The research has provided know how and a prototype Signal Management System (SiMaS), capable of non destructively testing concrete. In addition the SiMaS can be modified for other applications. When upgraded to a marketable standard, the instrument will offer civil engineers a new technique to assess concrete in a non-destructive environmentally friendly way. Some specific achievements and benefits are as follows: 1) Development of the SiMaS prototype instrument. The Signal Management System (SiMaS) is a unique instrument and offers exploitation potential not only in the area of concrete imaging but also in any application where signals need to be generated, controlled and resulting data stored and processed. Spin off opportunities using ultrasonic signals include listening to engines and ground imaging. Other opportunities may exist in the management of other types of signals such as magnetic or electrical and this will be pursued during exploitation. 2) Transducer design and the design programme. The transducers developed to work with the SiMaS are unique and the result of a novel design programme written specifically for the project, this design programme will be used again during the exploitation when the transducers will need to be upgraded and ruggedised for use in the field. 3) Transducer interface. The plastic interface which couples the transducers to the concrete surface allows a fast and convenient mode of operation, removing the need for mortar coupling which is slow and impractical. 4) Advanced the understanding of ultrasonic behaviour in concrete. Due to the development of the SiMaS instrument, the proposers were able to carry out ultrasonic testing on concrete which has provided the following results: a) Shown that reflection work, using ultrasonic sweeps and transducers arrays can be used to detect and possibly give the state of ducts and embedded members within concrete. b) Shown that a study of velocities and coda behaviour can be used to provide information as to the quality of concrete. c) Shown that transmission work can also be used to provide the information detailed in a) and b) above.
Hide general information
The proposed research is directed at developing a portable, concrete imaging instrumemnt for use on all types of concrete structures. The system will compromise state of the art transducer arrays, a patented transputer based instrument technology and novel processing algorithmq. It will be able to induce high frequency sonic sweeps into the concrete and detect any corresponding return signals, the recorded data will then be processed to provide a cross-section of the structure which in turn will be enhanced to provide a complete internal image giving invaluable information as to the state of the concrete highlighting and locating any internal decay and weaknesses. The major research tasks are : 1) Development of the transducer array and interfacing system (between concrete and transducer surface) to increase signal to noise. 2) Development of signal producing recording electronics to operate at the necessary high frequencies and resolution. 3) Development of suitable user interface software. 4) Development of processing algorithrns and graphical representation tools. Successful completion would provide massive savings (billions ECU for Europe alone) on concrete inspection and maintenance costs and offer structural information which could aver disasters such as structural failure which is not currently possible with existing equipment.

Starting with a prototype instrument (Signal Management System - SiMaS), developed under the CRAFT programme "Non Destructive Testing and Imaging of Concrete", this project is concerned with producing a marketable, unique ultrasonic test instrument to non destructively image concrete.The aims and objectives of the project are twofold.To upgrade to pre-production prototype standard a non destructive, concrete imaging instrument, enabling operators to obtain information as to the quality (resistance) of concrete and to detect and possibly determine the state of embedded members such as ducts and rebar within the concrete. The system will be portable, rugged, easy to use, and provide on site information for the engineer to act on. Definition phase activities (see below) will result in defining a specific target market and detailed instrument specification. To look at other applications for the underlying technology with a view to focusing the SiMaS on specific spin off market opportunities.The following activities will help in fulfilling the aims and objectives above.- Definition of technical limits of SiMaS: Technology providers to produce technical limits of SiMaS prior to market survey.- Qualitative and quantitative market study: Concentrating initially on the three partner countries, the most urgent necessities of the markets in terms of technical performance and what market volume they represent will be established, feedback will be given to technology providers to establish feasibility, include spin off possibilities.Development and on site testing at various potential user locations under different conditions the pre-production SiMaS instruments.
