AbstractCertain siliceous and sedimentary rocks in Nova Scotia, when used as aggregate with high alkali cement, have produced excessive expansion of concrete. Laboratory studies showed a type of alkali-aggregate reaction to be responsible. Rock types in structures and in aggregate sources were identified by petrographic examination, the main types being selected for study of alkali-reactivity.
