BASF antimicrobial admixture suits underground, environmental structures

BASF Admixture Systems has formulated the integral MasterLife AMA 100 admixture to protect concrete structures from biodeterioration by destroying bacteria and micro-organisms that cause microbial-induced corrosion upon contact through an electrophysical mechanism. Sewage or wastewater exposure and subsequent reactions can cause premature deterioration in concrete pipes, manholes and other conveyance or drainage structures, resulting in increased maintenance and life-cycle costs plus compromised aesthetic appearance.

Antimicrobial technology imparts surface characteristics inhospitable to bacteria and micro-organisms. BASF Admixture Systems applies similar principles in formulating MasterLife AMA 100 for wastewater exposure-prone concrete surfaces and structures.

“Expanding the service life of concrete structures is among BASF’s priorities for providing sustainable solutions for the construction industry,” says Admixture Systems, Industry Manager Kenneth Kruse. “MasterLife AMA 100 admixture is one of the technologies that can extend the lifespan of sewage or wastewater concrete structures by disrupting the process that leads to microbial-induced corrosion.”

MasterLife AMA 100 is mixed in during the batching process, and becomes an integral part of the concrete for the life of the structure. It provides effective and long lasting protection, even if the concrete surface gets abraded. Repeated contact of MasterLife AMA 100-treated concrete with bacteria will not diminish antimicrobial product effectiveness. —
