• Description:
  Alkali-silica reaction (ASR) is recognized as a major concern for the Texas Department of Transportation (TxDOT). In the previous project 0-6656, a volumetric change measuring device (VCMD)–based aggregate chemical method was validated as a rapid (within 5 days) and reliable method to determine aggregate reactivity in terms of measuring composite activation parameter (CAP) and measure aggregate threshold alkalinity (THA). A new accelerated concrete cylinder testing (ACCT) was developed in that project as a potential concrete ASR test.
