Abstract
AbstractFluid catalytic cracking (FCC) ash is a common industrial waste in the crude oil refinery process. In this study, raw FCC ash was incorporated to develop sustainable MgO/FCC ash blends for 3D printing on vertical surfaces. Rheological and tack behaviors of MgO/FCC ash blends were systematically studied, followed by the assessment of mechanical property and hydration products. On this basis, the suitable mixture for 3D printing on the vertical surfaces was determined, and its feasibility was verified with lab-scale 3D printing. Finally, the environmental impact of the developed mixture was estimated through batch leaching and composition tests. This study provides an alternative method to upcycle FCC ash as an ingredient for 3D concrete printing, which brings benefits to both the construction and oil refinery industries. Besides, the rheological, tack, and hydration investigations of the MgO/FCC ash blends guide the future design of similar mixtures with upcycled wastes.Keywords: fluid catalytic cracking (FCC)3D concrete printingsustainabilityrheologytackiness Disclosure statementThe authors declare no conflict of interest.Additional informationFundingThis research is supported by the National Research Foundation, Prime Minister’s Office, Singapore under its Medium-Sized Centre funding scheme, CES_SDC Pte Ltd, and Chip Eng Seng Corporation Ltd.

摘要催化裂化灰分是原油炼制过程中常见的工业废弃物。在本研究中,将FCC粗灰掺入其中,开发可持续的MgO/FCC灰混合物,用于垂直表面的3D打印。系统研究了MgO/FCC灰共混物的流变和黏附行为,并对其力学性能和水化产物进行了评价。在此基础上,确定了适合垂直表面3D打印的混合材料,并通过实验室规模的3D打印验证了其可行性。最后,通过批量浸出和成分测试,对开发的混合物的环境影响进行了评估。本研究提供了一种将FCC灰分升级为3D混凝土打印原料的替代方法,这对建筑和炼油行业都有好处。此外,MgO/FCC灰共混物的流变学、粘性和水化研究为未来设计类似的再生废物混合物提供了指导。关键词:催化裂化(FCC)3D混凝土打印可持续性流变黏性披露声明作者声明无利益冲突本研究由新加坡国家研究基金会、新加坡总理办公室的中型中心资助计划、CES_SDC Pte Ltd和Chip Eng Seng Corporation Ltd支持。作者要感谢王翔宇和王立宁在3D打印实验中的帮助。作者还要感谢新加坡ECO特殊废物管理有限公司为本研究提供FCC灰。
期刊介绍:
The Journal of Sustainable Cement-Based Materials aims to publish theoretical and applied researches on materials, products and structures that incorporate cement. The journal is a forum for discussion of research on manufacture, hydration and performance of cement-based materials; novel experimental techniques; the latest analytical and modelling methods; the examination and the diagnosis of real cement and concrete structures; and the potential for improved cement-based materials. The journal welcomes original research papers, major reviews, rapid communications and selected conference papers. The Journal of Sustainable Cement-Based Materials covers a wide range of topics within its subject category, including but are not limited to: • raw materials and manufacture of cement • mixing, rheology and hydration • admixtures • structural characteristics and performance of cement-based materials • characterisation techniques and modeling • use of fibre in cement based-materials • degradation and repair of cement-based materials • novel testing techniques and applications • waste management
