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-carbonateThe chemical reaction between the reactive aggregate and alkali causes serious expansion and resultsin the deterioration of concrete structure, which is the common character of both.For ASR, the prime essential is the crystallinity of silica, which causes the rocks to display alkalicryptocrystalline, microcrystalline, glassy and strained silica, cristobalite, tridymite, etc. display high alkali
