Carbonate Micromotors for Treatment of Construction Effluents.

Concrete in construction has recently gained media coverage for its negative CO footprint, but this is not the only problem associated with its use. Due to its chemical composition, freshly poured concrete changes the pH of water coming in contact with the surface to very alkaline values, requiring neutralization treatment before disposal. Conventional methods include the use of mineral acid or CO pumps, causing high costs to building companies.
