Assessing Structural Vulnerabilities: Analyzing the Effects of Wildfires on Power Industry Steel Infrastructure

Product Number: 51324-21141-SG

Author: Mehrooz Zamanzadeh; George T. Bayer; Anil Kumar Chikkam; Edward Larkin; Clinton Char

Publication Date: 2024

$40.00

This paper focuses on the detrimental effects of wildfires on steel structures within the power industry, specifically examining the degradation of mechanical properties in structural materials and protective coatings due to high-temperature exposure. It discusses the impact on transmission and distribution structures, as well as the generation of gases and corrosive substances during wildfires. Furthermore, the paper investigates the influence of high temperatures on the mechanical properties of bare structural steel and the degradation of galvanized steel coating layers. Additionally, it explores the thermal degradation of organic coatings, changes in concrete mechanical properties, and the application of non-destructive techniques for condition assessment, including remote temperature monitoring, on structures exposed to wildfires. This research provides valuable insights into the effects of wildfires on power industry steel structures, enabling better understanding and the development of effective mitigation strategies to safeguard infrastructure and ensure its resilience in fire-prone areas.

Carbonation-Induced Corrosion Assessment for Reinforced Concrete Structures

Rebar corrosion induced by carbonation of concrete can occur in structures in both wet and dry exposures. This corrosion can become increasingly relevant in buildings as housing structures age and concrete carbonation occurs. The corrosion risk can vary depending on inter-related factors that include design, materials, and environmental exposure. The risk of corrosion furthermore can be assessed by the corrosion initiation and propagation phases. In this work two sets of testing were performed, including large scale concrete column testing to assess the corrosion behavior of steel subjected to loading and small-scale concrete testing to identify the effect of material and moisture condition environments on carbonation penetration. Concrete was cast with different water-to-cement ratio, limestone aggregate size, and conditioned in various moisture environments. The concrete specimens conditioned in wet conditions maintained in extended accelerated carbonation conditioning for up to 1 month of continuous carbonation of near 100% CO2 at 20 psi did not yield any significant carbonation penetration due to the slow rate of CO2 penetration. Concrete carbonation for the concrete specimens maintained in the dry condition fully carbonated within 67 hours and significant carbonation occurred for the concrete specimens maintained at 75%RH. In the carbonated concrete, the corrosion rate ranged from 0.2-0.8 µA/cm2. In presence of an external compressive force, the corrosion rates were similar; however, the time to corrosion initiation was delayed in time by a factor of 1.6-2. It is evident that both corrosion initiation and propagation should be considered when establishing recommendations for structural health monitoring and inspection.

CHALLENGES OF COATING A POWERHOUSE FLOOR IN A REMOTE HYDRO ELECTRIC PLANT

Product Number: 51218-137-SG

Author: Brian O'Farrell

Publication Date: 2018

$20.00

The coating of concrete floors is always challenging. Unlike walls, ceilings, tanks, bridges and other structures floors have vehicular and pedestrian traffic. This usually means that they are coated during off hours with tight schedules. Contractors need to plan the projects to meet the needs and schedules of owners. Often times this means multiple trips to the facility to review the scope of work and provide workable schedules. Required testing is generally performed prior to the scheduled start of work or after the floors are back in service.

Chloride-induced Corrosion of Reinforcing Steels Used in Concrete Structures at Various Temperatures

Product Number: 51323-18920-SG

Author: Nafiseh Ebrahimi, Jieying Zhang, and Amin Ghaziaskar

Publication Date: 2023

$20.00

Steel rebar in concrete is in a passive state due to the high pH of concrete. The hydroxyl (OH-) ions in highly alkaline concrete pore solution act as inhibitors and promote passive film stability, while chloride ions lead to passive film breakdown. Leckie and Uhlig1 first explained the counter effect of inhibitor action with chloride concentration. They proposed a competition between the inhibitor and chloride anions for adsorption on the passive surface.

COATING CONCRETE AFTER 28 DAYS . . Why There Is No Magic In This Number

Product Number: 51218-134-SG

Author: Randy A. Nixon

Publication Date: 2018

$20.00

This paper will discuss the many factors affecting the timing for concrete shrinkage (and related cracking) as well as the rate of loss of excess moisture which are not reliant on 28 days of concrete cure time. In addition, case histories will be presented evidencing successful coating applications on concrete well before 28 days of cure time versus coating problems experienced well beyond 28 days of concrete cure.

Coatings and Concrete: Understanding the Substrate

Product Number: 41215-919-SG

Author: Brian O’Farrell

Publication Date: 2015

$20.00

Before coating concrete, you must first know what the substrate is that you are working on. Since all concrete floors are not the same there is no one, size fits all system. In fact, many buildings will have several different types of concrete floors. Add to that the different mix designs, placement techniques and environmental conditions and you end up with a menagerie of concrete floors exhibiting a wide variety of properties.
