U.S. House Panel Concludes State, Federal Failures behind Flint

The U.S. congressional committee investigating the water crisis in Flint, Michigan issued final letters citing failures at all levels of government, including problems at both the Michigan Department of Environmental Quality and the U.S. Environmental Protection Agency.

New U.K. Collaborative Research Project Targets Oil, Gas Corrosion

Researchers from BP and several prominent European universities were awarded a contract to investigate the processes that cause surface degradation and develop new mitigation strategies.

Researchers Eye Advanced Sensors to Monitor Buried Infrastructure

Novel advanced sensors were attached to a hazard-resilient plastic pipeline installed underground and tested through a simulated fault rupture.

New Tantalum Alloy Resists Highly Corrosive Environments

The results of recently completed trials show that adding low levels of ruthenium improve the corrosion and hydrogen enrichment resistance of a tantalum alloy in both hydrochloric and sulfuric acids at high temperatures.

Self-Consolidating Concrete Shows Promise in Bridge Repairs

A Virginia Department of Transportation investigation studied the use of self-consolidating concrete with and without galvanic anodes to repair substructure elements with vertical and overhead sections.

Study: Lack of Corrosion Controls Caused Flint Water Crisis

Led by university researchers, the findings of this new study support the understanding that lead leached into the pipes system in Flint, Michigan, because the water wasn’t treated to prevent corrosion.

Study Evaluates Chloride Limits for Structural Reinforced Concrete

Research on chloride limits for reinforced concrete found a relationship between the initial calculated total chloride content and the measured water-soluble chloride content in hardened concrete.

Device Measures Nanoscale Crevice, Pitting Corrosion in Real Time

University researchers developed a device called a surface forces apparatus (SFA) to get a real-time look at the process of crevice and pitting corrosion on confined metallic surfaces.

Battling Building Envelope Corrosion

Efficiently managing the effects of concrete corrosion can extend the life of a building; however, concrete is not the only component threatened by corrosion. On any building, both the cladding and fasteners holding it in place are exposed to varying degrees of corrosion.

New Technique Tracks Water in Concrete via Electrical Imaging

Researchers at North Carolina State University and the University of Eastern Finland are working on a novel technique for tracking water in concrete through the use of electricity.

X-Ray Analysis Used to Predict Sulfur Corrosion Rates in Crude Oil

Industry and university researchers are using x-ray techniques to develop an analysis tool to more accurately predict how sulfur compounds in crude oil could corrode processing plant equipment.

Fungi Species Could Limit Concrete Corrosion by Healing Cracks

Researchers say the application of a specific species of fungi into the concrete matrix during the mixing process could serve as an unusual candidate to help concrete heal itself.

Study: North American Waterways Becoming Saltier, More Alkaline

University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.

Investigators Find Severe Corrosion in 2015 California Gas Leak

Independent investigators found extensive corrosion on the well casing that broke open at Southern California Gas Co.'s Aliso Canyon gas storage facility in October 2015. In the aftermath, engineering consultancy Blade Energy Partners was granted authority by the California Public Utilities Commission (CPUC) to conduct a root cause analysis of the metallurgical and fractographic aspects of the gas leak.

Thermal Imaging Used for Nondestructive Testing of Concrete Pillars

Russian scientists recently used a thermal imaging technique to study the corrosion of steel reinforcement within 14 reinforced concrete pillars.
