What Is The Difference Between Concrete And Cement?

Cement is made from calcium and silica. You can find limestone, sand, clay, and other natural materials in cement. However, cement is found in concrete. When you also add other materials, like gravel, to make the cement more durable, it is then considered concrete. Cement isn't used very often alone unless on small projects or repairs.

Posttensioned Concrete - Portland Cement Association

The concrete component is cast with steel reinforcing strands installed in a way that protects them from bonding with the concrete. This practice gives designers the flexibility to further optimize material use by creating thinner concrete members. The materials used to post-tension concrete members are ultra-high-strength steel strands and bars.
