Testing aggregates - Method for determination of alkali-silica reactivity. Concrete prism method Ingestion-build-266356 The manipulation test has been1 Scope This British Standard specifies a method of measuring the expansion of concrete produced by alkali silica reaction involving specific combinations of aggregates. The method is designed as an accelerated laboratory test for a specific combination of aggregates and is not considered to be a performance test for concrete. NOTE Aggregates are usually tested in the same combination as when they are actually used. When the aggregate combination to
