Five Star Structural Concrete ES-60
Five Star Structural Concrete ES-60 is a high-early-strength, single-component repair mortar engineered for hot weather. It holds a 60-minute working time at 90°F so deep, large-volume pours stay placeable in boiler rooms, warm plants, and summer placements. Pumpable batches, high six-hour strength, and migrating corrosion inhibitors restore structural concrete when ambient heat would kill a shorter mix.
Key Features
- 60-minute working time at 90°F
- Formulated for hot-weather and elevated-temperature placements
- High six-hour compressive strength
- Pumpable for deep, large-volume pours
- Migrating corrosion inhibitor technology
- Coat grouts and epoxies as early as 8 hours in elevated temperatures
Applications
- Hot-weather concrete repair
- Deep, large-volume structural and foundation repairs
- Boiler and furnace rooms
- Heavy industrial repairs and retrofits
- Bulk mixing and handling

Frequently Asked Questions
When should a contractor pick Five Star Structural Concrete ES-60 instead of Five Star Structural Concrete ES?
Use Five Star Structural Concrete ES-60 for hot-weather work at 90 F and above, where it still gives about 60 minutes of working time. For placements below 90 F, use Five Star Structural Concrete ES.
How long does Five Star Structural Concrete ES-60 stay workable at 90 F?
Five Star Structural Concrete ES-60 is formulated for about 60 minutes of working time at 90 F.
When can coatings go over Five Star Structural Concrete ES-60 in elevated temperatures?
Cement grouts, epoxy grouts, and epoxy coatings can go over Five Star Structural Concrete ES-60 as early as 8 hours after placement in elevated temperatures.
Is Five Star Structural Concrete ES-60 used in boiler and furnace rooms?
Yes. Five Star Structural Concrete ES-60 is used in boiler and furnace rooms, hot-weather concrete repair, and heavy industrial retrofits.
How soon can equipment be rebuilt with Five Star Structural Concrete ES-60 in very high temperatures?
Five Star Structural Concrete ES-60 can facilitate equipment rebuilds as early as 12 hours in very high temperatures.
How strong is Five Star Structural Concrete ES-60 at six hours at 90 F?
Five Star Structural Concrete ES-60 typically reaches about 3,000 psi at six hours when tested at 90 F.
