The realities of additively manufactured concrete structures in practice

Structural validation of geothermal water basins constructed with durability enhanced ultra high performance fiber reinforced concrete (Ultra High Durability Concrete)

“…On the other hand, in order to bring UHPC to an as broad as possible market, its use has not to be foreseen just for mere incremental upgrading of existing structural concepts, and then confined to reduction of reinforcement cover and element thicknesses, but as a driver to realize innovative structure concepts. This also in synergy with tailored construction technologies including prefabrication and additive manufacturing, whose implementation would not be otherwise feasible [16][17][18][19][20].…”

Thermal Optimization of Additively Manufactured Lightweight Concrete Wall Elements with Internal Cellular Structure through Simulations and Measurements

“…Concrete extrusion describes an AM technology where concrete strands are deposited layer by layer in order to build a free-form concrete element. Walls for residential buildings were already extruded with this technology [10]. By combining this AM technology with lightweight concrete [11], and optimizing its inner structure, monolithic building elements are possible, optimizing both structural and building physics performance [12].…”

Characterizing the Bond Properties of Automatically Placed Helical Reinforcement in 3d Printed Concrete

“…One of these technologies is 3D concrete printing (3DCP), where concrete layers are deposited on top of each other with no need for formwork [3,4]. While the outlook for 3DCP is promising, there is also a multitude of obstacles that need to be overcomeone of which is the integration of reinforcement [5,6]. Developing viable reinforcement methods for printed structures is essential to move this technology to the next level [7].…”

“…While multiple large scale projects have been realized, their structural integrity has been achieved in traditional ways, referring to solutions used in unreinforced masonry structures or creating compression structures [5,45]. None of the integrated reinforcement concepts developed have been used as primary reinforcement on a large scale as of yet.…”
