Let’s start with some basics, concrete versus cement. The two terms are often used interchangeably, but they shouldn’t be – and they are definitely NOT the same thing.
Cement is a powder made from limestone and clay, used as a binder. Concrete is a mixture of cement, water, sand, and aggregates such as gravel, forming a strong construction material. In short, cement is a key ingredient in concrete.
Concrete is a key ingredient in the construction of a new lock chamber at Montgomery Locks and Dam on the Ohio River.
