Permanent loads
What is the main factor influencing the creep of concrete?
Permanent loads
How would you describe the deformations in concrete under creep?
Time-dependent and permanent
Which factor does NOT play a significant role in influencing the creep of concrete?
Cyclic loads
How does creep behave as the relative humidity decreases?
Creep increases
What is the relationship between ambient relative humidity and creep?
Creep increases as humidity decreases
In what way does creep respond to changes in relative humidity?
Creep increases
What happens to creep when relative humidity rises?
Creep remains constant
How is creep affected by higher levels of relative humidity?
Creep increases
What happens to creep as the water-cement ratio increases?
Creep increases
What happens to concrete if the load is maintained for a considerable period of time?
It undergoes additional deformations.
How does the age of concrete affect the rate of creep?
The rate of creep rapidly decreases with time
How does concrete behave when subjected to a constant load over time?
It experiences additional deformations.
What effect does a high water-cement ratio have on the strength of concrete?
Decreases strength
What change occurs in concrete if the load is kept constant for an extended period?
It undergoes creep deformation.
How does the rate of creep change with low w/c ratio?
Decreases
If a load is applied to concrete for a long time, what deformation can be expected?
Creep deformation

Improves durability
What is the result of maintaining a load on concrete without any change for an extended period of time?
Additional deformations
How does creep affect internal stresses in concrete structures?
Reduces them
