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
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.
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
- 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
