Abstract This Draft for Development describes 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 should not be considered to be a performance test for concrete. NOTE. Aggregates are usually tested in the combination to be used on the job. However, when the aggregate combination to be used is not decided, 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 pessimumvalue which it may possess.
