Abstract

As global CO2 concentrations rise, there is a pressing need for sustainable alternatives in the construction sector as many countries are striving to attain net carbon neutrality. Integrating carbon capture and sequestration (CCS) technologies directly into 3D concrete printing offer a promising solution to reduce the carbon footprint in the construction sector. This paper investigates a novel printing technique involving the purging of pressurised CO2 gas was demonstrated and the various process parameters were evaluated for its effectiveness in promoting carbon sequestration. Results show that the carbon-sequestrated sample has a 15% increase in carbon uptake as compared to the control sample. The method can be complementary to existing sequestration technologies, facilitating large-scale carbon sequestration without chamber size limitations. Nevertheless, further research and development are necessary to optimise the various printing parameters and achieve a more balanced and efficient integration of carbon capture and sequestration technologies with 3DCP.

通过3D混凝土打印探索碳封存潜力

随着全球二氧化碳浓度的上升，建筑行业迫切需要可持续的替代品，因为许多国家都在努力实现净碳中和。将碳捕获和封存(CCS)技术直接集成到3D混凝土打印中，为减少建筑行业的碳足迹提供了一个很有前途的解决方案。本文研究了一种新型的印刷技术，包括加压二氧化碳气体的净化，并评估了各种工艺参数，以促进碳封存的有效性。结果表明，固碳样品的碳吸收量比对照样品增加了15%。该方法可以作为现有固碳技术的补充，促进大规模的碳固碳，而不受碳室尺寸的限制。然而，需要进一步的研究和开发，以优化各种打印参数，实现碳捕获和封存技术与3DCP更平衡、更有效的整合。
