Concrete cooling with liquid nitrogen using Air Liquide’s injection lance technology
See Air Liquide Group's complete offering in Glass, Cement & Lime.
Air Liquide's concrete cooling technology, CryoCrete™, is the ideal solution for handling the most demanding cooling requirements and pour temperature specifications for your concrete during extremely hot weather conditions. Mass pour jobs in need of concrete cooling, such as caps and columns, bridge decks and power plants have all been poured using CryoCrete.
Air Liquide was involved at the very foundation of building the largest and most visible public works project that Northern California has seen in decades—the San Francisco-Oakland Bay Bridge. With Air Liquide CryoCrete™ liquid nitrogen, the bridge’s foundation of steel and reinforced concrete was chilled to the optimum temperature for pouring.
The 40-hour pour utilized some 550 loads of concrete and 60,000 gallons of liquid nitrogen, which was injected into individual concrete loads at an Air Liquide injection staging area under the Bay Bridge in the middle of San Francisco Bay. This process assured that each shipment of concrete would be individually checked to affirm that it was delivered at the optimum pouring temperature to meet construction standards of the successful project.
