... in terms of electrical resistivity, concrete shrinkage, and the effect of fiber clumping. Electrical resistivity testing conformed to ASTM C1760-126 to identify resistance to penetration of chloride ions. Testing included both 4-point surface resistivity and 2-point bulk resistivity testing. Shrinkage...

... ABSTRACT For natural gas pipelines, it is important to monitor and locate corrosion incidents along the long-distance pipelines. This is especially true for internal corrosion, as it is more challenging to access the inside of the pipes. Distributed optical fiber-based sensors (DOFS) provide...

... Abstract This study aims to monitor the spatial distribution of pitting corrosion occurring in steel rebars in concrete structures using an optical frequency domain reflectometry (OFDR) distributed optical fiber sensor. A concrete slab was fabricated containing eight steel rebars. After curing...

... optical fiber-based corrosion and humidity sensors at ambient pressure. In this work, optical fiber sensors were interrogated using an optical backscatter reflectometer and tested under high pressures to simulate pressurized pipeline conditions. When pressurized to 900 psi with dry N 2 , strains of single...
