This book was released on 1977 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Concrete Laboratory (CL) has used nondestructive testing (NDT) in the evaluation of concrete and concreting materials. In recent years, more emphasis has been placed on the inspection and structural evaluation of completed Corps of Engineers structures. The need for a capability to predict, prior to placement, certain properties of concrete mixtures after hardening has been realized. This report discusses the history, progress to date, and needs for future research and development in the field of NDT.

Book excerpt: Development of the resonant frequency technique as a method for evaluation of concrete structures is in progress. It is desirable that structures be evaluated in place, nondestructively, and in real time. The availability of digital Fourier analyzers and mathematical functions such as spectra, coherence, and transfer relationships permits the analysis of the behavior of large structures under dynamic conditions in place and in real time. An impact system has been tested which was proven more economical and versatile than the sinusoidal system currently in use. With transient loading, all frequencies are applied to the structure simultaneously rather than being swept through one at a time. Because the resonant frequency of a structure is directly related to its dynamic Young's modulus and hence its mechanical integrity, the resonant frequency technique is useful in the field as well as in the laboratory. Factors that influence the soundness and safety of a structure, such as modulus, continuity, and boundary conditions (i.e. foundation and other restraints) also directly affect the resonant frequency. Some limited work has been done with both mathematical and physical modeling to develop measurement criteria that will improve prediction of the expected resonant frequency for structures with varying geometries and varying degrees of foundation restraint. The characteristic vibrational signature of a structure may be evaluated at selected time intervals in an effort to predict service life. Improvement in modal analysis and prediction of frequencies by mathematical modeling is needed. Field work has demonstrated the feasibility of the technique. (Author).

This book was released on 2010-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative book provides a comprehensive review of the highly important subject of non-destructive evaluation of reinforced concrete structures. Engineers have a range of sophisticated techniques at their disposal to assess the condition of reinforced concrete structures that do not cause material damage and which usually enable the structure to be used while the surveys are carried out. Non-destructive evaluation of the infrastructure also plays a key role in calculating and prioritising where money should be spent on repair or replacement. Providing details of related techniques and case studies, this book offers an overview of how to plan and implement the NDT of reinforced concrete structures.

Available in PDF, EPUB and Kindle. Book excerpt: Providing a comprehensive overview of the techniques involved in testing concrete in structures, Testing of Concrete in Structures discusses both established techniques and new methods, showing potential for future development, and documenting them with illustrative examples. Topics have been expanded where significant advances have taken place in the field, for example integrity assessment, sub-surface radar, corrosion assessment and localized dynamic response tests. This fourth edition also covers the new trends in equipment and procedures, such as the continuation of general moves to automate test methods and developments in digital technology and the growing importance of performance monitoring, and includes new and updated references to standards. The non-specialist civil engineer involved in assessment, repair or maintenance of concrete structures will find this a thorough update.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, significant developments have occurred in concrete testing and in establishing test procedures for nondestructive testing (NDT). With NDT equipment, inspectors can now determine concrete strength, pavement thickness, degree of consolidation, and curing temperatures quickly and accurately. The purpose of this guide is to present general information on several pieces of commercially available NDT equipment. The majority of the equipment covered is used for measuring the early age, in-situ, strength of the concrete at ages less than 28 days.

Available in PDF, EPUB and Kindle. Book excerpt: This book was proposed and organized as a means to present recent developments in the field of nondestructive testing of materials in civil engineering. For this reason, the articles highlighted in this editorial relate to different aspects of nondestructive testing of different materials in civil engineering—from building materials to building structures. The current trend in the development of nondestructive testing of materials in civil engineering is mainly concerned with the detection of flaws and defects in concrete elements and structures, and acoustic methods predominate in this field. As in medicine, the trend is towards designing test equipment that allows one to obtain a picture of the inside of the tested element and materials. From this point of view, interesting results with significance for building practices have been obtained
