Incorporating Corrosion in Reliability-Based Design of Anchored Bulkheads
Corrosion of steel is an important factor in the design of marine structures. A reliability analysis of anchored bulkheads showed that corrosion changes the critical failure mode from...
Advancing Anchorage Technology
An overview of earth anchorage technology, with emphasis on current U.S. corrosion protection practice as compared to that used in Europe. Comments from U.S. practitioners involved in...
Investigation of Concrete at a Middle East Plant
In recent years, reinforced concrete construction in the Middle East has been beset by durability problems. The causes include availability of a limited number of skilled workers, marginal...
Corrosion Fatigue of Deepwater Offshore Materials
Evaluation of the fatigue life of offshore structures operating in depths of up to 10,000 feet (3,048 m) requires knowledge of the combined effect of axial and hydrostatic loading on the...
Tunnel Takes Cathodic Protection
Cathodic protection is nothing new for bridges and parking garages, but it has never been installed in a tunnel�until now. As part of a $15 million rehabilitation project, the method is...
Put to the Test
In the construction industry, the concept of life-cycle cost applies not only to the infrastructure itself, but to the materials that go in to building that infrastructure. To improve...
High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...
Condition Assessment Experience with Silos and Bunkers
This paper presents a methodology for condition assessment of coal silos and bunkers for retrofitting projects. Some typical problems such as corrosion, erosion, vibrations and buckling...
Improved Corrosion Protection for Flue Gas Systems Utilizing a Dual Liner Concept
A unique system of corrosion resistant materials has shown excellent performance and durability in flue gas systems for fossil plants, cogeneration plants, waste incinerators and waste-to-energy...
Designing for Corrosion Control
This presentation will discuss designing from several aspects: a. Designing of the item to lessen the affects of corrosion. b. Selection of non-corrosive materials in the designing process...
Degradation Mode Surveys of High Performance Candidate Container Materials
Corrosion resistant materials are being considered for the metallic barrier of the Yucca Mountain Project's high-level radioactive waste disposal containers. Nickel-chromium-molybdenum...
An Electrochemical Approach to Predicting Corrosion Performance of Container Materials
The pitting potentials of nickel-rich Alloy 825 are measured in chloride-containing solutions at different temperatures and adjusted to different pH values. The pitting potentials were...
Potential Uses of Lead in Nuclear Waste Disposal
In order for lead to be considered as a nuclear waste packaging material, it must be shown that it has adequate corrosion resistance, and that it does not degrade the properties of other...
Modelling Studies for the Assessment of the Advanced Cold Process Canister
The Advanced Cold Process Canister (ACPC) is a new concept for the encapsulation of spent nuclear fuel for geological disposal. It consists of steel canister encased in a copper overpack....
Effect of Ionizing Radiation on the Waste Package Environment
The radiolytic production of nitrogen oxides, nitrogen acids and ammonia are discussed in relation to the expected environment in a high-level waste repository that may be constructed...
Interruption of Sewer Crown Corrosion?Ecological Solutions
Competitive inhibition of acid production by thiobacilli was investigated by encouraging the growth of potential competitors. Two-organism competition experiments (Thiobacillus sp. vs....
Hydrogen Sulfide in Hydropower Reservoirs
Hydrogen sulfide is toxic to aquatic life and corrosive to construction materials at concentrations that are considerably lower than detection limits of analytical procedures commonly...
Corrosion Below: Sewer Structures
When a sewer system fails, the cause is often not the pipe but a manhole, junction or other special-purpose structure. Most of these structures are concrete, either cast in place or precast....
Structural Investigation of Marina Del Rey Seawall
The Marina del Rey Seawall was constructed by various contractors between 1959 and 1961. It is composed of 660 panels totaling 39,600 linear feet. The seawall configuration is a type normally...
Time Variant Reliability Analysis Considering Corrosive Effects
In this study the influence of corrosion is determined as a function of the stress intensity factor, the frequency and the stress ratio of the loading process. The present study investigates...
