How Has Roman Concrete Lasted for Millennia? 1,900-Year-Old Latrine Offers Clues

What commenters are saying

Commenters debated whether modern concrete could match Roman durability. Many argued that modern steel rebar corrodes unless fully encased, but alternatives like stainless steel or coated rebar exist. Some noted that modern infrastructure is built to a cost, not for eternity, and that functional obsolescence often makes extreme longevity wasteful. Others pointed out that Roman concrete was not inherently better, just optimized for different goals. A few highlighted the Practical Engineering video debunking the myth that Roman concrete was superior.
