Alkali-silica reaction and its effectes on concrete
- Construction Technology Labs., Inc., Skokie, IL (United States)
Alkali-silica reactivity (ASR) has resulted in cracking of concrete in numerous dams in the United States and elsewhere. Many of these dams were constructed prior to the initial discovery of ASR in California in the late 1930`s, thus no special precautions could have been taken to prevent its development Since that time, ASR has been identified in all types of structures located in many parts of the world. Voluminous research has been carried out to better characterize its development, to more completely understand the mechanisms of expansion and distress, and to design means to mitigate its development in new and existing construction. Based on this work, this paper describes the nature of ASR, its effects on concrete, and means to control its development, with special reference to dams.
