Available in PDF, EPUB and Kindle. Book excerpt: A study on the effects of rigid overlays on corrosion rate of steel in reinforced concrete bridge decks was carried out using three-electrode linear polarization (3LP) instrumentation. Corrosion currents were measured immediately prior to placement of overlays, and one and two years after placement. Four latex modified concrete (LMC), three superplasticized dense concrete (SDC), and three condensed silica fume concrete (CFSC) overlays were included in the study. Results of the study indicate that for LMC and CSFC overlays there is a decrease of from 1 to 2 mA/sq ft in corrosion current after 2 years of service. The most consistent decreases were observed for the CSFC overlays. Results for the SDC overlays were less consistent.

Download or read book Corrosion of Steel in Concrete written by John P. Broomfield and published by CRC Press. This book was released on 2023-01-31 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of Steel in Concrete: Understanding, Investigation and Repair is a guide for designing, constructing and maintaining reinforced concrete structures, such as buildings and bridges which are subject to reinforcement corrosion. It presents the basics of theory and practice in steel corrosion in concrete and reviews the latest research and developments, such as progress on measuring the corrosion threshold for chloride-induced corrosion. This third edition compares the currently proliferating major national and international standards and guidance documents. New developments are considered, such as hybrid anodes for electrochemical treatment and the latest research and developments in assessment, such as the use of ground penetrating radar to measure the chloride content of the concrete cover. It overhauls coverage of electrochemical repair and rehabilitation techniques and outlines recent innovations in structural repair and construction and investigates their implications for durability. The book is ideal for practitioners and graduate students in structural engineering and concrete technology.

This book was released on 2009-01-01 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognised that corrosion of steel is extremely costly and affects many industry sectors, including concrete construction. The cost of corrosion of steel reinforcement within concrete is estimated at many billions of dollars worldwide. The corrosion of steel reinforcement represents a deterioration of the steel which in turn detrimentally affects its performance and therefore that of the concrete element within which it has been cast. A great amount of work has been undertaken over the years concerning the prevention of corrosion of steel, including the application of coatings, which has included the study of the process of corrosion itself, the properties of reinforcing steels and their resistance to corrosion as well as the design of structures and the construction process. The objective of fib Bulletin 49 is to provide readers with an appreciation of the principles of corrosion of reinforcing steel embedded in concrete and to describe the behaviour of particular steels and their coatings as used to combat the effects of such corrosion. These include galvanised reinforcement, epoxy coated reinforcement, and stainless reinforcing steel. It also provides information on the relative costs of the materials and products which it covers. It does not deal with structure design or the process of construction or with the post-construction phase of structure management including repair. It is hoped that it will nevertheless increase the understanding of readers in the process of corrosion of reinforcing steels and the ability of key materials and processes to reduce its harmful effects.
Book Synopsis Blacktop Resurfacing of Bridge Decks by : Dunja Mikulic
Download or read book Blacktop Resurfacing of Bridge Decks written by Dunja Mikulic and published by . This book was released on 2001 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Durability of concrete bridge decks to mechanical and environmental effects is examined for the purpose of evaluation of effects of blacktop resurfacing of bridge decks. Aggressive environmental actions on reinforced concrete are described, classified and equivalent environmental loads presented. To explain effects of aggressive environmental loads, concrete transport properties dependent on concrete structure, external effects, mechanisms in concrete, and chemical reactions of aggregates are discussed in detail. Mathematical formulation (model) for durability design of reinforced concrete structures is presented. The model allows estimation of various stages in corrosion progression in reinforced concrete structures: from initiation to propagation of reinforcement corrosion. The process can be effectively described using fuzzy sets. To enable evaluation of susceptibility of reinforced concrete to corrosion attacks, various electrochemical and nonelectrochemical methods are presented and discussed. Various types of overlays, that can be employed for bridge deck protection and/or repair, are discussed with respect to required properties. Special attention is given to application of corrosion inhibitors in both concrete and asphalt concrete, if used as a bridge deck overlay.
Book Synopsis Nondestructive Corrosion Evaluation of Reinforced Concrete Bridge Decks with Overlays by : Dewei Meng
Download or read book Nondestructive Corrosion Evaluation of Reinforced Concrete Bridge Decks with Overlays written by Dewei Meng and published by . This book was released on 2020 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete corrosion induced by deicing agents can decrease the durability of concrete bridge decks by causing cross-sectional loss of reinforcement, concrete delamination, and spalling owing to the expansion of corroded reinforcement. The installation of overlays can extend the service life of the deteriorated decks. However, overlays present challenges in the evaluation of the corrosion condition of the underlying decks. This laboratory study employed three nondestructive testing (NDT) methods to assess the effects of seven types of overlays on corrosion evaluation for concrete bridge decks. The NDT methods were electrical resistivity (ER), ground-penetrating radar (GPR), and half-cell potential (HCP). The ER method could not evaluate the corrosive environment in the concrete decks through the overlays. The GPR method could detect the corrosive environment through four of the seven overlays. The HCP method could detect the decrease of electrical potential over the actively corroded reinforcement for all seven specimens; however, only two of the seven specimens could be identified as having active corrosion per ASTM C876-15, Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete . Overlay debonding did not affect GPR and HCP testing results in this study.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of construction practices and material properties on the performance of concrete bridge decks are evaluated. Emphasis is placed on comparing bridge decks with silica fume and conventional concrete overlays and determining if the silica fume overlays commonly used on bridges in Kansas are performing at a level that justifies the extra cost and construction precautions. Forty continuous steel girder bridges, 20 with silica fume overlays, 16 with conventional overlays and four with monolithic bridge decks are included in the study.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents a study on estimating the service life cycle of reinforced concrete bridge components exposed to chloride-laden environments. Current treatment options are identified and an opinion survey was used to obtain first estimates of service life. To estimate the service life of untreated and rehabilitated bridge decks, data from 52 bridge decks distributed in different environmental conditions were collected. Models estimating the service life of untreated and rehabilitated bridge decks were developed and compared with models developed based on historical data and the time-to-rehabilitate model.
