ice for concrete cooling

Concrete Cooling - North Star Ice

Flake ice is a preferred method for cooling concrete on mass pour projects such hydro dams, nuclear power plants, and ready-mix. Flake ice reduces heat generated during the concrete curing process making it the best choice in critical low temperature concrete specifications.

Using Chilled Water or Ice to Slow the Cement Hydration ...

Jul 30, 2018 · Ice has a two-way cooling effect. First it draws heat from the concrete for melting of ice, then the resulting water at 32°F provides continuing cooling capacity. Using these techniques can make all the difference in the success or your project. Special measures have to be taken during hot weather.

Concrete Cooling – Vogt Ice

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; Vogt 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.

Concrete cooling plants - Recom Ice Systems

Using flake ice has a much bigger impact on the temperature of the concrete mix, compared to using cold water, due to the large amount of heat that is needed to melt the ice. To cool down 1 m³ of concrete by 1°C, about 33kg of cold water is necessary, while only 7.5kg of flake ice has the same effect. To use this method, an ice plant is built near the construction site. An ice factory consists at least of a containerized flake ice machine (i.e. Recom CF900-ET) and an ice storage.

The Flake Ice Plant in Concrete Cooling Systems

Apr 10, 2015 · For most concrete cooling system, cold water from the water chilling plant and cold water tank makes its way into the flake ice plant. This cold water is then sprayed onto the surface of refrigerated drums that are so cold that the water freezes instantly into ice. In fact the drums are so cold that the ice is often sub-cooled to below freezing.

Using Crushed Ice in Concrete| Concrete Construction Magazine

The use of ice does effectively accomplish the purpose of cooling the mix in hot weather and is far more effective than cold water. One rule of thumb for determining how much ice to use is that the concrete temperature can be reduced one degree F for each two percent of total water replaced by ice.

Concrete Cooling - SEMCOLD

This method typically involves the use of ice and it is important to ensure that the ice will thoroughly melt during the process so as to avoid gaps and uneven hydration in the final concrete. Post-Cooling – Post-cooling is performed after the concrete has been poured by pumping chilled water through a network of pipes located within the concrete. This method is effective for very large projects such as dam construction.
