The dissertation describes the development and validation of a new instrument based on Time Domain Reflectometry (TDR) for measuring properties of fresh and early age concrete. It provides an alternative to traditional quality control methods that rely heavily on the slump value and compressive strength that do not always produce durable concrete. Work in the first stage focused on the design and development of a prototype sensor system for use on fresh and early age concrete. An experimental program systematically evaluated the sensor system's ability to measure the performance properties of concrete. The program tested several representative types of concrete specimens used in highway pavement, bridges, and industrial and residential structures. TDR signals were collected from concrete specimens subjected to different curing conditions, including early freezing, and the results were correlated with data obtained by standard test methods. The results indicated that the TDR sensor system can reliably measure or estimate concrete properties, such as free water content, density, air void content, initial and final setting times, and mechanical strength. The technology was found not only suitable to measure the physical and electrical properties of materials at common temperature but also works non-destructively under freezing-thawing cycles.

Download and read online ebook Non-destructive Testing of Materials in Civil Engineering write by Krzysztof Schabowicz. This book was released on 2019-11-19. Non-destructive Testing of Materials in Civil Engineering available in PDF, EPUB and Kindle. 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
