Use of Water Chiller Unit and Ice Cold Water System in Batching Plants for Concrete Cooling

Concrete Average Temperature

Measurement of fresh concrete temperature and moisture content of concrete is extremely important. The average temperature of concrete is calculated by taking into account the heat loads and mixing ratios of the substances in the concrete mixture. There is another important point here. That is the exothermic reaction that occurs when cement and water meet. As a result of this exothermic reaction, a great deal of heat is released. In order to remove this heat, other materials added to the mixture must be cooled.

If this heat is not removed, plastic shrinkage in concrete is inevitable. To give some examples; a decrease in the moisture content from 90% to 10% increases the amount of evaporation approximately 8 times, and a decrease to 50% increases it 5 times. The change in wind speed also has a significant effect. For example, when the wind speed increases from 0 km/h to 40 km/h, the evaporation rate increases by 9 times, and if it increases to 6 km/h, it increases the evaporation rate by approximately 4 times.

Air temperature is also very important here. In weather conditions where the air temperature exceeds 30°C for 3 consecutive days, it is recommended not to pour concrete during the day. Assuming that the air temperature increases from 10°C to 38°C, the evaporation rate can increase approximately 7 times, and when it increases to 21°C, the evaporation rate can increase 2 times.

There are different alternatives for cooling concrete. The main point here is the temperature value at the end of the mixture and the target temperature value.

Depending on the target temperature value, solutions such as aggregate cooling, water cooling and concrete cooling by adding ice can be used.

Water cooling is the first step and the most economical solution in concrete cooling. Evanso offers you suitable alternatives in this field with its various product groups.
