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 be used is not decided, however, the test sample of aggregate is tested in combination with both an inert aggregate and an aggregate geologically similar to itself in proportions specified in the method. This procedure provides a generally satisfactory assessment of the aggregate by accommodating any pessimum value which it may possess.
