Using reference electrodes to monitor the electrochemical potential of steel reinforcement in concrete is a well established technique for assessing the severity of corrosion and for controlling cathodic protection systems. This report gives a state-of-the-art overview of the electrochemical and physical characteristics and performance of embeddable reference electrodes for concrete, and the method used for installing them. The report first reviews electrochemical potential and reference electrodes in general. It then assesses the different types of reference electrodes for concrete. Finally, it considers key issues such as location and quality control which need to be considered when installing reference electrodes in steel-reinforced concrete structures. Provides a state-of-the-art overview of the electrochemical and physical characteristics and performance of embeddable reference electrodes for concrete Considers key issues such as location and quality control

There is a concern that none of the existing concrete-embeddable reference electrodes that are being used as a convenient means for monitoring the condition of the reinforcing steel in concrete bridges or the operation of cathodic protection systems for permanently halting steel corrosion in these structures may have sufficient stability of at least 25 years. This study examines the possibility of using stable-potential galvanic couples (SPGC), which rely on different rate constants between the component metals of each couple to maintain stable potentials, as a new concept for developing better concrete-embeddable reference electrodes. Each SPGC relies on the different rate constants between the component metals to maintain a characteristic stable potential and can be classified as either noble-noble, noble/active-passive, noble-active or active-active. The long-term and the short-term stability of the potentials of different galvanic couples (in saturated calcium hydroxide), relative to both a saturated calomel electrode and a commercial manganese dioxide electrode, were assessed. The cathode-to-anode area ratio aspects of some couples were also investigated and it was determined that the area ratio could be used to optimize couple stability. Mixed potential theory was used to characterize these electrodes and explain the stability behavior. Several potentially successful couples, that exhibited potential shifts of less than 10mV, were identified and embedded in concrete (both with and without added chloride) for further investigation. This resulted in the identification of three promising candidate couples (Cu-W, Ni-W, and Cu-Ni) that can be developed into very stable concrete-embeddable reference electrodes by optimizing the electrode design parameters such as anode-to-cathode area ratio and geometry.

The failure of the UN climate change summit in Copenhagen in December 2009 to effectively reach a global agreement on emission reduction targets, led many within the developing world to view this as a reversal of the Kyoto Protocol and an attempt by the developed nations to shirk out of their responsibility for climate change. The issue of global warming has been at the top of the political agenda for a number of years and has become even more pressing with the rapid industrialization taking place in China and India. This book looks at the effects of climate change throughout different regions of the world and discusses to what extent cleantech and environmental initiatives such as the destruction of fluorinated greenhouse gases, biofuels, and the role of plant breeding and biotechnology. The book concludes with an insight into the socio-religious impact that global warming has, citing Christianity and Islam.

Whilst most structures made using concrete and cement-based composites have not shown signs of premature degradation, there have been notable exceptions. In addition, there is increasing pressure for new structures to remain in serviceable condition for long periods with only minimal maintenance before being recycled. All these factors have highlighted the issues of what affects the durability of these materials in different circumstances and how material properties can be measured and improved. Durability of concrete and cement composites summarises key research on these important topics. After an introductory chapter, the book reviews the pore structure and chemistry of cement-based materials, providing the foundation for understanding the particular aspects of degradation which are discussed in the following chapters. These include dimensional stability and cracking processes, chemical and microbiological degradation of concrete, corrosion of reinforcing and prestressing steels, deterioration associated with certain aggregates, effects of frost and problems involving fibre-reinforced and polymer-cement composites. With its distinguished international team of contributors, Durability of concrete and cement composites is a standard reference for all those concerned with improving the service life of structures using these materials. Analyses a range of materials such as reinforced steel in concrete, pre-stressed concrete and cement composites Discusses key degradation phenomena such as cracking processes and the impact of cold weather conditions A standard reference for those concerned with improving the service life of structures using concrete and cement based composites

Corrosion of Steel in Concrete provides information on corrosion of steel in atmospherically exposed concrete structures and serves as a guide for those designing, constructing and maintaining buildings, bridges and all reinforced concrete structures. This new edition incorporates the new European standards as well as USA and other international standards. It also covers developments in galvanic and impressed current cathodic protection, new electrochemical techniques such as electro-osmosis, and stainless steel clad reinforcing bars. The corrosion of reinforcing steel in concrete is a major problem facing civil engineers and surveyors throughout the world today. There will always be a need to build structures in corrosive environments and it is therefore essential to address the problems that result. This is a book to educates about and forms a guide to the problems of corrosion, its causes and how to find solutions.

The condition assessment of aged structures is becoming a more and more important issue for civil infrastructure management systems. The continued use of existing systems is, due to environmental, economical and socio-political assets, of great significance and is growing larger every year. Thus the extent of necessary repair of damaged reinforced concrete structures is of major concern in most countries today. Monitoring techniques may have a decisive input to limit expenditures for maintenance and repair of existing structures. Modern test and measurement methods as well as computational mechanics open the door for a wide variety of monitoring applications. The need for quantitative and qualitative knowledge has led to the development and improvement of surveillance techniques, which have already found successful application in other disciplines such as medicine, physics and chemistry. The design of experimental test and measurement systems is inherently an interdisciplinary activity. The specification of the instrumentation to measure the structural response will involve the skills of civil, electrical and computer engineers. The main aim of fib Commission 5, Structural servicer life aspects, is to provide a rational procedure to obtain an optimal technical-economic performance of concrete structures in service and to ensure a feedback of experience gained to design, execution, maintenance and rehabilitation. Against this background fib Task Group 5.1 Monitoring and Safety Evaluation of Existing Concrete Structures had been established to evaluate the existing practice worldwide. The objective of this state-of-art report is to summarize the most important inspection and measuring methods, to describe the working process and to evaluate the applicability to structural monitoring. Particular emphasis is placed upon non-destructive systems, lifetime monitoring, data evaluation and safety aspects.
