ASR is the most common form of alkali-aggregate reaction (AAR) in concrete; the other, much less common, form is alkali-carbonate reaction (ACR). ASR and ACR are therefore both subsets of AAR. ASR is caused by a reaction between the hydroxyl ions in the alkaline cement pore solution in ...
In regions of the world with reactive aggregate, Alkali-Silica Reaction (ASR) is a relentless infrastructure assassin. If the seeds of ASR—reactive aggregate and Portland cement spawned calcium hydroxide—are present in cured concrete, that concrete structure will not survive to the end of its en...

This work involves research on the use of fly ash to mitigate alkali-silica reaction (ASR) in concrete made with recycled concrete aggregate (RCA) that comes from concrete with a known ASR history. Modified ASTM C 1260 and C 1567 with different aggregate grading showed that a 25% cement sub...

The main feature of this reaction is the creation of a hydrophobic expansive gel which causes internal damage in the concrete. This damage is strongly related to the macroscopic stress state. Vice versa, the caused damage can have macroscopic consequences. Therefore a structural model should be ...
Numerous reinforced concrete structures in Denmark may potentially suffer from severe alkalisilica reaction (ASR) and some are already severely damaged. However, the influence of drilling and crack orientation on material properties of concrete cores drilled out from actual severely damaged structures is ...
Cracks and damage to the part of the concrete structure are the results of the formation of this expansive gel. There are several ways to minimize this reaction, out of which Lithium Nitrate compound is believed to reduce the reaction between alkalis (present in the cement) and silica (...
