Book excerpt: This study evaluated various techniques that use mechanical waves for the evaluation of critical concrete properties, such as proper consolidation of the concrete during placement and strength development; changes in modulus; and the detection of cracks, voids, and delaminated regions. The methods evaluated were ultrasonic shear-wave tomography, ultrasonic pulse velocity, crosshole sonic logging, sonic echo-impulse response, spectral analysis of surface waves, and the use of an impact echo scanner on pavements and bridge structures. Ultrasonic shear-wave tomography can be successfully used to determine the major distressed areas in pavements. Crosshole sonic logging can detect voids in drilled shafts and can indicate concrete performance and quality. Sonic echo-impulse response can reliably detect voids but is not always able to establish a precise location because of the potential variability in wave velocity. However, it can still provide useful thickness or depth information. In addition, detection of distress is limited by the embedded length-to-diameter ratios of the foundation element being examined. The use of ultrasonic pulse velocity can improve the accuracy of sonic echo-impulse response measurements by providing the actual velocity of the concrete being evaluated. Use of the impact echo scanner can provide delamination data for structures with smooth surfaces. In addition to detecting the condition of the concrete elements, these methods can be used to help determine compliance with end-result specifications. Quality control and acceptance using end-result specifications requires at least three test results to determine variability, which can be easily obtained using nondestructive test methods. The results regarding spectral analysis of surface waves were promising, but additional validation work is required to determine the abilities of this technique to assess asphalt-overlaid concrete decks. This study showed that nondestructive mechanical wave methods can be successfully used in determining concrete quality and the extent of distress in concrete structures. The study recommended that these methods be used by the Virginia Department of Transportation for condition assessment. The next step is to continue collecting data on pavements and bridge structures using these techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The Concrete Solutions series of International Conferences on Concrete Repair began in 2003, with a conference held in St. Malo, France in association with INSA Rennes, followed by the second conference in 2006 ( with INSA again, at St. Malo, France), and the third conference in 2009 (in Padova and Venice, in association with the University of Padova). Now in 2011, the event is being held in Dresden in Germany and has brought together some 112 papers from 33 countries. Whereas electrochemical repair tended to dominate the papers in earlier years, new developments in structural strengthening with composites have been an increasingly important topic, with a quarter of the papers now focusing on this area. New techniques involving Near Surface Mounted (NSM) carbon fibre rods, strain hardening composites, and new techniques involving the well established carbon fibre and polyimide wrapping and strengthening systems are presented. Seventeen papers concentrate on case studies which are all-important in such conferences, to learn about what works (and what doesn’t work) on real structures. Thirteen papers are devoted to new developments in Non-Destructive Testing (NDT). Other topics include service life modelling, fire damage, surface protection methods and coatings, patch repair, general repair techniques and whole life costing. This book is essential reading for anyone engaged in the concrete repair field, from engineers, to academics and students and also to clients, who, as the end user, are ultimately responsible for funding these projects and making those difficult decisions about which system or method to use.

Available in PDF, EPUB and Kindle. Book excerpt: The mechanisms by which buildings and infrastructures degrade are complex, as are the procedures and methods for inspection and for rehabilitation. This book examines the various problems caused by non-uniform deformation changes, poor durability, and natural and human disasters such as earthquakes and fire. Attention is given to the causes and mechanisms of the deterioration. General procedures and commonly used techniques for inspection and evaluation of existing infrastructures are introduced. The desk study, destructive test, and non-destructive test are discussed – in particular the newly developed non-destructive methods for deterioration monitoring. The book then moves on to conventional renovation techniques such as patch and steel plate strengthening, which meet the requirements of normal practice. Special attention is paid to compatibility between repair materials and degraded materials. Fibrous composite materials are then introduced as a basis for innovative repair techniques, and different fibre and matrix properties are outlined, as are newly developed inorganic binders as a matrix for fibrous composites. Finally, advanced rehabilitation techniques using fibrous composite are described. Fundamental issues such as bonding and failure mechanisms are then discussed in detail. Fibrous composite strengthening techniques for beam, wall, column and slabs are covered, including shear strengthening, flexural strengthening, and fillet winding, as are codes of practice for retrofitting with fibrous composites. This caters to students and academics world-wide and serves as a "tool book" for concrete and structural engineering professionals.
