APPLICATION OF REFERENCE TEST METHODS, OF THE KINETIC TEST AND OF THE PERFORMANCE TEST TO ASSESS ASR

The authors present the methodology developed to examine aggregates used in concrete. This methodology comprises of several steps: 1. Geological survey of the site; 2. Sampling, taken in accordance to the complexity of the deposit; 3. Petrographic and chemical study; 4. Characterization tests; and 5. Preventive measures assessment. In the four examples presented, steps 1, 2 and 3 are compulsory. Step 4 is invoked when the innocuous character of the aggregate is not certain. Step 5 is employed if the aggregate is shown to be deleteriously reactive. (A) For the covering abstract see IRRD 871351.
