Expansion of Concrete Due to Alkali-Silica Reaction

The literature dealing with the expansion of concrete due to alkali-silica reaction (ASR) is reviewed and experimental work currently in progress at the Cement & Concrete Association is described. 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/m3.
