Alkali-silica reaction ASR can cause expansion and cracking of concrete due to the reaction between alkalis from the cement i.e. the glue of concrete and reactive silica from aggregate i.e. the sand and gravel. The reaction cannot be stopped once it is initiated. Despite tremendous progress over the past 80 years, a breakthrough of ...+
The names used for minerals and rocks for concrete aggregates in the United States are listed in Appendix 3. Reactive silica in aggregates We saw in Chapter 1 that for the alkali-silica reaction to occur, a reactive aggregate had to be present in the concrete, and that a reactive aggregate was one in which there was reactive silica.+
For alkali-silica reaction to occur, three conditions must be present reactive forms of silica in the aggregate high-alkali pH pore solution sufficient moisture The amount of gel formed in the concrete depends on the amount and type of reactive silica, and the alkali hydroxide concentration in the con-crete pore solution.+
