MarMac’s Concrete Admixture AMX 5500 is a Microban®-powered, liquid antimicrobial concrete additive that inhibits damaging bacterial growth in treated concrete. AMX 5500 is especially beneficial in sanitary sewer and other wet/humid environments where harmful microbes often thrive. This product may be used in any new concrete structure requiring permanent product protection from bacterial growth and Microbial-Induced Corrosion (MIC1).
- Stained
- Corroded
- Mildew
- Clean
- Minimal Pitting
- Unblemished
The Microban® active ingredient used in MarMac’s Concrete Admixture AMX 5500 creates an inhospitable environment for bacteria growth by working to to rupture their cells and terminally disrupt the cell walls of fungi, molds, and mildew.
Benefits of Treated Concrete
- Microban®-powered antimicrobial helps prevent corrosion (M.I.C.1)*
- Preserves strength: Over 40% stronger concrete vs untreated*
- Microban Antimicrobial Technology™ lasts the lifetime of the structure
- Ultra-low VOC formula
- Fights damaging bacterial growth & subsequent stains
- Inhibits growth of mold & mildew
- Makes for longer-lasting, higher quality structures
- Reduces maintenance: Helps keep concrete cleaner
1 Microbial-Induced Corrosion (of Concrete); * Based on standard lab test method ASTM C1904-20.
Visually undetectable
MarMac’s Concrete Admixture has no adverse side effects. There is no change in the cure time, finishability, and coloration/shade when compared to traditional “mix water” concrete. Visually, the only noticeable difference is long-term, fresher, cleaner concrete. The final cured AMX 5500-treated concrete retains all the same physical specifications with the bonus of antimicrobial properties.
Saves time & money
Our Microban®-powered admixture protects concrete finishes and lowers overall maintenance. Fewer required cleanings reduces labor and the need to hire professional pressure washing services or renting equipment, and minimizes water & chemical usage. The results are: less mess, less time, and lower cost.
Combats corrosion
Common Applications
Protect your next concrete project from MIC, bacterial stains, and fungal growth (mildew, mold, lichen, algae).

24/7 protection by Microban®
The Microban Antimicrobial Technology™ used in our Concrete Admixture AMX 5500 remains a permanent part of the concrete structure, continuously fighting stain & corrosion-causing microbe growth. The protection will not wash away, break down, or fade over time, resulting in cleaner, longer-lasting concrete.

AMX 5500 was rigorously tested against the ASTM C1904 – 20: Standard Test Methods for Determination of the Effects of Biogenic Acidification on Concrete Antimicrobial Additives and/or Concrete Products.
The tested percent strength reduction for the treated admixture is much lower than that of the control specimen. The ‘5-alpha- admixtureʼ showed only an 11% decrease in strength. “This strongly indicates that the quaternary silane additive is extremely effective at reducing the strength loss of the cement due to MIC”.
This product has been tested by an outside independent microbiological laboratory for its efficacy against the harmful type of destructive micro-organisms particularly attacking concrete infrastructures.
The test protocol used was that of the modified ISO 22196:2011 (JIS Z2801) – ‘Antibacterial efficacy testing construction materials.ʼ The test was performed in triplicate against an exposure time of 24 hours. The test organism used was Serratia marcescens.
AMX 5500 exhibited a microbial (bacterial) ‘killʼ of >99.999% (or 5 log reduction) of the bacteria after 24 hours of exposure, clearly demonstrating superlative performance as an antimicrobial admixture for cementitious infrastructures.
AMX 5500 is packaged in a distinctive 5-gallon pail (gray) with a white top and an ‘anti-gluckʼ spout for safe and easy use. Each 5-gallon pail has a net weight of 37.85 lbs (17.17 kg).
When stored in the original and unopened container in a well-ventilated area between 41-100 °F (5-28 °C), AMX 5500 has an approximate shelf life of 18 months from the date of manufacture. Keep away from excessive heat and open flame.
Protect from freezing or near freezing conditions. Should the admixture be left or stored in such conditions be sure that it has not layered or has become exceedingly cloudy. Heat the solution in its container in an ambient temperature of around 65-75 °F for approximately 20-30 minutes stirring occasionally. This should remedy the situation and be able to be used.
The usual handling and safety precautions should be observed when using AMX 5500. These include the measures described in federal, state, and local health and safety regulations and requirements.
The workplace should have thorough ventilation. Handle in accordance with good industrial hygiene and safety practices. Protective eyewear, disposable coveralls, aprons, or other protective clothing, along with appropriate nitrile or other protective chemical resistant gloves is recommended. Wash hands thoroughly before eating, drinking, or smoking after the use of AMX 5500.
AMX 5500 is a premixed, water based, ready for use product to be added while mixing concrete for various infrastructures. Mix AMX 5500 thoroughly before use if it has been sitting for an extended period of time. Do not dilute AMX 5500. It does not need it.
The total volume of AMX 5500 used in a particular application is to be considered “mix water” and must be considered when calculating the total water to concrete (w/c) ratio.
Approximately 122-128 fl oz (0.95-1.00 gallon) is enough AMX 5500 to adequately treat one cubic yard (1 yd3) of concrete in most applications. Due to variation in cement response, it is important that set time and slump retention of the proposed mix be thoroughly tested and evaluated in the light of job requirements.
Add the required quantity of AMX 5500 to your concrete while continuing to tumble the concrete mixing. Be sure to mix the concrete an additional 5-10 minutes so that AMX 5500 is thoroughly distributed throughout the concrete mix.
