ASR Prevention in DOD

Supplementary cementitious materials (SCM) are used in concrete to prevent alkali silica reactivity (ASR) in Department of Defense (DOD) concrete construction. To insure that deleterious expansion does not take place, the DOD specifications rely primarily on ASTM C 1260 and C 1567. For airfield pavements, the threshold expansion indicative of ASR potential was conservatively set to 0.08% after 28 days of exposure. In this paper, the rationale for the reliance on these tests is explained, as well as the choice for the threshold expansion. The approach for ASR prevention, currently being expanded to all concrete construction, is also detailed.
