The reaction between the active silica constituents of aggregates and alkalis in cement in the presence of moisture is called Alkali-Silica Reaction (ASR). ASR forms a swelling gel which can expand and cause internal stresses in cementitious materials leading to cracking, loss of strength, and eventually failure. The primary objective of this research study is to evaluate the advantages associated with implementing the new test method AASHTO TP-110 to better characterize the ASR potential of Idaho aggregates. Total of 8 identified aggregate types will be tested. The sources of those aggregate types are across Idaho with different degrees of ASR potential.
