T-17 Methyl Methacrylate (MMA) Polymer Concrete Patching Material is designed for use on new construction and rehabilitation of bridge decks, expansion joints, bearing pads, and other concrete structures and is a 100% reactive, pre-packaged, two component solvent-free material system.
Features and Advantages
- Wide Application Temperature Range (14-100 degrees F)
- Fast Setting (45 min. at 70 degrees F)
- High Early Strength
- Strong Chemical Bond (no cold joints)
- Chemical Resistant
- UV Light Resistant
- Freeze-Thaw Resistant
Easy to Use, No Special Tools or Trades Needed Patch Material
Transpo T-17 can be used as a neat mortar for grouting or thin applications (1/2” deep maximum). It also can be filled with special coarse aggregate and used for installations of 12 inches or more in a single pour. This system is to be used on horizontal concrete surfaces, on grade, above and below grade. The rapid curing time assures a quick return to service. T-17 is easy to handle in all working conditions and requires no special tools or equipment.
Testing has shown T-17 can be considered an alternative to UHPC.
Application of T-17 requires minimal labor and standard portable concrete mixing equipment. A thin coat of T-41s methyl methacrylate primer should be used to seal the existing concrete surface and increase the bond strength of the T-17 to the Portland cement concrete (PCC) subtrate. Because of its high strength, chemical resistance, and rapid cure, T-17 can be used for repairs and rehabilitation of numerous concrete structures including:
- Concrete Bridges
- Concrete Spall Repair
- Precast Bridge Deck Closure Pours
- Structural Grouting
- Partial or Full Depth Concrete Patch
- Expansion Joint Headers
- Structural Bearing Pads
- Load Transfer Devices
- Airport Runways
- Parking Deck Repair
