The beginning:
Alkali-Aggregate Reaction in Dams and Concrete Durability
Concrete durability is one of the most important factors influencing the performance of structures.  This is especially true for dams where concrete is affected by a range of environmental stresses.
One phenomenon that can negatively affect concrete durability in dams is alkali-aggregate reactions.  This reaction involves the interactions between the chemicals in concrete and the chemical composition of the surrounding river.  This reaction results in parts of the concrete matrix turning into silica gel that can take up water and swell.  This swelling can cause a range of structural problems including cracking and buckling(
