Abstract
The present invention provides concrete-containing compositions, and methods of making and using the same, that allow for the prevention of microbially induced corrosion in concrete. In certain embodiments, the concrete-containing compositions comprise a cementitious substrate, and a formulation of heavy metal-laden, carbon-based sorbent.
