Large Particle 3D Concrete Printing—A Green and Viable Solution

Abstract: The Large Particle 3D Concrete Printing (LP3DCP) process presented in this paper is based on the particle bed 3D printing method; here, the integration of significantly larger particles (up to 36 mm) for selective binding using the shotcrete technique is presented. In the LP3DCP process, the integration of large particles, i.e., naturally coarse, crushed or recycled aggregates, reduces the cement volume fraction by more than 50% compared to structures conventionally printed with mortar. Hence, with LP3DCP, the… Show more

“…Recent technological developments, however, make such a clear classification difficult (see Figure 5). For example, the use of coarser aggregate (>5 mm) as a particle bed has given rise to other special forms of SPI: (1) aggregate bed 3D concrete printing (A3DCP) [82], (2) large particle 3D concrete printing (LP3DP) [83], and (3) injection 3D concrete printing [84].…”

“…The integration of flat inlays has been tested for different particle bed printing techniques so far (e.g. Large particle 3D concrete printing [39]). Furthermore, a double curved mesh has been integrated laterally into a SC3DP-wall-element.…”

“…Insbesondere werden alternative faserbasierte Bewehrungswerkstoffe wie Glas‐ oder Kohlenstofffasern untersucht. Das DBFL bietet die Grundlage für das neu entwickelte Fibre‐Winding‐Verfahren, welches eine individualisierte robotische Einbringung von kontinuierlicher Faserbewehrung in additiv gefertigte Betonbauteile ermöglicht, die in Zusammenarbeit mit Teilprojekt A04 im SC3DP‐Verfahren hergestellt werden (Bild 3) [8–11]. Beim Teilprojekt C05 Jointing Principles for AMC Components werden unterschiedlichste Verbindungsarten für Betonbauteile untersucht.…”
