Five Star Structural Concrete – 50 lb Bag

Five Star Structural Concrete® is a single-component, high-early-strength repair material designed for fast turnaround and long-term durability. Engineered with migrating corrosion inhibitors, it forms a permanent bond with existing concrete and delivers exceptional freeze/thaw resistance, low shrinkage, and chloride permeability well below 1,000 coulombs. It can be applied from 1/4 inch to 12 inches in one pour and is ready for coatings within 8 to 24 hours.

Key Features:

Fast-setting—2,500 psi in 3 hours
High final compressive strength up to 8,000 psi
Low shrinkage for dimensional stability
Resists chloride ion penetration (<1,000 Coulombs)
Outstanding freeze/thaw durability
Can be extended with coarse aggregate

Applications:

Concrete structure repairs
Machinery foundation rebuilds
Concrete floor patching and overlays
Coating base repairs
Marine and hydraulic structure restoration
