Injecting liquid nitrogen into concrete allows you to cool it down to the optimal pouring temperature in a precise, uniform and often more cost-effective way, especially in hot weather conditions. When added to the high-strength concrete used for pouring foundations and constructing major infrastructures, liquid nitrogen preserves its qualities during curing.
As part of the construction of bridges, dams, highways or any engineered structures, builders can use Air Liquide’s custom concrete cooling solution with liquid nitrogen, CryoCrete™. This application allows builders to accurately adjust the concrete’s temperature, while providing superior and faster cooling compared to ice or refrigerated water.
In order to inject liquid nitrogen into concrete mixers, the CryoCrete™ solution requires the installation of a liquid nitrogen tank, with a pressure-regulating device, a portal equipped with a liquid nitrogen injection lance, and appropriate controls to ensure safe and efficient operation.
Experts from Air Liquide then verify that the application is working properly and train the customer’s employees on how to use the equipment.
In addition to cooling concrete, nitrogen, as an inert gas making up 78% of the volume of the air we breathe, can be used for many applications, such as:
