摘要：

In this paper, an extensive review for concrete-to-concrete bond strength was conducted. Several major factors that affect the bond strength between concrete layers such as differential stiffness, shrinkage and age, concrete type, surface preparation, and variation of compressive strength between layers were considered in the discussion. In addition, the paper presents some of the most common tests performed to measure the bond strength of a sample, such as slant shear test, direct shear test, split tension test, and pull off test. Additionally, several codes recommendations for concrete-to-concrete bond in structural applications were presented and discussed.
