Recommendation of RILEM TC 258-AAA: RILEM AAR-0 outline guide to the use of RILEM methods in the assessment of the alkali-reactivity potential of concrete

This outline guide, RILEM AAR-0, describes how to use the following test methods in the assessment of the alkali reactivity potential of aggregates and concrete. The test methods included are: AAR-1.1 Petrographic examination method (2016) AAR-1.2 Recommended guidance (Atlas) (2016) AAR-2 Accelerated mortar-bar method (2016) AAR-3.1 & AAR-3.2 Concrete prism test-38 degrees C (2016) AAR-4.1 Concrete prism test-60 degrees C (2016) AAR-5 Screening test for carbonate aggregates (2016) AAR-8 Determination of alkalis releasable by aggregates in concrete (2021) AAR-10.1 & 10.2 Concrete prism test-38 degrees C (2021) AAR-11.1, 11.2 & 11.3 Concrete prisms test-60 degrees C test method (2021) AAR-12.1, 12.2 & 12.3 Concrete prisms-60 degrees C test method with alkali supply (2021) AAR-13 Application of alkali-wrapping for concrete prism testing (2021) This recommendation has been prepared by a working group within RILEM TC 258-AAA. The recommendation has been reviewed and approved by all members of the TC.
