This involves a reinforced concrete beam manufactured in 1970 which was strengthened with a steel plate bonded to its underside and has since been subjected to a permanent load of just over six tons.  &#8220;After 50 years under 87 percent of the average breaking load, the epoxy resin bonding shows no weaknesses. Bonded steel plate reinforcements have thus passed the long-term test,&#8221; says engineer Christoph Czaderski, who has supervised the test in recent years.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-12-long-term-bonded-steel-concrete-50th.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Long-term study of bonded steel reinforcements on a concrete beam enters 50th year<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For half a century now, a long-term experiment has been running in Empa&#8217;s largest testing laboratory at the D\u00fcbendorf site.
