What's the Difference Between Cement and Concrete?

The paste, composed of cement and water, coats the surface of the fine (sand) and coarse aggregates (rocks) and binds them together into a rock-like mass known as concrete. Within this process lies the key to a remarkable trait of concrete: it's plastic and can be molded or formed into any shape when newly mixed, strong and durable when hardened.

Clinker (cement) - Wikipedia

Upon treatment with water, clinker reacts to form a hydrate called cement paste. Upon standing the paste polymerizes as indicated by its hardening. Contribution to global warming. As of 2018, cement production contributed about 8% of all carbon emissions worldwide, contributing substantially to global warming. Most of those emissions were produced in the clinker manufacturing process.
