3D Concrete Printing with Robot - Resulted Properties

3D concrete printing has revolutionised the construction industry by enabling the production of complex geometries and customised designs. Using 3D concrete printing technology in the construction field offers numerous advantages, such as design freedom, cost efficiency, and construction speed. Due to the process of extruding the concrete layer by layer, the 3D printed object will be orthotropic. Therefore, the objective of this study is to investigate how varying water content and printing direction affect the compressive strength of cast and printed cubes. Three different water-todry material ratios (w/d) were used: 0.140 l/kg, 0.145 l/kg, and 0.150/l/kg. The printed cubes were tested in three different directions: X, Y, and Z.
