13 Δεκ 2023 · Bio-concrete is a potentially CO2-neutral alternative to conventional Portland-cement-based concrete, since no process-related carbon dioxide emissions are generated during...
Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.
1 Μαρ 2016 · Concrete is one of the most widely used construction materials and has a high tendency to form cracks. These cracks lead to significant reduction in concrete service life and high replacement...
1 Σεπ 2023 · In bio-concrete, along with autogenous sealing, aerobic bacteria stimulate the self-healing properties providing CaCO 3 using the metabolic conversion of nutrients.
29 Ιαν 2016 · The influence of bio-based healing agents on permeability and water absorption of concrete has been reported by several studies. As can be seen from Table 2 , permeability and water absorption of concrete structures have been decreased by the presence of bio-based agents.
26 Μαΐ 2024 · What is Bio-Concrete? Bio-concrete, also known as self-healing concrete, is an innovative material designed to repair its own cracks and damages autonomously, extending the lifespan of concrete structures. The primary mechanism behind bio-concrete involves the incorporation of bacteria and nutrients within the concrete mix.
