The apparent differences in the autoclaved concrete industries in the Soviet Union and the United States are attributed to the different needs, raw material availabilities and end usage in the two countries. Drying and cracking of concrete masonry gave impetus to autoclave curing in the United States to alleviate the problem. In the Soviet Union, shortage of cement and abundance of calcareous and siliceous materials, and urgent need of housing were factors leading to high pressure steam curing on a big scale. The most important property after strength in the Soviet Union is resistance to frost deterioration and, in the United States, to shrinkage cracking. The Soviets are highly research orientated with considerable emphasis on fundementals.
