| Abstract Scope |
3D concrete printing (3DCP) is a key focus of digitalization in the construction industry, with the abilities of better-quality control, lower cost, construction time, and un-paralleled aesthetic, under the "construction 4.0". The significance of predicting the ultimate mechanical performance of the produced structure increases, as we get to more advanced, valuable, and larger-scale applications of 3DCP. The objective of this study is to analyze fresh material’s properties for the newly developed green geopolymer materials for the development of numerical and simulation models. Unconfined material testing and tri-axial compressive testing have been performed for Elastic modulus, Poisson ratio, Cohesion coefficient, friction angle and density calculation. The study also performs a comparative analysis of the developed numerical model and simulation with the experimental study for different geometrical and printing parameters. Based on the analysis of the results, different new printing strategies have been proposed to increase the overall performance of the process. |
