Alkali-silica Reaction and Alkali-carbonate Reaction

Tang Mingshu

Strategic Study of CAE 2000, Volume 2, Issue 1,   Pages 34-40

Abstract:

Alkali-aggregate reaction (AAR) may be divided into two kinds： alkali-silica reaction (ASR) and alkali-carbonatereaction (ACR).The chemical reaction between the reactive aggregate and alkali causes serious expansion and resultsFor ASR, the prime essential is the crystallinity of silica, which causes the rocks to display alkali. display high alkali reactivity.

Multiscale Homogenization Analysis of Alkali–Silica Reaction (ASR) Effect in Concrete Article

Roozbeh Rezakhani, Mohammed Alnaggar, Gianluca Cusatis

Engineering 2019, Volume 5, Issue 6,   Pages 1139-1154 doi: 10.1016/j.eng.2019.02.007

Abstract:

The alkali–silica reaction (ASR) is one of the major long-term deterioration mechanisms occurringASR is a chemical reaction between the silica existing inside the aggregate pieces and the alkali ionsThis chemical reaction produces ASR gel, which imbibes additional water, leading to gel swelling.and validated the resulting model, entitled ASR-LDPM, against several experimental data sets., while ASR-LDPM is utilized as the mesoscale model.
