Relationships between measurements of nondestructive testing and quality characteristics of concrete relative to durability were investigated in order to establish direct quality inspection methods of concrete in structures. The ultrasonic, rebound and combined methods were used for the nondestructive testing. Correlation between the pulse velocity and the tensile strength, dynamic modulus of elasticity, bulk density and water absorptivity were stronger than the one with compressive strength. The combined method was effective to increase the reliability of testing to predict quality of concrete in structures.
