Secrets of Roman Concrete Revealed




Anybody that's walked past a crumbling concrete structure and then seen pictures of ancient Roman facilities made of ... wait for it... concrete, wonders why modern concrete fails while Roman concrete keeps going like the energizer bunny.  The article excerpted and linked below provides some answers.

The secret to Roman concrete lies in its unique mineral formulation and production technique. As the researchers explain in a press release outlining their findings, “The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated—incorporating water molecules into its structure—and reacted with the ash to cement the whole mixture together.”


Looking forward to seeing these ancient methods combined with modern solutions.
