Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, your addition of one or more external links to the page Concrete recycling has been reverted. Your edit here to Concrete recycling was reverted by an automated bot that attempts to remove links in references which are discouraged per our reliable sources guideline. The reference(s) you added or changed (https://www.rroij.com/open-access/effect-of-recycled-coarse-aggregate-onconcrete-properties.php?aid=50136) is/are on my list of links to remove and probably shouldn't be included in Wikipedia. If you were trying to insert an external link that does comply with our policies and guidelines, then please accept my creator's apologies and feel free to undo the bot's revert. However, if the link does not comply with our policies and guidelines, but your edit included other, constructive, changes to the article, feel free to make those changes again without re-adding the link. Please read Wikipedia's external links guideline for more information, and consult my list of frequently-reverted sites. For more information about me, see my FAQ page. Thanks! --XLinkBot (talk) 03:10, 5 May 2017 (UTC)
