Development of a Field Exposure Site for Predicting and Mitigating ASR Damage

Alkali-silica reaction (ASR) is an expansive reaction between the alkalis in the cement and reactive silica in the aggregates. Arkansas is currently witnessing the detrimental effects of ASR at various locations in Arkansas. A petrographic analysis of samples from select locations has confirmed that ASR is present in these areas. Therefore, prevention and mitigation measures must be developed. There has been a significant amount of research conducted using accelerated mortar bar tests (ASTM C1260 and AASHTO T303) and concrete prism tests (ASTM C1293) to determine if specific concrete mixtures show potential for alkali-silica reactivity. The ASTM C1293 test is the preferred method of assessment in laboratories because it best represents field conditions. More recently, however, outdoor field exposure sites have become popular methods of predicting ASR damage. These sites represent field conditions much better than ASTM C1293 and thus become better predictors for finding reactive aggregates.
