Bacteria Based Healing of Cracks with The Use of Pseudomonas and Kocuria in Concrete

The present study aims to find the mechanical properties of bacterial concrete. Two types of bacterial species were used, i.e., Pseudomonas BG and Kocuria 2M7 for concrete. SEM was done to confirm that applied micro-organism can produce calcium carbonate in concrete for healing of cracks or not. Due to production of calcium carbonate crystals, it is necessary to check the strength properties of concrete. The compressive strength and split tensile strength were increased as we apply the micro-organism to the concrete. For the durability aspect, capillary water absorption (sorptivity) of concrete core specimen was measured with and without bacteria. The result of effect of two different strains that is pseudomonas BG and kocuria 2M7 were also compared to check which one is ideal for concrete.
