Abstract
Concrete is a construction material that is used world-wide because of its first-rate properties. However, the drawback of this material is that it easily cracks due to its low strength. There are many papers which discussed about the various strain of bacteria. Self-healing agents such as Bacillus Sphaericus. Calcium lactate are used to heal the cracks in concrete. When the bacteria is mixed with the concrete the calcium carbonate precipitates forms and these precipitates filling the crack and makes the cracks free concrete. A comparison study was made with concrete cube, cylinders and beams subjected to compressive, split and flexural strength test with or without the bacteria. It was found that there was high increase in strength and healing of cracks subjected to loading on the concrete specimens.
