It seems inappropriate to single out the Los Angeles 6th St Viaduct as an example, unless you intend to comprehensively list the many thousands of US structures affected by ASR. An better alternative would be to provide an anonymous picture of typical ASR attack. . . . LinguisticDemographer 14:13, 11 August 2007 (UTC)
I think that Alkali Silica Reaction and Alkali-aggregate reaction are essentially the same thing and propose that the latter be merged and changed to a redirect to here. – Moondyne 01:57, 9 December 2008 (UTC) Not true.. ACR and ASR are branches of AAR —Preceding unsigned comment added by 142.151.178.65 ( talk) 02:39, 14 December 2008 (UTC)
They are not the same thing. Alkali-aggregate reaction is the umbrella term for a few types of reaction. So should not merge. —Preceding unsigned comment added by 82.38.179.224 ( talk) 17:28, 17 January 2009 (UTC)
I agree that the two should be merged. However, the final article should be Alkali Aggregate Reaction, with Alkali Silica Reaction being a sub-heading, along with Alkali Carbonate Reaction and Alkali Silicate Reaction, etc. All should redirect to AAR. This is how they are conceived and discussed in the Civil Engineering community. Garbagemania ( talk) 02:31, 30 January 2009 (UTC)
I agree with the immediate above. Alkali-Silica, Alkali-Silicate and Alkali-Carbonate Reactions are all sub-headings for Alkali Aggregate Reactions and each should be discussed under a unified AAR heading —Preceding unsigned comment added by 57.66.53.93 ( talk) 14:22, 11 March 2009 (UTC)
Editors and experts . . . I feel like the first few lines of an article should give a clear and concise definition of the topic. As such, I'm wanting to edit the first line to be more like this:
Alkali-Silica Reaction (ASR) is a reaction which occurs in portland cement concrete between reactive (amorphous) silica (in concrete aggregates) and an alkali (usually present in the cement), which results in the formation of a gel.
Would these edits be wrong? Am I making it too specific/exclusive?
Please advise. Thanks. Garbagemania ( talk) 03:40, 30 January 2009 (UTC)
Since the first publication on ASR by Stanton (1940), 83–84 years ago, a so huge amount of papers has been published in the literature that it is a superhuman task to read only a fraction of them and to make a good synthesis of the most relevant. Readers are overwhelmed by the avalanche of information available on the subject and are often drown in the sea of publications.
How to adequately sort this huge mass of information to only extract the most relevant and appropriate one? How to search literature in the most effectively way? According to the impact factors of journals or popularity ranking index in a Google scolar search? According to the h-index of authors to attempt to assess their citation impact? Or by mainly referring to state-of-the art books and up-to-date review works as advised by Wikipedia policy? An excellent discernment is definitely required to properly cite the main conclusions and outcomes of the best works and to give proper credit to the true discoverers while in particular avoiding works simply repeated every decade without added value. It would be useful to gather and to centrally maintain up to date a limited list of mandatory references and list of essential books and review works while avoiding useless inflation. The aim being, of course, to guide the reader and to provide him with a clear vision to try to better understand a very complex system. Shinkolobwe ( talk) 13:48, 28 April 2020 (UTC)
Another source of invaluable information is also the long series (since 48–49 years) of ICAAR Conferences. Shinkolobwe ( talk) 15:51, 28 April 2020 (UTC).

The following 15 editions of ICAAR have taken place: Copenhagen (Denmark), 1974; Reykjavik (Iceland), 1975; London (United Kingdom), 1976; Purdue (USA), 1978; Cape Town (South Africa), 1981; Copenhagen (Denmark), 1983; Ottawa (Canada), 1986; Kyoto (Japan), 1989; London (United Kingdom), 1992; Melbourne (Australia), 1996; Montreal (Canada), 2000; Beijing (China), 2004; Trondheim (Norway), 2008; Austin (USA), 2012; São Paulo (Brazil), 2016; and, Lisboa (Portugal), 2020.

It would be useful to develop the following aspects:
Effect of deicing salts (NaCl) on alkali-silica reaction. It is observed that deicing salts increase the sensitivity of silicate minerals to ASR, but the reason is less well known and several mechanisms could play a role:

In advance, thank you for developing some aspects your are familiar with and adding relevant references and supporting didactic materials (photographs, technical diagrams, figures, tables, ...). Shinkolobwe ( talk) 14:37, 28 April 2020 (UTC)
Most sources outside wikipedia describe "Concrete Cancer" as corrosion of steel reinforcement, not ASR. At best there are different types of "concrete cancer"; perhaps the term is used to describe different phenomena in different parts of the world. At worst, this page is simply wrong.
I believe redirecting "Concrete Cancer" to this page is a mistake. Pjaymes ( talk) 14:39, 5 September 2023 (UTC)
