High temperature work has always been a hot topic that society usually pays attention to, and with the trend of global warming, people have some ways to lower the temperature. And since 2007, the state has made corresponding high-temperature allowances for workers who work in high-temperature climates and open-air environments. Cement isolation pier is more stringent in terms of temperature, so what are the ways to reduce the high temperature? Then to ensure the continuity of production? Today, Shunfa Cement Prefabrication Factory will give us a brief introduction to help you produce better !

Cooling method one: cooling concrete mixing water

The method of cooling the concrete mixing water is used to reduce the temperature of the concrete up to 6 ℃ to ensure the production of cement products.

Cooling method two: use ice to replace part of the mixing water

We know that ice is a solid state of water. Luoyang Transportation Facilities Factory believes that it is feasible to lower the temperature of concrete through ice, but it is limited by the amount of ice to replace the mixing water.

Cooling method three: cooling the mixed concrete with liquid nitrogen

As we all know, the temperature of liquid nitrogen is very low. Using liquid nitrogen to cool down can make the concrete reach the lowest limit temperature.

Cooling method 4: Cooling of coarse aggregate

What is coarse aggregate cooling? Coarse aggregate cooling is spraying with cold water or flushing with a large amount of water. Coarse aggregate occupies a larger share in the concrete mixing process, so we can lower the temperature of the concrete by reducing the temperature of the coarse aggregate.
