Review on Behavior of Concrete-concrete Interface and Its Application in Composite Concrete Structures

Abstract:

Concrete-concrete interface is commonly found in concrete structures. The shear resistance of the concrete-concrete interface is the basis for ensuring the integrity of different concrete parts in the structure. In this paper， we introduce the shear transfer mechanism， the design expression of shear stress， the bond behavior of the concrete-concrete interface and the factors affecting the behavior of the concrete-concrete interface. Then， we discuss the durability of the concrete-concrete interface. Finally， the conceptual design frame of the concrete-concrete interface is built.
