On the Applicability of a Precursor Derived from Organic Waste Streams for Bacteria-Based Self-Healing Concrete

Bacteria-based self-healing concrete has the ability to heal cracks due bacterial conversion of incorporated organic compounds into calcium carbonate. Precipitates seal cracks, theoretically increasing service life constructions. The aim this paper is propose a precursor for bacteria-based derived from waste streams, produced in line with circular economy principle and ideally more affordable than other substrates. To verify applicability proposed healing agent, some fundamental requirements system are studied, such as its influence on functional properties, crack sealing capacity evidence activity concrete.
