>the 50 gigapascals of pressure that one would find in the base of a skyscraper. I guess you will need to rethink about the order or magnitude of the pressure you cited: https://en.wikipedia.org/wiki/Orders_of_magnitude_(pressure) https://en.wikipedia.org/wiki/Orders_of_magnitude_(pressure) Easy comparison terms are pressure to create artificial diamonds 18 GPa, pressure at the bottom of the Mariana Trench 110 MPa. Compression resistance of concrete is between 20 and 80 MPa: https://en.wikipedia.org/wiki/Compressive_strength https://en.wikipedia.org/wiki/Compressive_strength Where 20 is "common" concrete, 30-50 is typical reinforced concrete, anything above is specisl, high strength concrete.
