Weathering steel (ASTM A588, Grade B) and steels with 0.021 and 0.21 percent copper were tested for corrosion resistance in marine, rural, and two industrial environments. The results of these tests are represented well by kinetic equations of the form C = AtB, where C is the corrosion loss, t is time, and A and B are constants. On the basis of the time required to achieve a 250-?m (0.01 in.) thick ness loss that is calculated using these equations, the weathering steel is 6 to 19 times more durable than the 0.021 percent copper steel and 2 to 10 times more durable than the 0.21 percent copper steel.

Weathering steels ASTM A 242-Type 1 and ASTM A 588-Grade B and steels with 0.21 and 0.021% copper are tested for atmospheric corrosion resistance in marine, rural, and industrial environments. The 16-year atmospheric exposure test results obey well the kinetic equations of the form C = AtB, where C is the corrosion loss, t is time, and A and B are constants. The corrosion resistance of steels is compared on the basis of times required to achieve a 250 ?m thickness loss calculated using the rate equations. In these environments, weathering steel ASTM A 242 is at least 16 times more corrosion resistant than the 0.021% copper steel and at least four times more corrosion resistant than the 0.21% copper steel. Similarly, weathering steel ASTM A 588 is about eight times more durable than the 0.021% copper steel and at least two times more durable than the 0.21% copper steel.

Eight-year atmospheric corrosion tests of A 588B weathering steel were conducted in industrial, marine, and rural environments. The material was tested following two types of heat treatment: (1) quenched-and-tempered to produce a tempered martensite microstructure, and (2) normalized to produce a microstructure comprised of ferrite and pearlite. The results of these tests indicate that these heat treatments have no effect on the corrosion resistance, and that the performance of weathering steels can be estimated solely on the basis of composition.

ATMOSPHERIC CORROSION Presents a comprehensive look at atmospheric corrosion, combining expertise in corrosion science and atmospheric chemistry Atmospheric corrosion has been a subject of engineering study, largely empirical, for nearly a century. Scientists came to the field rather later on and had considerable difficulty bringing their arsenal of tools to bear on the problem. Atmospheric corrosion was traditionally studied by specialists in corrosion having little knowledge of atmospheric chemistry, history, or prospects. Atmospheric Corrosion provides a combined approach bringing together experimental corrosion and atmospheric chemistry. The second edition expands on this approach by including environmental aspects of corrosion, atmospheric corrosion modeling, and international corrosion exposure programs. The combination of specialties provides a more comprehensive coverage of the topic. These scientific insights into the corrosion process and its amelioration are the focus of this book. Key topics include the following: Basic principles of atmospheric corrosion chemistry Corrosion mechanisms in controlled and uncontrolled environments Degradation of materials in architectural, transport, and structural applications; electronic devices; and cultural artifacts Protection of existing materials and choosing new ones that resist corrosion Prediction of how and where atmospheric corrosion may evolve in the future Complete with appendices discussing experimental techniques, computer models, and the degradation of specific metals, Atmospheric Corrosion, Second Edition continues to be an invaluable resource for corrosion scientists, corrosion engineers, conservators, environmental scientists, and anyone interested in the theory and application of this evolving field. The book concerns primarily the atmospheric corrosion of metals and is written at a level suitable for advanced undergraduates or beginning graduate students in any of the physical or engineering sciences.

The book entails investigative methods for better understanding of the degradation process and uses of high performance paints formulation and also compares them on mild steel (MS) and weathering steel (WS) through various AC/DC electrochemical test methods and surface characterization through electron microscopy, XRD and Raman spectroscopy. This book also deals with the corrosion studies undertaken considering three phases (solid, liquid and gas) with latest techniques and the emphasis has also been given on degradation of materials due to atmospheric corrosion as this is of immense interest to present engineers and researchers. MS has got versatile application as structural steel for construction of buildings, bridges, flyovers, pipelines etc. But this is very much prone to corrosion in industrial and marine environments in presence of harmful pollutants and other industrial effluents in addition to normal humid atmosphere. These corrosion problems are much severe in a tropical country like India with vast coastline. MS corrodes relatively faster and thus leads to colossal loss in every year and to reduce this loss some kind of protection in the form of paints and coatings is always used. Painting is an effective means but quite costly amounting 10-15% of the initial construction cost of superstructures besides cost of repainting at regular interval.

This report contains 27 papers that serve as a testament to the state-of-the-art of civil engineering at the outset of the 21st century, as well as to commemorate the ASCE's Sesquicentennial. Written by the leading practitioners, educators, and researchers of civil engineering, each of these peer-reviewed papers explores a particular aspect of civil engineering knowledge and practice. Each paper explores the development of a particular civil engineering specialty, including milestones and future barriers, constraints, and opportunities. The papers celebrate the history, heritage, and accomplishments of the profession in all facets of practice, including construction facilities, special structures, engineering mechanics, surveying and mapping, irrigation and water quality, forensics, computing, materials, geotechnical engineering, hydraulic engineering, and transportation engineering. While each paper is unique, collectively they provide a snapshot of the profession while offering thoughtful predictions of likely developments in the years to come. Together the papers illuminate the mounting complexity facing civil engineering stemming from rapid growth in scientific knowledge, technological development, and human populations, especially in the last 50 years. An overarching theme is the need for systems-level approaches and consideration from undergraduate education through advanced engineering materials, processes, technologies, and design methods and tools. These papers speak to the need for civil engineers of all specialties to recognize and embrace the growing interconnectedness of the global infrastructure, economy, society, and the need to work for more sustainable, life-cycle-oriented solutions. While embracing the past and the present, the papers collected here clearly have an eye on the future needs of ASCE and the civil engineering profession.
