That's the way the modern concrete crumbles

Here's yet another interesting piece I found last week while doing the daily news headline roundups from around the Charlotte region for and the UNC Charlotte Urban Institute homepage. (Yes, we read the region's news and link to what's of note in terms of public policy and urban growth topics, so you won't have to. Wonky? Sure, and proud of it!)

The long-lost secret of Roman concrete's endurance: If you have ever seen crumbling concrete and said as I have trudging across the parts of the UNC Charlotte campus dating to the 1960s-1980s (see photo below) "Good grief, I've seen ancient Roman concrete in better shape than this!" the next article will open your eyes. I spotted it on the excellent website, which links to the original article on Bloomberg Businessweek: Ancient Roman concrete is about to revolutionize modern architecture.  The Romans used lime and volcanic rock, and their process produces less carbon dioxide than today's process.
