Abstract:Incorporating bacteria into concrete has been proposed as a method of mitigating the negative impacts of concrete cracking, and may also lead to increased strength and durability through calcium carbonate precipitation and porosity reductions by the bacteria. This study aimed to increase understanding of the use of microorganisms in concrete by investigating: performance of axenic and environmentally-derived bacteria cultures to increase resiliency of bacteria for use in upscaled use in concrete systems; effects of curing method and exposure to hot and cold temperatures and salts; and performance of bacteria in a pilot scale pavement application.
