Alkali-Silica Testing, Alkali-Silica Reactivity
Alkali-silica reactivity, a major cause of deterioration in concrete, is explained in the introduction to this video. Determination of reactivity damage through use of a handbook, and prevention through use of low-alkali cements and aggregates and pozzolanic materials are discussed. New tests are explained in detail: a gel recognition test for use by field personnel, and a laboratory procedure, ASTM P 214. Conventional laboratory test methods, ASTM C 227 and ASTM C 289, are also demonstrated. SHRP tape 29.
