ABSTRACT
USA had cracked as a consequence of alkali-silica reaction (ASR). Because of the USA experience, the UK Building Research Establishment decided, in 1946, to carry out a program of work to establish whether any British aggregate might be expansively reactive with the alkalis released by a Portland cement. Ihe investigations were continued until 1958 and a series of papers published[l]. The authors concluded that UK aggregates were unlikely to be expansively reactive with high alkali cements at normal temperatures.
