What is Cement?

What is Cement?

Cement and concrete are not quite the same thing, although the terms are often confused. Cement is actually one of the main ingredients needed to make concrete.

Cement serves as the binder that allows water and aggregate material (such as crushed rock or gravel) harden into concrete. It is made of a number of different powdered minerals. When cement is mixed with water, a chemical reaction called hydration occurs, allowing the paste-like substance to harden into solid concrete.

What's in cement?

Cement may include a number of different minerals, including:

- Limestone
- Calcium
- Aluminum
- Slate
- Shale
- Sand
- Iron

Types of Cement

There are two types of cement: hydraulic and non-hydraulic.

1.) Hydraulic cements can harden in wet conditions. The cement will dry and cure regardless of the weather and climate. Hydraulic cement can even harden under water.

2.) Non-hydraulic cements will only harden in a dry environment. These cements are typically more affordable, but they have longer drying times and they take longer to reach their full strength.
