MarMac AIS has launched Admixture AMX 5500, a water-based, ultra-low VOC agent formulated with antimicrobial technology to curtail bacterial growth throughout the concrete surface or structure service life. The Microban International agent in AMX 5500 works to rupture microbial cells and terminally disrupt fungi, mold and mildew cell walls without altering the visual appearance of cured concrete. MarMac AIS and Microban are promoting the admixture as “an innovative new solution for the industry to help prevent both staining and microbial-induced corrosion.”
AMX 5500 suits concrete in all environments, especially those exposed to humidity or challenging environmental factors such sulfide-producing microbes typically found in sanitary sewer infrastructure. The admixture is also effective in reducing aesthetically damaging stains from molds or mildews in a wide variety of commercial or residential concrete conditions, from parking garages and buildings to sidewalks, driveways, patios and pool decks. The product can be used in any new concrete structure requiring a) permanent protection from bacterial growth or microbial-induced corrosion; and, b) performance as demonstrated in ASTM C1904-20, Standard Test Methods for Determination of the Effects of Biogenic Acidification on Concrete Antimicrobial Additives and/or Concrete Products.
“We are proud to help power MarMac products for the residential, commercial cast-in-place, and precast concrete markets, prolonging functional life and aesthetic performance through AMX 5500,” says Microban President Michael Ruby. “We look forward to expanding our partnership to develop more cutting-edge solutions for downstream concrete customers.” — www.marmac.com/ais
