Abstract

Concrete water tanks are highly vulnerable to cracking, leakage, permeability, and durability deterioration due to continuous exposure to hydrostatic pressure and environmental effects. Conventional repair techniques are often costly and temporary in nature. This study investigates the performance of self-healing bacterial M30 concrete for water tank applications using microbial-induced calcium carbonate precipitation (MICP) technology. Bacillus subtilis bacteria were incorporated into M30 concrete at two bacterial concentrations, namely BC-1% and BC-2%, and compared with conventional concrete. Experimental investigations were carried out to evaluate compressive strength, split tensile strength, flexural strength, water absorption, permeability, and crack-healing efficiency. Results revealed that bacterial concrete significantly improved mechanical strength and durability characteristics due to calcite precipitation within pores and cracks. The BC-2% mix exhibited the highest crack-healing efficiency and lowest water permeability. The study concludes that bacterial self-healing concrete can provide a sustainable and durable solution for water-retaining structures by reducing leakage, improving durability, and extending service life.

Keywords: Self-healing concrete, bacterial concrete, Bacillus subtilis, M30 concrete, water tanks, microbial-induced calcium carbonate precipitation.
