Concrete cooling systems are typically categorized into pre-cooling and post-cooling types, and are composed of several integrated subsystems working together. These commonly include a chilled water system, ice-making unit, ice storage and conveying system, ice delivery mechanism, and an automatic weighing system.
The concrete cooling system involves mixing flake ice directly into the concrete mixture. By utilizing the heat absorption during ice melting, this method effectively lowers the temperature of freshly poured concrete, preventing cracking caused by excessive heat. It is widely used in large-scale construction sites and infrastructure projects.
Working Principle: During the concrete mixing process, a controlled amount of flake ice is added. As the concrete undergoes hydration, the ice gradually melts, absorbing a significant amount of heat. This reduces the peak temperature inside the concrete, minimizing thermal stress and preventing temperature-related cracks.
Key Advantages:
Lowers concrete pouring temperature to prevent thermal cracking.
Improves concrete quality and durability.
Reduces reliance on traditional cooling equipment, saving costs.
Eco-friendly method that leverages the physical properties of water and ice.
A complete and efficient concrete cooling system is typically composed of the following integrated modules, designed to maintain optimal concrete temperature during mixing and pouring:
water chiller
Utilizes industrial water chillers to cool mixing water down to 1–5°C. It is the most basic and commonly used pre-cooling method.
Produces flake ice or tube ice to directly lower the concrete temperature. Flake Ice : Fast cooling and rapid melting — ideal for large surface area cooling. Tube Ice : Slower melting — suitable for long-lasting cooling effect.
Stores the produced ice in a well-insulated ice storage bin. Transfers ice to the mixing station through screw conveyors, belt conveyors, or pneumatic systems.
