摘要: Abstract The integration and permeability of the interface between concrete layers a dam considerably affect its structural functionality safety. To understand properties, several tests were conducted to examine various characteristics specimens with different layer interfaces. mechanical property in terms bond strength was assessed using splitting tensile test, which affected by interval time. On other hand, ultrasonic pulse test used confirm influence on attenuation. chloride water also investigated means rapid permeability, alternating current resistance, tests. results these proved that longer times lead weaker higher are harmful structures. change rules properties confirmed optical micrograph hardness distribution overlay transition zone. Finally, relationships among analyzed, strong correlations demonstrated non-destructive electrical could be employed predict evaluate layered interface.
