Five Star Structural Concrete® ESX is a high early strength, single component, pre-extended, permanent concrete repair material. The product achieves a self-consolidating concrete (SCC) consistency at maximum water dosage, enabling easy placement, excellent flowability, and superior encapsulation of reinforcement without vibration. The 45-minute working time facilitates deep/large volume pours in a single lift of up to 24 inches (610 mm). Five Star Structural Concrete® ESX produces a repair which is dimensionally stable, develops an integral bond to existing concrete, and restores structural integrity within hours of placement. Five Star Structural Concrete® ESX provides increased corrosion protection of steel reinforced structures with migrating corrosion inhibitor technology and very low chloride ion permeability.
