This book was released on 2017 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-destructive tests (NDT) are commonly used in construction to evaluate concrete quality for both existing structures and during construction. The reliability of these tests have been questioned. This thesis is concerned with evaluating concrete strength and durability using different non-destructive tests (NDT). Also, it focuses on applying different combination of NDT to predict the concrete strength and durability using regression models. The main objective of the study was to investigate how to improve the reliability of nondestructive tests NDT to evaluate the concrete quality by combining more than one NDT test for concrete mixtures commonly used in Al Ain city, United Arab Emirates. The concrete quality was evaluated by measuring strength and durability. Different tests were conducted like ultrasonic pulse velocity (UPV), surface rebound number (Rn) and core test for predicting the concrete strength, while surface resistivity (SR) was used to predict the durability. NDT were combined using regression models to predict the concrete strength and durability. The study developed several models to combine UPV and Rn to predict compressive strength based on individual results obtained from each test, choose the best model, and compare the predicted values to actual results. Several models were developed to combine UPV and SR to predict concrete durability assessed by the rapid chloride permeability test (RCPT). The developed models were examined to choose the superior one and evaluate the predicted values to the actual results. The developed models are expected to improve the reliability of predicting the concrete quality, strength and durability for concrete structures in Al Ain city. Also, it is expected to improve quality control in concrete production by using fast, cost-efficient and reliable NDT method.

Download or read book Non-destructive Testing of Materials in Civil Engineering written by Krzysztof Schabowicz and published by MDPI. This book was released on 2019-11-19 with total page 448 pages. 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

Download or read book Non-destructive Testing and Evaluation of Civil Engineering Structures written by Jean-Paul Balayssac and published by Elsevier. This book was released on 2017-11-22 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The non-destructive evaluation of civil engineering structures in reinforced concrete is becoming an increasingly important issue in this field of engineering. This book proposes innovative ways to deal with this problem, through the characterization of concrete durability indicators by the use of non-destructive techniques. It presents the description of the various non-destructive techniques and their combination for the evaluation of indicators. The processing of data issued from the combination of NDE methods is also illustrated through examples of data fusion methods. The identification of conversion models linking observables, obtained from non-destructive measurements, to concrete durability indicators, as well as the consideration of different sources of variability in the assessment process, are also described. An analysis of in situ applications is carried out in order to highlight the practical aspects of the methodology. At the end of the book the authors provide a methodological guide detailing the proposed non-destructive evaluation methodology of concrete indicators. - Presents the latest developments performed in the community of NDT on different aspects - Provides a methodology developed in laboratory and transferred onsite for the evaluation of concrete properties which are not usually addressed by NDT methods - Includes the use of data fusion for merging the measurements provided by several NDT methods - Includes examples of current and potential applications

Book Synopsis Non-Destructive In Situ Strength Assessment of Concrete by : Denys Breysse
Download or read book Non-Destructive In Situ Strength Assessment of Concrete written by Denys Breysse and published by Springer Nature. This book was released on 2021-04-27 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents the work of the RILEM Technical Committee 249-ISC. Addressing the effective application of new recommendations for non-destructive in situ strength assessment of concrete, it provides information about the different steps of the investigation and processing of test results, until the delivery of strength estimates, and includes tables giving the minimum required number of cores in a variety of situations as well as several examples of how the recommendations can be used in practice. The book explores a topic which is of major importance, i.e. the assessment of concrete compressive strength in existing structures. This property (both mean and standard deviation) is a key input in many cases, such as the reinforcement of structures, the safety checking, the extension of service life. As the new RILEM recommendations imply a deep revision (and improvement) of field practice, the book is intended for managers of structures, structural engineers and specialists of NDT that have to answer these issues. More widely, it will benefit engineers and students who are interested in NDT and in the safety analysis of structures.

Book Synopsis Infrared Thermography Recent Advances and Future Trends by : Carosena Meola
Download or read book Infrared Thermography Recent Advances and Future Trends written by Carosena Meola and published by Bentham Science Publishers. This book was released on 2012-08-03 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared thermography (IRT) is a non-contact, non-invasive methodology which allows for detection of thermal energy that is radiated from objects in the infrared band of the electromagnetic spectrum, for conversion of such energy into a visible image (such as a surface temperature map). This feature represents a great potential to be exploited in a vast variety of fields from aerospace to civil engineering, to medicine, to agriculture, etc. However, IRT is still not adequately enclosed in industrial instrumentation and there are still potential users who might benefit from the use of such a technique and who are not aware of their existence. This e-book conveys information about basic IRT theory, infrared detectors, signal digitalization and applications of infrared thermography in many fields such as medicine, foodstuff conservation, fluid-dynamics, architecture, anthropology, condition monitoring, non destructive testing and evaluation of materials and structures. The volume promotes an exchange of information between the academic world and industry, and shares methodologies which were independently developed and applied in specific disciplines.
