MasterEmaco T 545DOT: Very rapid-setting chemical-action repair mortar

Formerly: Set 45 Cal Tran


How does MasterEmaco T 545DOT work?

MasterEmaco T 545DOT is a one-component magnesium phosphate-based patching and repair mortar. This concrete repair and anchoring material has a minimum initial set time of 15 minutes and a minimum final set time of 25 minutes @ 70° F and takes rubber tire traffic in 45 minutes.

Recommended uses:

  • Interior and exterior
  • Horizontal and formed vertical overhead repairs
  • Applications requiring high-early strength gain
  • Structural concrete repairs
  • Partial and full-depth repairs
  • Grouting applications such as anchor bolts, rebar, dowel rods and precast applications

What are the unique features of MasterEmaco T 545DOT?

  • Only requires the addition of potable water
  • Wide temperature use range from below freezing to hot weather exposures
  • Air cure only, no wet curing compounds required
  • Coefficient of thermal expansion similar to Portland cement concrete for more permanent repairs
  • Higher sulfate resistance than conventional mortars

What are the benefits of MasterEmaco T 545DOT?

  • Reaches 2,000 psi compressive strength in 1 hour to rapidly return repairs to service
  • Very low drying shrinkage for improved bond to concrete for repair and anchoring applications
  • Resistant to freeze/thaw cycles and deicing chemicals so it is usable in most environments
