Abstract

Self-healing concrete has great potential to enhance the durability of concrete structures without significantly increasing the initial costs. Among the self-healing approaches, vascular self-healing cementitious composite is capable of supplying healing agents to the cracked region in a continuous way or multiple times. However, the use of brittle materials as vascular makes it difficult to create vascular networks with complicated geometry. The recent development of additive manufacturing (AM, also known as 3D printing) promotes the fabrication of complicated vascular system for vascular self-healing materials. However, the application of AM in vascular self-healing cementitious materials is relatively rare. Therefore, this study focuses on understanding the behavior of 3D-printed vascular self-healing concrete with different printing parameters or vascular configurations.....
