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 |
