The primary objectives of the existing standard test methods for evaluating alkali-aggregate reactivity (AAR) in mortars and concrete is to identify the susceptibility of aggregates to undergoing alkali-silica reaction (ASR), to identify the effectiveness of supplementary cementitious materials (SCMs) in mitigating ASR, and quantify the suitable dosage level of SCMs in the concrete mixtures. However, these short-duration tests (the concrete prism test, mortar bar method test, accelerated mortar bar test, new concrete cylinder test, and new autoclave concrete prism test) have limitations in their ability to provide a direct measure of how a job’s concrete mixture might perform in the field over the long term. These sessions will shed light on developments in the areas of new test methods that are focused on assessing the alkali-silica reactivity potential of a job’s concrete mixture and new nondestructive test methods to evaluate the extent of damage in job concrete mixtures. Engineers, contractors, researchers, and students will benefit from learning about the latest research and test methods that will pave the way for a performance-based approach in specifying durability in concrete mixtures.
