How did the Romans come up with the name concrete?

The term "concrete" is derived from the Latin Word "concretus," which means "to grow together" or "to harden." The Romans used this term to describe their building material, which was a mixture of lime mortar, water, sand, and aggregates, that would harden over time. This innovative material allowed them to create durable structures, such as aqueducts and amphitheaters, that have withstood the test of time. The use of the Word reflects the Romans' understanding of the material's properties and its transformative nature in construction.
