Abstract
Despite its versatility in construction, concrete is known to have several limitations. It is weak in tension, poor in ductility and low in resistance to cracking. Its strength and durability suffer due to physical stresses, biogenic corrosion and chemical attacks. Cracks and fissures are typical signs in such situations. An attempt has been made to use a novel thermophilic hot spring bacteria to repair cracks and increase the durability in specimens of concrete/mortar. Mortar samples incorporating bacteria and cured in hot condition, showed a significant decrease in sulphate and water absorption capacities and a significant increase in compressive strength. Ultrasonic velocity test conducted on such samples confirmed more compactness in the sample. The bacteria incorporated concrete showed better performance in cracks repairing compared to the normal cement-sand mixture. The results clearly showed that remediation for cracks and durability of concrete structures can be enhanced with the addition of bacteria optimised at a cell concentration of 105 cells/ml water.
