“…Buildability is also measured empirically, either by measuring the number of layers until failure [28,[97][98][99] or based on the deformation measured for a printed element after a given number of deposited layers [68,88,89]. Recently, Yuan et al [100] measured the deformation of the 3D printable concrete cast in cylindrical moulds when subjected to constant loads applied at regular intervals of time after its casting. The applied constant loads at regular intervals simulated the stacking of each layer in a 3D printing process.…”

“…Another method for indirectly investigating buildability concerns mechanical properties of fresh materials, including vertical deformation under load, green strength (i.e., strength immediately after extrusion), and rheological properties (especially yield stress). Panda and co-workers [43,98] conducted the plate stacking test to simulate incremental load on the lower layers and monitor the deformation behavior of the layers with no need to print, which is similar to the method presented by Perrot et al [99], Kazemian et al [56], Yuan et al [100], and Shakor et al [55,62]. Zhang et al [48] measured the very early strength by the green strength test [101].…”

3D-printing of cementitious materials is an innovative construction approach with which building elements can be constructed without the use of formwork. Despite potential benefits in the construction industry, it introduces various engineering challenges from the material point of view. This paper reviews the properties of extrusion-based 3D-printed cementitious materials in both fresh and hardened states. Four main properties of fresh-state printing materials are addressed: flowability, extrudability, buildability, and open time, along with hardened properties, including density, compressive strength, flexural strength, tensile bond strength, shrinkage, and cracking. Experimental testing and effective factors of each property are covered, and a mix design procedure is proposed. The main objective of this paper is to provide an overview of the recent development in 3D-printing of cementitious materials and to identify the research gaps that need further investigation.

In construction, three-dimensional concrete printing technology is an innovative method that opens new design possibilities, reducing the construction time process. The incremental material deposition allows organic shapes without formwork, a mandatory constraint in preparatory phases of conventional complex concrete structures. Nowadays, in three-dimensional printing for construction industry, concrete is the most used material due to its workability, extrudability, and pumpability properties favorable for the printing conditions. Hence, this composition still has a poor sustainable efficiency due to the high levels of Portland Cement. In this research, a reduction of this material was studied and experimented searching for a mortar composition with better ecological footprint, with the objective of decreasing the CO2 emissions. A bibliometric analysis was made to study the constituents of a mortar for three-dimensional printing and respective dosage. The knowledge acquired in the analysis of the compositions contributed to the development of mortars with lower Portland Cement content. A mechanical extruder was used to check the extrusion capacity of the developed mortars, and the best compositions are presented.
