EXPANSION OF CONCRETE DUE TO ALKALI-SILICA REACTION

An illustrated article reviews literature dealing with the expansion of concrete due to alkali-silica reaction (asr), and describes some current experimental work. It is shown that concrete containing a reactive aggregate and a UK cement is unlikely to exhibit deleterious expansion due to asr if the alkali content of the concrete, expressed as equivalent Na20, is less than 4 kg/cubic metre.
