Summary:

Accurate, reliable, and timely laboratory assessment of concrete mixtures -- aggregates combined with cementitious materials -- is a critical component in ensuring the durability of concrete infrastructure from the adverse effects of the alkali-silica reaction (ASR). Currently, the "Concrete Prism Test" (ASTM C1293) is the most reliable standard test method for assessing the suitability of materials and materials combinations for resistance to damage by ASR. However, the main drawback of this method is the 1- to 2-year duration required for the test. This research study evaluates a new nonlinear acoustic technique for characterization of ASR damage in standard concrete prism specimens. Nonlinear impact resonance acoustic spectroscopy offers a fast and reliable measurement of the material nonlinearity. Microstructural changes that occur as a result of ASR cause an increase in the measured nonlinearity, which can be used as a measure of the amount of ASR-induced damage. This study evaluates 10 concrete mix designs with varying ASR reactivity. Both standard expansion tests and nonlinearity measurements are performed on the specimens. This report presents the results of those tests to illustrate the utility of the new method as a complementary technique for damage assessment of laboratory concrete prisms specimens.
