Ancient Roman Concrete Stands the Test of Time

[Disir]

Roman structures still stand—buildings, bridges, arches, roads, piers, and breakwaters—thanks in large part to the concrete and mortar that the Roman engineers designed. Amazingly, even in corrosive saltwater environments, Roman concrete harbor structures have remained strong and intact for more than 2,000 years.

Romans made concrete by combining lime with volcanic ash to make a mortar and then mixing in fragments of volcanic rock (the aggregate). This material was used to build many impressive structures, including the Pantheon and Trajan’s Markets in Rome, as well as large-scale piers and breakwaters along the coastline designed to protect busy shipping harbors.

Ok, this is what we need to use and stop playing around.

thanks , hard to believe that it hasn't been analyzed and copied if its that much better Desir !!

Roman concrete lacked metal reinforcement for tining....

 

[fncceo]

Roman concrete was laid without reinforcing steel rods. The rods used to strengthen modern concrete structures expand and contact with heat and cold, creating gaps for water to seep in and rust the rods.

Because of the reinforcing rods, the concrete structures can be much thinner than their Roman counterparts.

These two factors mean that modern concrete structures are stronger and lighter than their Roman equivalents, but it also means they wear out much more quickly. Life spans in decades or centuries, as compared to millennia.

Are you a mortarforker also?

If it's late Saturday night and I've had too much ecstasy ... yea.

Oh, I am way too much of a penny pincher to shell out that much dough for a ride...

Amazingly, even in corrosive saltwater environments, Roman concrete harbor structures have remained strong and intact for more than 2,000 years.

Plus inventing "self healing" concrete.

The concrete we use today also keeps getting stronger over time when it is underwater.

Us cement masons call that hydration.
