ABSTRACT
Kouga Dam has been extensively monitored during and after its completion in 1969. Initially the dam reacted as expected but since 1972, it became clear that some form of SCR (swelling due to a chemical reaction) in the concrete was occurring. (SCR is also generally known as alkali-aggregate reaction (AAR)) In addition to this, some inelastic movement of the right flank foundation followed a few years later that complicated the behaviour model of the structure even further.
