Biochar foam concrete with efficient carbon sequestration performance
The invention discloses charcoal foam concrete with efficient carbon sequestration performance, and belongs to the technical field of carbon sequestration materials. A foam concrete material is adopted to load biochar, and the biochar foam concrete material is obtained. The biochar foam concrete material disclosed by the invention is uniform in pore structure and good in stability, can show an excellent carbon sequestration effect by virtue of a synergistic carbon sequestration effect in three aspects of characteristics of biochar, CO2 adsorption characteristic and carbonization reaction characteristic of a cement-based material, and has a good demonstration effect of a low-carbon cement-based material. According to actual experimental results, when the biochar substitution rate is 6% and 7.5%, the CO2 emission reduction rates of the material in the whole life cycle can exceed 50% and 60% respectively; according to theoretical calculation, when the biochar substitution rate reaches 12%, the CO2 emission reduction rate can reach 100%.
本发明公开了一种具有高效固碳性能的生物炭泡沫混凝土，属于碳封存材料技术领域。采用泡沫混凝土材料对生物炭进行负载，得到生物炭泡沫混凝土材料。本发明的生物炭泡沫混凝土材料其孔隙结构均匀、稳定性好，凭借生物炭自身的特性、对CO2的吸附特性以及水泥基材料的碳化反应特性三方面的协同固碳作用，能够表现出优异的固碳效果，有良好的低碳水泥基材料示范效果。根据实际实验结果，在生物炭取代率为6％和7.5％时，该材料全生命周期的CO2减排率可分别超过50％和60％；根据理论计算，当生物炭取代率达到12％时，CO2减排率可达到100％。
