Very rapid-setting chemical action mortar
Formerly: Set 45 and Set 45 HW
How does MasterEmaco T 545 and T 545HT work?
MasterEmaco T 545 is a one-component magnesium phosphate-based mortar. Offered in two formulations: T 545 for ambient and substrate temperatures below 85° F (29° C) and T 545HT for ambient and substrate temperatures ranging from 85 to 100° F (29 to 38° C).
Interior and exterior
Horizontal and formed vertical overhead repairs
Applications requiring high early-strength gain
Structural concrete repairs
Partial and full-depth repairs
Cold temperature repairs
Grouting applications such as anchor bolts, rebar, dowel rods and precast applications
What are the unique features of MasterEmaco T 545 and T 545HT?
Single component to just add water and mix
Takes rubber tire traffic in 45 minutes
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 545 and T 545HT?
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
