A Study into the Alkali-Silica Reactivity of Recycled Concrete Aggregates and the Role of the Extent of Damage in the Source Structures: Evaluation, Accelerated Testing, and Preventive Measures

The paper covers the expansion of concrete containing recycled concrete aggregates produced from concrete affected by  alkali-silica reaction.  The  accelerated mortar test  bar test , and the Concrete Micro Bar Test used with suggested expansion limits at 28 and 56 days were found effective in predicting the expansion of concrete prisms at one or two years for samples with and without preventive measures.
