Determination of Bacterial Concrete Strength Using Bacillus Subtilis and Lightweight Expandable Clay Aggregate

This study examines the impact of bacterial concrete on strength and self-healing. Bacterial has better compressive strength, permeability, corrosion resistance, chemical precursors, alkalinity mechanical stress. Bacillus subtilis calcium lactate spore powder effects are explored in this study, influence form self-healing capacity to crack repair. The concentration 105 cells/mL is used with 0.3% cement. In another trial, lactates 0.5% cement lightweight expandable clay aggregate (LECA) 30% replaced coarse respectively. conventional cubes were molded dimensions 150 mm x mm, cylinders 100 200 a beam 500 mm. These specimens evaluated after 7 28 days cure. compressive, split tensile, flexural was raised by 23%, 8%, 7%, respectively when compared concrete. Thus, experimental findings reveal that at cells/ml cells substantial
