We deserve better, as a people, than to be surrounded by so many spanking new ruins.

Our interstate bridges last only a few decades before they plunge into the river. Ditto highways. The Pantheon in Rome is an immense 130-140' wide dome over 2000 years old which still stands. The first concrete highway somewhere in New England is still in use and was built in the 1890's. The main reason our concrete fails is the rebar which corrodes in the alkaline concrete and swells, spalling the concrete and leading to premature failure. Now new rebars are being used like "greenbar" which is just epoxy painted rebar which may work a lot better as well as new alloy rebars like aluminum bronze which may last forever. The Pantheon is still there because it is unreinforced as is the highway in NE.sv kohohttps://www.blogger.com/profile/11058401490041584973noreply@blogger.comtag:blogger.com,1999:blog-5811749743523633503.post-88549639742856474712014-01-20T05:39:44.801+00:002014-01-20T05:39:44.801+00:00I've seen it done, exatly as you describe on t...I've seen it done, exatly as you describe on the English documentary series Edwardian Farm. They loaded a small kiln with coal and limestone, dug out the quicklime in as much cover as they could find, drew it by horse and cart to the farm, dumped it out as you said and only just beat the rain. It's a fascinating show and a fascinating industry.<br />Thanks for sharing.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5811749743523633503.post-47890090999749936162014-01-18T02:58:41.871+00:002014-01-18T02:58:41.871+00:00Fascinating.
