Description
For the construction industry, MIC is a serious challenge that causes billions of dollars in damage to wastewater and sewage-related concrete structures every year. The root cause is the thiobacillus bacteria found in sewage and septic environments, which converts hydrogen sulfide gas (H2S) into biogenic sulfuric acid (H2SO4). The presence of sulfuric acid on concrete surfaces can unleash highly localized and rapid corrosion processes that eat away the cement paste of the concrete matrix. This, in turn, can quickly expose the embedded reinforcement steel of underground concrete sewage systems to water, oxygen, CO2, and chlorides – resulting in catastrophic corrosion-related failures in the concrete.
Products Used
Bluffton Precast added Penetron’s antimicrobial admixture to the concrete mix for all precast elements. Identical to the well-known PENETRON ADMIX, a crystalline concrete waterproofing admixture, the antimicrobial properties of the admixture are permanent; it becomes part of the concrete matrix and is leach resistant, even repeated contact with bacteria does not lessen the effectiveness of the admixture.
