If you’ve ever seen the concrete in your house’s foundation or on your sidewalks start to crack and crumble after a few years then you might be interested to know that the answer to this sad situation exists in the 2,000 year old Roman Pantheon.\u00a0 Apparently the Romans were better engineers than we are, at least as far as concrete goes.<\/p>\n

Researchers at MIT have been studying the phenomenal longevity of Roman concrete edifices and they’ve discovered<\/a> that using quick lime instead of slaked lime provides for the more reactive inclusions in the material to actually “self-heal” incipient cracks.<\/p>\n

\u201cThe benefits of hot mixing are twofold,\u201d Masic says. \u201cFirst, when the overall concrete is heated to high temperatures, it allows chemistries that are not possible if you only used slaked lime, producing high-temperature-associated compounds that would not otherwise form. Second, this increased temperature significantly reduces curing and setting times since all the reactions are accelerated, allowing for much faster construction.\u201d<\/strong><\/p>\n

Near the end of the article it’s stated that the researchers plan to commercialize the ancient technique.\u00a0 Well, as a descendant of the Romans, I declare this cultural (or technical) appropriation.\u00a0 And I demand reparations.\u00a0 I’ve estimated my cut as approximately one billion denarii (silver of course).\u00a0 If enough denarii can’t be found I will settle for gold doubloons.<\/p>\n","protected":false},"excerpt":{"rendered":"
