This study explores the potential impact of natural soil on concrete crack self-healing in sub-surface structures. Three types of pre-cracked cement mortar samples were prepared for laboratory experiments, with some samples inoculated with bacterial healing agents, others supplemented with nutrients to attract indigenous soil bacteria, and plain mortar served as …
The use of bacteria-based self-healing concrete for sub-structures in ground conditions is an area of increasing interest for enhancing the durability and longevity of infrastructure. In line with this objective, the present study investigates the bio-self-healing performance when a cementitious material is embedded in clay soil with varying chemical exposures …
The provision of suitable incubation environments is vital for successful implementation of bio self-healing concrete (bio-concrete). We investigated the effect of soil incubation to examine if the self-healing process can be activated in comparison with the conventional incubation environment (water). The data was collected from laboratory-scale experiments conducted on mortar …
Concrete is the most used construction material worldwide for infrastructure projects. Due to deterioration, regular maintenance works are necessary to seal the concrete cracks and restore durability. In Europe, infrastructures such as tunnels, bridges and earth retaining walls alone cost approximately 5 billion EUR per year. Self-healing strategies (particularly bacterial-based …
