Concrete remains in its fresh state from the time it is mixed until it sets. During this time the concrete is handled. Properties of fresh concrete include workability, air content, temperature and setting time. It is important to perform some tests on fresh concrete.

Concrete is referred to as fresh when the setting and hardening process has not yet started. Fresh concrete can be deformed and poured which. The knowledge about the property of fresh concrete enables us to study the behavior of concrete in its hardened state and adjust them. All the characteristics above describe many different aspects of concrete behavior. The term workability is used to represent all the qualities mentioned.
