“…Its application greatly compensates for the shortage of skilled laborers, resources, and construction efficiency [104]. The application of large-scale AM with cementbased material ink in civil engineering is also known as 3D printing [103,105,106]. A concise definition of 3D printing technology in construction is "transforming an imagination of a facility, in whole or in part, depicted through a computer model, into a real facility (bridges, highways, buildings, etc.…”

Design is a goal-oriented planning activity for creating products, processes, and systems with desired functions through specifications. It is a decision-making exploration: the design outcome may vary greatly depending on the designer’s knowledge and philosophy. Integrated design is one type of design philosophy that takes an interdisciplinary and holistic approach. In civil engineering, structural design is such an activity for creating buildings and infrastructures. Recently, structural design in many countries has emphasized a performance-based philosophy that simultaneously considers a structure’s safety, durability, serviceability, and sustainability. Consequently, integrated design in civil engineering has become more popular, useful, and important. Material-oriented integrated design and construction of structures (MIDCS) combine materials engineering and structural engineering in the design stage: it fully utilizes the strengths of materials by selecting the most suitable structural forms and construction methodologies. This paper will explore real-world examples of MIDCS, including the realization of MIDCS in timber seismic-resistant structures, masonry arch structures, long-span steel bridges, prefabricated/on-site extruded light-weight steel structures, fiber-reinforced cementitious composites structures, and fiber-reinforced polymer bridge decks. Additionally, advanced material design methods such as bioinspired design and structure construction technology of additive manufacturing are briefly reviewed and discussed to demonstrate how MIDCS can combine materials and structures. A unified strength-durability design theory is also introduced, which is a human-centric, interdisciplinary, and holistic approach to the description and development of any civil infrastructure and includes all processes directly involved in the life cycle of the infrastructure. Finally, this paper lays out future research directions for further development in the field.

“…Another study confirmed the weak thixotropic behavior of the two-part AAMs (using metakaolin and sodium silicate solution) compared to OPC due to the absence of colloidal interaction (Favier et al 2014). Nevertheless, limited studies implemented the hysteresis test and stress decay method to observe the thixotropic behavior of two-part AAMs (Panda et al 2018;Kondepudi and Subramaniam 2019) and one-part AAMs (Guo et al 2020), while other studies (Panda et al 2019;Bong et al 2021;Muthukrishnan et al 2021) reported the viscosity recovery behavior besides the static yield stress of both one-part and two-part AAMs for 3D printing purposes. effect of activator properties and water content on the structural build-up behavior of alkali-activated fly ash/slag pastes.…”

“…Several studies focused on the rheological behavior of the two-part AAMs, including pastes (made from fly ash (Rashad 2014;Palacios et al 2019;Rifaai et al 2019), slag (Rashad 2013;Puertas et al 2014;Palacios et al 2021), metakaolin (Poulesquen et al 2011;Favier et al 2014), or their blends (G et al 2019;Guo et al 2020), mortars (Alonso et al 2017), and concrete (Puertas et al 2018). In contrast, limited studies focused on one-part AAMs (Luukkonen et al 2019;Li et al 2020;Lu et al 2021;Alrefaei and Dai 2022).…”

Compared with conventional two-part alkali-activated materials (AAMs), one-part AAMs have several advantages, especially the simple production using only water similar to ordinary Portland cement. However, one-part AAMs are much less researched, especially in terms of rheology. Understanding the rheological behavior of such binders is a crucial step for their production, placement, and application in the construction industry. This paper studies the rheological properties of one-part AAMs through evaluating the dynamic yield stress, static yield stress, and thixotropic index. The effects of solid activator content, besides the effect of two types of fly ash (containing different amounts of carbonaceous impurities) with varying contents, are explored. The possible mechanisms are also discussed.

“…To accurately predict the effect of different quartz sand and carbon fiber contents on the initial viscosity of HIT-LRS-1 GP ink and its minimum extrusion stress (minimum τ 0 ), the H-B model [49] was selected to fit the stress-strain curves of HIT-LRS-1 GP, 20QS@HIT-LRS-1 GP, and 1C sf /20QS@HIT-LRS-1 GP inks in Fig. 5(c).…”

Over time, natural materials have evolved to be lightweight, high-strength, tough, and damage-tolerant due to their unique biological structures. Therefore, combining biological inspiration and structural design would provide traditional materials with a broader range of performance and applications. Here, the application of an ink-based three-dimensional (3D) printing strategy to the structural design of a Lunar regolith simulant-based geopolymer (HIT-LRS-1 GP) was first reported, and high-precision carbon fiber/quartz sand-reinforced biomimetic patterns inspired by the cellular sandwich structure of plant stems were fabricated. This study demonstrated how different cellular sandwich structures can balance the structure-property relationship and how to achieve unprecedented damage tolerance for a geopolymer composite. The results presented that components based on these biomimetic architectures exhibited stable non-catastrophic fracture characteristics regardless of the compression direction, and each structure possessed effective damage tolerance and anisotropy of mechanical properties. The results showed that the compressive strengths of honeycomb sandwich patterns, triangular sandwich patterns, wave sandwich patterns, and rectangular sandwich patterns in the Y-axis (Z-axis) direction were 15.
