BASF Debuts Antimicrobial Admixture for Concrete

BASF’s Admixture Systems unit debuted a new product to protect concrete structures from corrosion caused by bacteria and micro-organisms on Monday. The German chemical corporation’s MasterLifeAMA 100 is mixed with concrete during the batching process to provide protection from biological causes of concrete degradation.

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

Concrete used in wastewater and sewage application often corrodes over time as it comes into contact with bacteria and micro-organisms, raising maintenance costs over the concrete’s life-cycle. BASF said its new product prevents the corrosion by using an electrophysical mechanism that destroys the offending micro-organisms and bacteria.

“It provides effective and long-lasting protection, even if the concrete surface gets abraded,” said BASF’s press release announcing the new product. “Repeated contact with bacteria with concrete treated with MasterLife AMA 100 admixture will not diminish the effectiveness of the antimicrobial product.”
