| Abstract: | This article introduces the shrinkage's types in concrete and also analysis the relationship between the shrinkage and cracks.Inferred from practical project,we employ the finite element software to improve this relationship.It explains the reason why crack appeared from the angle of concrete shrinkage.This theory is useful to prevent the cracks in the practical projects. |
