Toh rebar cracking, often caused by the corrosion of steel reinforcement within concrete, is a serious structural concern. When rebar is exposed to moisture or chemicals, it oxidizes and expands, exerting internal pressure that forces the surrounding concrete to crack. Addressing these cracks early—through methods like epoxy injection or applying a rust converter —is essential to maintaining the long-term integrity and safety of the structure.
As infrastructure ages, the early detection and classification of structural cracks are vital for safety and cost-effective maintenance. This paper examines the role of advanced 3D modeling—specifically the Toh Make Rebars toh rebar crack
