Abstract

Abstract

Building industrialization and construction intelligence have become the current development trend. With the application of 3D printing technique in the construction field, the mechanical properties of 3D printed components need to be further studied. As one of the main components, mechanical properties of the wall are crucial to the performance of printed buildings under vertical load. Therefore, eight 3D printed concrete walls were designed with different section forms and material strengths, and the axial compression test was carried out. It was found that the two ends of printing walls were the main parts subjected to the external loads, and the failure began at both ends. The arrangement of ribs in the 3D printed wall could enhance the connection between the two wallboards, improve the integrity of the wall and enhance the bearing capacity of the 3D printed wall. The printed wall with higher cement strength had higher section stiffness, smaller vertical displacement and higher cracking load.
