Roman Concrete

Aqueduct in Segovia

Alcántara Bridge in Cáceres

Talking Point for Sept 20th 2017

According to the links Audrey sent us there is great interest in discovering the exact composition of Roman concrete as, believe it or not, that knowledge has disappeared. Time has shown that Roman concrete sets hard under water and its durability surpasses modern day concrete.
Spain has a fine legacy to prove the point.
An important ingredient was volcanic ash and Rome had plenty of that.

Compare with the Kingdome stadium in Seattle, a concrete building which was demolished by implosion after only thirty years, It had outlived its use they said.

Come to our talks and tell us about the Roman structures you have visited and how well they stand the test of time.

Be prepared!

Write to us at  asedow@gmail.com  for the links where you can watch the demolition of the stadium and read about the durability of Roman concrete.
