History Channel Modern Marvels - Concrete VHS

This is the definitive chronicle of the substance that changed the world. It is literally the building block of civilization. Without concrete, life as we know it would not exist--our cities, roads and epic public works would not be the same, our way of life likely impossible. So ubiquitous as to be largely ignored, concrete nonetheless has a story that symbolizes the greatest advances and towering failures of mankind. MODERN MARVELS mixes up a fascinating blend of history, engineering and cultural observation to tell the story of CONCRETE.
