Concrete crack remediation by polyurethane-immobilized bacillus pasteurii
This paper reports the results of the scanning electron micrography (SEM) analysis of concrete crack remediation by polyurethane (PU)-immobilized Bacillus pasteurii whole cells. In SEM, encapsulated bacterial cells were identified throughout PU polymer matrices with some clumps. During remediation, calcite precipitation appeared in PU matrices as well as between the polymer and the concrete, in which cells were embedded in growing calcite crystals. Calcite in PU showed little effect on the elastic modulus and the tensile strength of the polymer, but increased the compressive strengths of concrete cubes whose cracks were remediated with PU-immobilized cells.
