USE OF DYNAMIC NONDESTRUCTIVE TEST METHODS TO MONITOR CONCRETE DETERIORATION DUE TO ALKALI-SILICA REACTION

Dynamic nondestructive tests such as pulse velocity and dynamic modulus to monitor the initiation and progress of concrete deterioration due to alkali silica reactions (ASR) are reviewed. The study found that both pulse velocity and dynamic modulus are sensitive to material and structural changes arising from ASR and that they can respond reliably to changes prior to first crack, at first crack, and the progress of deterioration with time in concrete both with and without cementitious materials other than portland cement. It is noted, that with good engineering judgments, pulse velocity measurements can be used to assess structural deterioration due to ASR.
