Expansion of concrete due to reaction between andesitic aggregate and cement
Recent work has shown that certain types of rock used as aggregate react chemically with high alkali cement; this reaction causes excessive expansion and in few cases ultimate failure of concrete; one of products of reaction filters through concrete and exudes on surface; possible means of detecting troublesome rocks involves use of ultraviolet light and selective staining methods.
