Abstract:
The objective of this research project was to evaluate the potential of the proposed Strategic Highway Research Program (SHRP) rapid immersion test covered by AASHTO TP 14 to determine alkali-silica reactivity (ASR) of Kansas aggregates using concrete beam samples. The TP 14 standard provides a proposed standard test method for accelerated detection of potentially deleterious expansion of mortar bars due to alkali-silica reaction. The mortar bars are cast and cured and the length measured as specified in the test procedure. The difference between the initial length of the specimen (at 24 hours after casting) and the length at each time period of measurement is calculated and expressed as the expansion in percent (of the original length).
