Figure 5. Enlarged Photo. Thin-Section Cut of ASR-Damaged Concrete, Showing ASR Gel and Typical Crack Pattern (Through Aggregate and into Surrounding Matrix). This photo shows cement paste, a particle of reactive aggregate (in this case, flint), and a ribbon of reaction product (alkali-silica reaction gel) running through both of them. A crack runs from a point where the gel meets the cement paste and continues parallel to the gel.
