They produce 60-80 milligram of calcium carbonate 'per fiber', per 30 hours. I'm interested to know how they keep the bacteria alive over time, through the concrete curing process (high temperatures, high level of carbon dioxide, making any liquids in the vicinity highly acidic), and how the bacteria remain viable over time. Concrete we consider to last over decades, or a century?
