Cooling Concrete with Liquid Nitrogen Concrete ...

01/05/1983  An alternative to ice for providing necessary cooling is to use liquid nitrogen (LIN), an inert liquid with a temperature of -320 degrees F. LIN is delivered to the batch plant and is stored on site/used as needed. LIN can be used to cool the batch water, produce an ice-and-water slush mixture, and/or cool the cement.

Liquid Nitrogen for Concrete Cooling

01/09/2004  Abundant and generally inexpensive, liquid nitrogen (LN) is gaining popularity across the nation as a substitute for costly water chillers, additives, and/or cumbersome ice bags. Until recently, safety concerns and lack of understanding slowed any widespread use of LN by the concrete industry. This article describes the successful use of LN to cool concrete by the Texas Department of ...

Effects of Liquid Nitrogen Cooling on Fresh Concrete ...

01/03/2010  In hot weather, it is a common practice to cool concrete - particularly for mass concrete applications - to prevent thermal cracking and durability problems. An increasingly popular method of cooling is through direct injection of liquid nitrogen (LN2) into the drums of concrete trucks. During an investigation of the effects of LN2 on concrete properties, it was observed that the practice has ...

Liquid Nitrogen-Cooled Diamond-Wire Concrete Cutting

Liquid Nitrogen-Cooled Diamond-Wire Concrete Cutter can be used to cut through thick concrete walls, floors, and structures without using water to cool the cutting wire. The diamond wire is cooled with liquid nitrogen in a 0.9 m (3 ft.) long by 7.6 cm (3in.) diameter pipe housing. The nitrogen evaporates, so no contaminated liquid waste is generated. Other than the liquid nitrogen, the system ...
