Answer 1

The Romans perfected concrete by adding volcanic aggregate, making it stronger and more durable.

Step-by-step explanation:

The Romans perfected concrete when they discovered that pouring volcanic aggregate into the mixture made it stronger and more durable. This volcanic aggregate, called pozzolana, reacted with the lime in the mixture to form a calcium silicate hydrate, creating a sturdy material that was resistant to weathering. The Romans used this improved concrete to construct remarkable structures such as the Pantheon and aqueducts which have stood the test of time.
