Mesoscale failure mechanisms and strength prediction of 3D ‐printed concrete ribbed walls

This study investigates the mechanical behavior, failure mechanisms, and strength prediction of 3D‐printed concrete ribbed walls under compression, shear, and combined compression–shear loading. Four wall specimens with different internal rib configurations were tested under axial compression, while digital image cor...

Self-Healing Bio-Concrete from a Process-Driven Perspective: A Review of Mechanisms, Challenges and Multi-Scale Simulation Methods

Microcracks in concrete are a key factor affecting structural durability, and traditional repair methods struggle to achieve the long-term sealing of deep-seated microcracks. Self-healing bio-concrete, based on the technology of microorganism-induced calcium carbonate precipitation, utilises pre-embedded microbial repa...
