Is cement solid or liquid

Cement starts off in a semi-liquid state that has the ability to flow. After a while, the cement will cure and harden into a solid. Whether the solit cement is a fluid depends on the kind of cement and how much, as even cement can change shape very slightly. As an example, people who study fluid dynamics also study the movement of the continents and how they interact with one another. Solid rock has the ability to compress and decompress rapidly, causing earthquakes. When dealing with a large quantity of cement, there is an element of fluidity involved.
