T-17 Fast Setting MMA Polymer High-Strength Concrete Patching Material
T-17 is used on airports around the country for fast permanent repairs* to runways and taxiways. Emergency repairs in the runway safety area are both costly and disruptive to airport operations. Using a patching material like T-17 polymer concrete to make the repair assures the repair will be cured to full hardness in less than 45 minutes and will last indefinitely or until the next scheduled maintenance of the touch area.
*Refer to the FAA Circular Advisory on Guidelines and Procedures for Maintenance of Airport Pavements (AC 150/5380 6C) for more details on pavement maintenance.
Features and Advantages
- Wide Application Temperature Range (14-100° F)
- Fast Setting (45 minutes at 70° F)
- High Early Strength (Compressive strength of 2,500 psi @2hrs and 8,000-9,000 psi @24hrs)
- Strong Chemical Bond
- Freeze-Thaw Resistant
Easy to Use, No Special Tools or Trades Needed
T-17 can be used as a neat mortar for grouting or thin patches, it can be filled with prepackaged coarse aggregate and used for partial or full-depth patching in a single pour. The rapid curing time assures a quick return to service. T-17 is easy to handle and requires no special tools or equipment.
Application of T-17 requires minimal labor and standard concrete mixing equipment. A thin coat of primer is used to seal the existing concrete surface and increase the bond strength of the T-17 to the Portland cement concrete (PCC) sub-straight. Due to its high compressive strength, excellent bond strength, and rapid cure, T-17 can be used for concrete repairs and rehabilitation.
