Book Description
This report describes the design and construction of a prototype instrument for location of steel dowel bars and tie bars in highway concrete. The instrument consists of a non-metallic (wooden) wheeled platform which carries a commercially available metal detector known as a covermeter, specially modified for this project. The covermeter is designed to be held in the hand and swept over a concrete wall or road, displaying the distance to steel within the concrete. The modified covermeter, mounted on the platform together with a notebook computer, outputs a serial data stream which is converted by the included software into information about the location and orientation of an array of dowel bars.

Book Description
This Proceedings contains the papers of the fib Symposium “CONCRETE Innovations in Materials, Design and Structures”, which was held in May 2019 in Kraków, Poland. This annual symposium was co-organised by the Cracow University of Technology. The topics covered include Analysis and Design, Sustainability, Durability, Structures, Materials, and Prefabrication. The fib, Fédération internationale du béton, is a not-for-profit association formed by 45 national member groups and approximately 1000 corporate and individual members. The fib’s mission is to develop at an international level the study of scientific and practical matters capable of advancing the technical, economic, aesthetic and environmental performance of concrete construction. The fib, was formed in 1998 by the merger of the Euro-International Committee for Concrete (the CEB) and the International Federation for Prestressing (the FIP). These predecessor organizations existed independently since 1953 and 1952, respectively.
