Chemistry KS3 & GCSE: How the Romans invented concrete
Mark Miodownik explores how the Romans produced the first concrete.
He works with science historian, Chris Brandon, to recreate the way Romans made concrete using volcanic ash, quicklime and water.
Microscopy and animations are used to explain the structure and properties of concrete, and the chemical changes that take place.
