EXPERIMENTAL RESEARCH ON THE INFLUENCING FACTORS OF THE BOND PERFORMANCE BETWEEN PRINTED CONCRETE AND REBAR

摘要

摘要: 采用逐条挤出、层叠成型的混凝土打印工艺使得打印混凝土材料力学性能呈现明显的各向异性，加之其配筋方式受限于打印工艺，仅可在水平层间放置钢筋再叠层打印，使得打印混凝土与钢筋的黏结性能受打印工艺、钢筋放置等诸多因素影响。通过设计正交试验研究了钢筋直径、打印混凝土材料强度、打印工艺、钢筋置入方式对钢筋与打印混凝土材料黏结性能的影响规律，得出应优先采用顺纹打印工艺并埋入放置钢筋的方式，以提高钢筋与打印混凝土的黏结性能。

Abstract: The concrete printing process of one-by-one extrusion and layer forming makes the mechanical properties of the printed concrete material show obvious anisotropy. In addition, the reinforcement method is limited by the printing process. Rebar can only be placed between horizontal layers and then laminated to print. The bonding performance between concrete and steel bars is affected by many factors such as printing process and steel bar placement. In this paper, the effects of steel bar diameter, strength of printed concrete, printing technology and placement of steel bar on the bonding properties of steel bar and printed concrete were studied by designing orthogonal experiment. It is concluded that the method of printing along the lines should be preferentially used and the method of embedding the reinforcing bars should be buried to improve the bonding performance between the reinforcing bars and the printed concrete.
