Block Cracking – Pavement Interactive
Description. Interconnected cracks that divide the pavement up into rectangular pieces. Blocks range in size from approximately 0.1 m 2 (1 ft 2) to 9 m 2 (100 ft 2).Larger blocks are generally classified as longitudinal and transverse cracking. Block cracking normally occurs over a large portion of pavement area but sometimes will occur only in non-traffic areas.

Causes and Remedies of Cracks in Concrete Buildings
9. Movement due to Chemical Reactions. The concrete may crack as a result of expansive reactions between aggregate, which contains active silica, and alkaline derived from cement hydration. The alkali silica reaction results in the formation of swelling gel. This tends to draw water from other portions of concrete.
Alkali-Aggregate Reaction - cement
Alkali-Aggregate Reaction. In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms: alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR).
