Concrete Cooling
Use: When concrete cures at temperatures above 70 ° F the following occurs:
- Loss of strength
- More cracking
- Rapid setting(need to finish quickly)
- Increased water demand
Solutions:
These detrimental effects can be offset by cooling the aggregate (water chilling or using ice in place of water in the mix of cement and aggregate.
Turbo equipment application:
- Ice makers(C series / Tig / Tigar), rake storage bins (CB and Automatic Rakes ), Pneumatic delivery systems(Blower, rotary valve and control systems) for concrete mix.
- HTD plate fluid chillers for water chilling
- Thermal Energy Storage(HP and IGC) for water chilling.
Features:
Turbo fragmented ice benefits:
- Quick release of BTU's to the cement mix.
- No lumping of ice product
- Variable ice thickness control for desired ice type
- Storage and delivery systems to integrate in to any plant process
Chilled water benefits:
- Used to cool aggregate prior to mixing
- Generated from the Thermal Energy Storage system
- HTD fluid chiller can be used produce chilled water
- 33 ° F water temperature available for chilling
- Use off peak energy with TES systems
Typical applications
- Dams for inland reservoirs
- River lock and dam systems
- Highway construction
- Large general construction pours
Also required where:
- Critical strength specifications for concrete must be met
- High ambient temperatures are experienced
- Areas where aggregate temperatures are high
