: Journal of Materials in Civil Engineering Volume 38, Issue 5 Practical Applications Concrete is a complex composite material, which leads to a certain discreteness in the measured values of concrete even under uniform test conditions. To overcome the difficulty of concrete discreteness, the probability statistics method is usually used. For example, the compressive strength with a 95% reliable probability is generally used as the standard value of concrete compressive strength.

Practical Applications Creep is one of the important properties of concrete. It is a phenomenon wherein the deformation of concrete structure increases over time when it is under a sustained load. Creep is important because it can reduce the temperature stress and shrinkage cracks of concrete structures. To determine how concrete behaves under different types of load, engineers conduct concrete creep tests.
