- A cement is a binder, a substance that sets and hardens and can bind other materials together.
- Cements used in construction can be characterized as being either hydraulic or non-hydraulic, depending upon the ability of the cement to be used in the presence of water (see hydraulic and non-hydraulic lime plaster).
- Non-hydraulic cement will not set in wet conditions or underwater, rather it sets as it dries and reacts with carbon dioxide in the air. It can be attacked by some aggressive chemicals after setting.
