- Abstract
- Due to their porous nature and because they are prone to crack formation, mineral building materials are susceptible to a variety of degradation processes resulting from ingress and/or presence of water. In this research microbial calcium carbonate precipitation is used to protect the surface or heal the cracks of construction materials such as limestone or concrete. It was shown that the water absorption of mortar cubes may be decreased by the use of a bacterial surface treatment. Also the crack healing efficiency of this technique gave positive outcomes. Treatment of cracks with Bacilus sphaericus immobilized in silica gel resulted in a decrease in the water permeability of cracked concrete samples. TGA analysis indicated that CaCO3 crystals were precipitated inside the matrix. Currently the suitability of this biological repair technique to obtain self-healing properties in concrete is investigated.
