In recent years, in order to reduce self-weight of structural elements, the use of SCP(Steel Concrete Plate) is getting increased. Since SCP has complicated sectional shape and includes large amount of studs, the use of shrinkage reduction concrete is required. Therefore, in this study, to prevent the restrained shrinkage behavior by stud, the effects of using expansive agent (EA) and shrinkage reducing agent (SRA) was investigated.
