Alkali-silica reactionFly ashSlag, petrographyThis paper presents an experimental investigation of the alkali-silica reactivity of alkali-activated concrete (AAC). Some researchers suggest that the high alkalinity of the pore solution could make AAC more susceptible to alkali-silica reaction (ASR) than...

One of the possible applications is utilizing waste glass in concrete; however, alkali–silica reaction (ASR) is of major concern. In this study, tests were conducted by applying three different procedures: ASTM C1293, RILEM AAR-2, and microbar test methods. In microbar testing, glass ...
No. 5 is not only suspicious alkali-silica reactive aggregates, but also suspicious alkali-carbonate reactive aggregates. The conclusions obtained by those three methods are basically consistent. Moreover, the micro mortar bar method is fast. It is much convenient...

Alkali silica reaction (ASR) occurs due to chemical reaction between hydroxyl ions in the pore water within the concrete matrix and certain forms of silica. This reaction could lead to strength loss, cracking, volume expansion and potentially failure of the structure. This manuscript reports findings...
