Explanation:
Detailed explanation-1: -The Ancient Roman’s concrete consisted of a mix of volcanic ash or also known as Pozzolana, lime, and water to make a mortar [13].
Detailed explanation-2: -Romans made concrete by mixing volcanic ash with lime and seawater to make a mortar, and then incorporating into that mortar chunks of volcanic rock, the “aggregate” in the concrete.
