Creep of the concrete is influenced by

Creep Of Concrete:

• Creep in concrete is a time-dependent phenomenon. It is the “inelastic deformation” of concrete under “sustained stress”.
• Creep can be defined as the elastic and long-term deformation of concrete under a continuous load.
• Generally, a long-term pressure changes the shape of the concrete structure and the deformation occurs along the direction of the applied load.
• When the continuous load is removed, the strain is decreased immediately.
• The amount of the decreased strain is equal to the elastic strain at the given age.
• This quick recovery is then followed by a continuous decrease in strain, known as creep recovery which is a part of the total creep strain suffered by the concrete. Creep Coefficient. The ratio of the ultimate creep strain to the elastic strain at the age of loading is termed as creep coefficient.

​​Factors Affecting Creep Of Concrete:
1. Water-cement Ratio:

• The rate of creep is increased with an increasing water-cement ratio.

2. Humidity:

• It is influenced by the humidity and drying conditions of the atmosphere.

3. Age Of Concrete:

• The rate of creep rapidly decreases with time. The time taken by a concrete structure to attain creep is 5 years.

4. Aggregate:

Aggregates with moisture movement and low elastic modulus cause a large amount of creep. The rate of creep generally decreases with the increase of the size of aggregates.
5. Admixtures:

• Some admixtures (mainly accelerators) are also responsible for causing creep in concrete.

Other Factors:
Types of cement.
Entrained air.
Concrete strength.
Improper curing etc.​
