Creep: Creep is the property by virtue of which a material undergoes additional deformation over and above that due to applied load with passage of time under sustained loading. IS 456:2000 Clause 6.2.5 Creep of concrete: Creep of concrete depends, on the stress in the concrete, age at loading and duration of loading. As long as the stress in the concrete does not exceed

of its characteristic compressive strength.

According to table, if age of loading increases than creep coefficient of concrete will decreases.
