Characteristic crack pattern associated with the alkali–silica reaction affecting a concrete step barrier on a US highway. Note the typical fatty aspect of the silicagel exudations imbibing the concrete surface along the two sides of the cracks.
Typical crack pattern of the alkali-silica reaction (ASR). The gel exudations through the concrete cracks have a characteristic yellow color and a high pH. The fatty aspect of the exudations imbibing the concrete porosity along the cracks is also a distinctive feature of ASR.
