But the drying shrinkage of the practical concrete structure due to the change of environmental factors such as humidity and wind speed would happen, therefore, the drying shrinkage of concrete in practical engineering can be considered synonymous as with constraint conditions in this test, so the test under high degree of constraint are more reasonable.
