Behavior of Self-Consolidating Concreteat Cryogenic Temperatures

The Euclid Chemical Company, Cleveland, Ohio, 44110, USA

Self-consolidating concrete (SCC) was recommended in an effort to speed up placement during the construction of a liquefied natural gas (LNG) containment tank in Freeport, Texas. Liquefying gases to cryogenic temperatures is widely used to reduce their volume, and there fore making their transportation over long distances more economical. The behavior of ordinary concrete exposed to very low temperature is somewhat documented, but because the composition of a self-consolidating concrete (SCC) slightly differs from that of an ordinary con crete, the design/engineering group wanted some assurance that an SCC mix would present similar properties than those found for ordinary concrete.
