Microban International and MarMac Applied Infrastructure Sciences (AIS) have launched MarMac’s Concrete Admixture AMX 5500, a concrete protectant that integrates Microban’s antimicrobial technology into a concrete admixture product.
AMX 5500 inhibits damaging bacterial growth in treated concrete and is designed for use in various forms of concrete. This antimicrobial admixture provides a new solution for the building materials industry to help prevent both staining and Microbial-Induced Corrosion of Concrete (MICC).
“Microban’s partnership with MarMac is a story of like-minded innovators seeking solutions for our customers,” said Steve Lutes, director of business development at Microban. “This is an exciting collaboration. Integrating antimicrobial technology into the manufacturing process of building products can help avoid product degradation, and we’re thrilled to see this product sustainability solution come to life with MarMac.”
Microban’s researchers and product development team worked in partnership with MarMac’s AIS laboratory to integrate antimicrobial technology into MarMac’s AMX 5500, offering permanent concrete protection from bacterial growth, subsequent staining and corrosion. By utilizing Microban antimicrobial technology, AMX 5500 creates an inhospitable environment for bacteria growth because the active ingredient works to rupture the microbial cells and terminally disrupt the cell walls of fungi, molds and mildew. The product protection won’t alter the visual appearance of cured concrete, won’t wash away and lasts the lifetime of the treated structure.
“In the research, design, testing, and production of AMX 5500 we took advantage of MarMac’s 70+ years of experience in the industry to identify a real issue and provide a solution for the industry. Our customers came to us with this problem and Microban stepped up immediately to provide the best technologies and product to help,” said Jamie Martin, president of MarMac’s AIS division. “What made this product successful and what makes this partnership exciting is experience combined with the extraordinary capacities of Microban. Beyond that, MarMac and Microban are both committed to driving continuous improvement in building materials and delivering effective solutions.”
Microban-powered AMX 5500 is for construction environments and products used in humid and challenging environmental conditions, such as sewer or sanitary infrastructure, where sulfide producing microbes commonly damage infrastructure.
AMX 5500 also reduces aesthetically damaging stains from molds and mildews in a variety of commercial and residential concrete, from parking garages and commercial buildings to sidewalks, driveways, patios and pool decks. The product may be used in any new concrete structure requiring permanent product protection from bacterial growth and MICC, based on standard lab test method ASTM C1904-20.
In fact, ASTM testing of the MarMac’s Concrete Admixture AMX 5500 with Microban has shown that treated concrete retains 42.1% more strength compared to untreated concrete in controlled laboratory degradation testing. Independent and third party testing also certified AMX 5500 for use in the inhibition of mold and mildew growth staining in and on concrete.
Additionally, AMX 5500 is safe to use and has minimal potential environmental impact. “We were able to design a water-based, ultra-low VOC formulation, which when used properly is both safe and effective,” said Dr. Timothy Boone, director of formulations at MarMac AIS. “This product reflects our commitment at AIS to take advantage of very new technologies to create safer and more effective chemistry products which help protect our world’s infrastructure.”
“We’re committed to helping manufacturers across multiple industry sectors improve their products through use of Microban antimicrobial technologies,” said Michael Ruby, president of Microban. “We are proud to help power MarMac products for the residential, commercial pour-in-place, and precast concrete infrastructure markets in prolonging the functional life and aesthetic performance of concrete through AMX 5500. We look forward to expanding our partnership in the future to develop more cutting-edge solutions for downstream concrete customers.”
