my understanding is that the romans made some contributions to the
development of concrete. They, by no means, 'invented" the idea of
reinforced building materials----- the idea evolved over millennia
They developed a hydraulic concrete that could be used underwater, for their ports, and refined other types. They were excellent organizers and at engineering and copying others designs and tweaking them as need arose. Their first run-ins with the Carthaginians resulted in their become good shipbuilders almost overnight and building a large navy in a short time. Romans were defeated many times, but they were tenacious bulldogs and learned from mistakes quickly. They went into decline when their birthrates in the 'home regions' fell off, their economy became based on buying luxury imports for the wealthy and hemorrhaged, and they had to rely more and more on 'barbarian' mercenaries, a familiar pattern historically, not just for Rome.
yes---the ROMANS DID adopt the technology of the peoples they conqured and
enslaved------
As actual INNOVATORS----nope---not much-----they built an empire based on conquest and chattel slavery and barbarism-------and developed the legal code that
their true son ADOLF HITLER aped
----every society is right now and then---
the US slave system of the southern cotton industry -----SPAWNED THE COTTON
GIN<<<< a very important innovation. The US slave system also spawned the
Civil War and its filth still infiltrates all of USA society and-----to some extent----THE
WORLD
