种方式为主,结果表明添加秸秆可提高混凝土建材力学性能、改良湿热性能,但缺乏标准和产业化困难仍限制了其发展。未来在秸秆预处理工艺创新、纤维与水泥基质结合机理、生物炭补偿秸秆建材在抗压强度和抗碳化能力、胶粘剂、优化无胶胶合工艺等方面的研究还需要继续深入。更多还原

【Abstract】 Using straw to prepare building materials can solve the problem of comprehensive utilization of straw, reduce environmental harm and energy consumption, and help " carbon-neutral". In this paper, the advantages and disadvantages of straw building materials are summarized from the aspects of raw materials, technology, application fields, performance parameters,etc., the main problems existing in the straw building materials are analyzed, and future research directions are proposed. At present, straw building materials are mainly prepared by straw form incorporation and straw biochar form incorporation. The experimental results show that adding straw can improve the mechanical properties of concrete building materials and improve the humidity and heat properties, but the lack of standards and industrialization difficulties still limit the development of straw building materials. In the future, further research is needed in the fields of straw pretreatment technology innovation, fiber and cement matrix bonding mechanism research, biochar compensation straw building materials in compressive strength and carbonization resistance research, adhesive research, optimization of glue-free bonding technology and other aspects.更多还原
