In The traditional Egyptian and later on Roman eras, builders found out that adding volcanic ash to lime allowed the combo to set underwater. They discovered the pozzolanic reaction.[sixteen]
Reduced temperatures also adversely have an effect on its toughness. To compensate for this, an additive such as calcium click here chloride is combined in with the cement.
