Petroscope and modeling software

The aim is to develop optoelectronic measurement equipment and also modeling and simulation software, for the construction aggregates industry.

Introduction The aim of the PETROSCOPE project is to develop an automatic, optoelectronic testing instrument (hardware and software), to measure or 'describe' the petrographic composition, and to some extent the size and shape, of construction aggregates and other related mineral materials as part of on-site quality control. These properties are considered to be of fundamental importance, or being independent properties of the aggregates. No instrument is known of today that does analyse sand, gravel and crushed rock and other construction aggregates anywhere near to what the classical, manual 'petrographic description' test methods prescribe, such as the European test method, EN 932-3. The PETROSCOPE project aims at developing a bench-top and field-portable off-line instrument that ultimately will accomplish this task. At a later stage in the project an on-line instrument will be developed. Background. Manual, classical methods of petrographic description have become well-established and are routinely used by the construction aggregates industries for quality control, in the assessment of road aggregates and concrete aggregates, in research, etc. Quantitative petrographic description has been conducted in CANADA and the USA since the 1940s, and in some European countries for decades. In ICELAND there is a long tradition for petrographic description and a quantitative and computerized classification system was established already in 1983. A common European standard was published in 1996 (EN 932-3:1996, Tests for general properties of aggregates - Part 3: Procedure and terminology for simplified petrographic description). Traditional, manual methods, macroscopic and microscopic, require highly trained geologists and it takes considerable time to perform the test (hours, and in practice days). The precision of the method is frequently low, compared to many other test methods, especially between laboratories (reproducibility). The development of a new on-site quality control method in line with the petrographic description method, using image techniques is therefore quite relevant, although of high scientific and technical risk, a test that would be more or less automatic and take minutes or few hours to perform. Participants. Participants from the U.K., AUSTRIA, SLOVENIA, ICELAND and to some extent FINLAND will contribute to the project. The participants, PETROMODEL LTD, ICELAND; UNIVERSITY OF WEST OF ENGLAND (UWE), UK; RMC, UK; STEINBEIS TRANSFERCENTRE FOR DATA ANALYSIS AND VISUALISATION, AUSTRIA and THE SLOVENIAN NATIONAL BUILDING AND CIVIL ENGINEERING INSTITUTE (ZAG Ljubljana), contribute their specialities. PETROMODEL LTD is the main participant and has the role of managing the project, performing requirement analyses and planning industrial exploitation, working on pattern recognition, image analysis and prototype design, etc. UWE contributes to the research and testing of methods for image analysis, as well as contributing to the overall design of the instrument. RMC will contribute preparation, testing and analysis of aggregate samples as well as testing of the various versions of the PETROSCOPE prototypes. STEINBEIS TRANSFERCENTRE will work on data analysis and mathematical - statistical modelling. ZAG Ljubljana will work with preparation, testing and analyses of samples and testing of prototypes. VTT ELECTRONICS in FINLAND - Optoelectronics Department, that will be sub-contractor to PETROMODEL LTD., will do a pre-study, perform part of measurements on samples, and give recommendations regarding design of the instrument. Preliminary Project Planning Phase I - Project Management, Requirements and Exploitation: Objectives: Revision and completion of the project plan and timetable.
