近年来,由于3D混凝土打印技术的经济和科学优势,全球对其越来越感兴趣。泡沫混凝土的应用,以其卓越的隔热和隔音性能而闻名,不仅具有经济吸引力,而且与可持续发展原则无缝衔接。本研究探讨了建筑中与3D打印技术相关的各种解决方案,讨论设计,生产,泡沫混凝土混合物的性能。3D打印的集成和整个过程自动化的潜力为提高生产率和降低建筑成本提供了机会。此外,泡沫混凝土的使用具有良好的保温性能,将减少混凝土以外的材料的使用(例如,矿棉,立面网格,和聚苯乙烯),大大促进建筑物拆除过程中的回收过程。这个,反过来,将导致不可再生自然资源的保护和二氧化碳排放量的减少。尽管结果很有希望,有有限的研究集中在3D打印与泡沫材料,尽管对现有文献的调查表明,在3D打印领域中,与加气混凝土的利用有关的努力明显缺乏,特别是地质聚合物复合材料(GP)和混合地质聚合物复合材料(HGP)。随后的论述中描述的结果是对常规使用的材料而不是增材制造变体的证明。因此,这项工作旨在系统地回顾与使用3D打印技术生产泡沫混凝土相关的现有实践和技术。该分析还有助于建立基础框架,并为未来针对加气混凝土3D打印的努力提供了初步基础。文献分析的结果证明了继续研究这一主题的必要性,特别是在考虑大规模工业实施的潜力时。本文提供了有关泡沫混凝土混合物3D打印技术发展的全面知识。通过巩固和分析不同研究的发现,这篇文章提供了对进步的见解,挑战,以及泡沫混凝土在增材制造过程中的潜在应用。这个,反过来,使用泡沫混凝土作为通用和可持续的建筑材料,有助于对3D打印技术的整体理解和进步。从分析中获得的令人鼓舞的结果进一步强调了继续探索3D打印的必要性。特别是着眼于其工业规模的实施。
Recent years have witnessed a growing global interest in 3D concrete printing technology due to its economic and scientific advantages. The application of foamed concrete, renowned for its exceptional thermal and acoustic insulation properties, not only holds economic attractiveness but also aligns seamlessly with the principles of sustainable development. This study explores various solutions related to 3D printing technology in construction, discussing the design, production, and properties of foamed concrete mixtures. The integration of 3D printing and the potential for automating the entire process offers opportunities to boost productivity and reduce construction costs. Furthermore, the utilization of foamed concrete with its commendable insulation properties will enable a reduction in the usage of materials other than concrete (e.g., mineral wool, facade mesh, and polystyrene), significantly facilitating the recycling process during building demolition. This, in turn, will lead to the preservation of nonrenewable natural resources and a decrease in CO2 emissions. Despite the promising results, there have been limited studies focusing on 3D printing with foamed materials, whereas a survey of the existing body of literature indicates a notable absence of endeavors pertaining to the utilization of aerated concrete within the realm of 3D printing, especially geopolymer composites (GP) and hybrid geopolymer composites (HGP). The outcomes delineated in the ensuing discourse are demonstrative for conventionally used materials rather than the additive manufacturing variant. Hence, this work aims to systematically
review existing practices and techniques related to producing foamed concrete with 3D printing technology. This analysis also contributes to the establishment of a foundational framework and furnishes a preliminary basis upon which future endeavors aimed at the 3D printing of aerated concrete can be embarked. The findings from the literature analysis justify the desirability of continuing research on this topic, particularly when considering the potential for large-scale industrial implementation. This article provides a comprehensive state of the knowledge on the development of 3D printing techniques for foamed concrete mixtures. By consolidating and analyzing findings from different studies, this article offers insights into the advancements, challenges, and potential applications of foamed concrete in additive manufacturing processes. This, in turn, contributes to the overall understanding and advancement of 3D printing technologies using foamed concrete as a versatile and sustainable construction material. The encouraging results obtained from the analysis further underscore the need for the continued exploration of 3D printing, especially with an eye towards its industrial-scale implementation.
