The high alkaline media, such as that contained in the pores of the concrete (pH about 12-13) promotes the formation of a protective oxide layer on the surface of the steel used as reinforcement that prevents it from corrosion. However, the presence of chlorides can lead to damaging effects on passivity and the appearance of localized pitting corrosion when chloride ions reach the metal/concrete interface. In addition to this phenomenon, carbonation processes over the solution contained into the pores of the concrete causes severe corrosion problems due to a drop in pH (under the value of 9) that turns the passive state to an active corrosion process. These two factors lead to the corrosion and deterioration of the RCS with the result of a less stable and secure structure and the subsequent costs in maintenance and reparation works. Because of these circumstances, stainless steel began to be used as reinforcing material in RCS in places where carbon steel presented protection deficiencies. The interest in stainless steel reinforcements is a result of its resistance to a great variety of environments and its property of self-regeneration after partial destruction of its passive film. As a result, structural service life spans of stainless steel reinforced structures are increased with respect to traditional carbon steel ones. Stainless steel reinforced concrete was first used in the construction of a pier built in the Gulf of Mexico (Port of Progresso, Yucatán, Mexico), between 1937 and 1941. The latest inspection of the structure revealed that it is virtually free of corrosion. USA, Canada, Australia and some European countries are currently using stainless steel as reinforcements in RCS...

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Se ha analizado el comportamiento frente a la corrosión por cloruros de una nueva armadura de acero inoxidable dúplex bajo contenido en níquel, la AISI 2001, para lo cual se han tomado a efectos comparativos las armaduras de acero austénitico AISI 304 y dúplex AISI 2304 y se han embebido en probetas de mortero de cemento Portland contaminado con diferentes concentraciones de cloruro cálcico. Las probetas se han mantenido con el 95% de humedad relativa durante un período de dos años, durante el cual se han realizado mediciones electroquímicas para estudiar su evolución. Se ha monitorizado el potencial de corrosión y la resistencia de polarización mediante técnicas de corriente continua, y se ha aplicado la espectroscopía de impedancia electroquímica (EIS). Además, se ha caracterizado la composición de la capa pasiva de los aceros mediante espectroscopía fotoelectrónica de rayos X (XPS). El comportamiento de la nueva armadura AISI 2001 en el período estudiado ha sido muy similar al de la austenítica AISI 304 y la dúplex AISI 2304. Este buen comportamiento frente a la corrosión, junto con el menor coste económico de las armaduras de acero inoxidable AISI 2001, las hace muy interesante para su utilización en estructuras de hormigón armado sometidas a clases de exposición agresivas con presencia de iones cloruro.

Book Synopsis Classical Thermodynamics of Non-Electrolyte Solutions by : H. C. Van Ness
Download or read book Classical Thermodynamics of Non-Electrolyte Solutions written by H. C. Van Ness and published by Elsevier. This book was released on 2013-10-22 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical Thermodynamics of Non-Electrolyte Solutions covers the historical development of classical thermodynamics that concerns the properties of vapor and liquid solutions of non-electrolytes. Classical thermodynamics is a network of equations, developed through the formal logic of mathematics from a very few fundamental postulates and leading to a great variety of useful deductions. This book is composed of seven chapters and begins with discussions on the fundamentals of thermodynamics and the thermodynamic properties of fluids. The succeeding chapter presents the equations of state for the calculation of the thermodynamic behavior of constant-composition fluids, both liquid and gaseous. These topics are followed by surveys of the mixing of pure materials to form a solution under conditions of constant temperature and pressure. The discussion then shifts to general equations for calculation of partial molal properties of homogeneous binary systems. The last chapter considers the approach to equilibrium of systems within which composition changes are brought about either by mass transfer between phases or by chemical reaction within a phase, or by both.
Book Synopsis Soil and Sediment Remediation by : Piet Lens
Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.
