In recent years,the application area of 3D concrete printing technology has shifted from ar-chitectural landscape to house,bridges and other typed load-bearing structures.Therefore,the favora-ble long-term and durable performance of 3D printed concrete materials is of crucial significance to promote the structural application.This paper evaluates 3D printed concrete materials from three as-pects:miscrostructure heterogeneous structure,shrinkage cracking performance and durability per-formance,to clarify the main factors affecting the durability performance.This paper can provide sci-entific guidance and suggestions for optimizing the performance of 3D printed concrete materials,thereby promoting the rapid and high-quality development of 3D printing in the field of civil engineer-ing and construction.
