In The traditional Egyptian and later on Roman eras, builders learned that including volcanic ash to lime permitted the combination to established underwater. They discovered the pozzolanic reaction.[16]
Next, integral reinforcing steel gives modern concrete assemblies fantastic strength in stress, Whilst Roman concrete could depend only upon the toughness in the concrete bonding to resist stress.[25]
