CryoCrete suits the most demanding cooling requirements and pour temperature specifications for concrete during extremely hot weather conditions, notes developer Air Liquide. The manufacturer’s system injects liquid nitrogen into individual concrete loads, providing what product engineers contend is flexible and accurate temperature adjustment with greater and more rapid cooling than ice or chilled water. The process assures each load of concrete is delivered at the optimum pouring temperature to meet construction standards. 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 Industrial U.S. LP, 877/855-9533; www.us.airliquide.com
