Talk:Roller-compacted concrete

Heppner Dam

I am removing this text from the article because it has nothing to do with the subject. It belongs in an article about Heppner Dam, if anyone cares to create it:

. Concern over the dam's safety has continued, especially as Heppner had already suffered a dam collapse and fatal flooding with over 200 deaths in 1903. Within a few years of construction, problems were noted with stratification of the water and anoxic decomposition producing hydrogen sulfide. Concerns were expressed that this could in turn give rise to sulfuric acid, and thus damage to the concrete. Controversy continued for some years and the handling of the problem itself has been criticised. In 2004 an aeration plant was installed to address the root cause, as had been called for 18 years earlier.<ref name="Am Sci, Reliably Safe" />

As the refs make clear, this concern about a dam failure is laid at the feet of the RCC technique in particular, not just this one dam. That's a serious issue, and it questions the safety of RCC used for any dam. Andy Dingley (talk) 07:16, 10 July 2009 (UTC)

Road construction?

This article could use some expansion with information about RCC use in road construction. Most web sources seem to be coming from equipment builders/industry advocate groups. --Theodore Kloba (talk) 19:01, 17 April 2015 (UTC)

Good reference article, but not connected to present footnote

I looked up this article because roller-compacted concrete will be used in major repair work at the Oroville Dam. These comments are on the 12/27/16 version of this article.

This article cites the following:

• Abdo, Fares (2008). "RCC Trends in Early 21st Century Medium-Size Dams" (PDF). HydroVision 2008. HCI Publications (240): 1.

This looked like an interesting paper. With a bit of digging, I found the following related paper:

• Abdo, Fares (Nov. 1, 2008). Roller-Compacted-Concrete Dams: Design and Construction Trends
  

at this working URL:
http://www.hydroworld.com/articles/hr/print/volume-27/issue-7/technical-articles/roller-compacted-concrete-dams-design-and-construction-trends.html

If I were to guess, the first paper by Abdo was for a conference; the second is a more refined version for more formal publication. However, the second version doesn't refer to the early Alpe Gera Dam. So, I have removed the reference (has been ref. 3) where Abdo is cited re Alpe Gera; and added Abdo's second paper to the Further reading section. If someone wants to edit further, please do.

By the way, due to the importance of the Oroville Dam situation, Wikipedia's coverage of roller-compacted concrete should no longer be rated "low importance." Oaklandguy (talk) 01:28, 17 April 2017 (UTC)
