摘      要：Biochar is a waste-derived material that can sequester carbon at a large *** development of low-carbon and sustainable biochar-enhanced construction materials has attracted extensive ***,having a porous nature and highly functionalised surface,can provide nucleation sites for chemical reactions and exhibit compatibility with cement,asphalt,and polymer *** study critically reviewed the state-of-the-art biochar-enhanced construction materials,including biochar-cement composites,biochar-asphalt composites,biochar-plastic composites,*** efficacies and mechanisms of biochar as construction materials were articulated to improve their functional *** critical review highlighted the roles of biochar in cement hydration,surface functional groups of engineered biochar for promoting chemical reactions,and value-added merits of biochar-enhanced construction materials(such as humidity regulation,thermal insulation,noise reduction,air/water purification,electromagnetic shielding,and self-sensing).The major properties of biochar are correlated to the features and functionalities of biochar-enhanced construction *** advances in our understanding of biochar’s roles in various composites can foster the next-generation design of carbon-neutral construction materials.
