Objective During the construction phase and the subsequent life span of advanced concrete structures costs can be significantly reduced, in particular by avoiding premature damage in the construction stage. A fundamental issue in order to achieve this is proper planning and production of the structure. With e.g. new high performance concretes it is of the utmost importance that the right quality is maintained throughout the construction period. Otherwise heavy reduction in robustness and resistance can be the result. Crucial here is the risk of early age cracking of the concrete due to restrained volume changes from temperature and shrinkage during the hardening period. An Expert System will be developed to plan and control the production of concrete structures. The Expert System will contain modules of varying simplicity and refinement which can be used in the following phases of a construction project: the predesign phaseto get rough estimates of the cost and efficiency of alternative production methods the design phasefor detailed planning of concreting (choice of materials, cooling and/or heating methods, insolation of formwork, formstripping time etc) the construction phasefor updating the influence of weather changes, fluctuation of material properties and temperatures on target crack risks the maintenance phaseto check maintenance costs and repair needs. The overall savings using these tools will be in the order of 100 MECU/year in Europe for reduced production costs. To this will be added prolonged life time and reduced maintenance costs which can be estimated to 200300 MECU per year. The project encompasses leading firms working in all of the four phases mentioned above i e consulting firms, contractors, material producers, owners and maintainers of structures as well as research institutions specialised in the different tasks of the project work. The project will contain the following main tasks: Mobilization and mangement of the project: Many partners are involved and it is important to coordinate the different tasks effectively Hydration and volume changes: Tests will be performed in order to aquire data for the modelling of properties of a number of currently used concretes Mechanical properties: Testing and modelling of mechanical properties Behaviour of structures: Computer modelling of structural behaviour Field tests: To check and improve the models of the previous tasks in full scale tests Expert system: The results of the earlier tasks will be synthesized into a robust Expert System, which can be used for planning and control of the production of high quality concrete structures Fields of science natural sciencescomputer and information sciencesartificial intelligenceexpert systems Programme(s) FP4-BRITE/EURAM 3 - Specific research and technological development programme in the field of industrial and materials technologies, 1994-1998 Topic(s) 0202 - New methodologies for product design and manufacture Call for proposal Data not available Funding Scheme CSC - Cost-sharing contracts Coordinator Scancem AB EU contribution No data Address ..,.. 100 74 Stockholm Sweden See on map Total cost No data Participants (12) Sort alphabetically Sort by EU Contribution Expand all Collapse all CESI CENTRO ELETTROTECNICO SPERIMENTALE ITALIANO GIACINTO MOTTA SPA Italy EU contribution No data Address Via Rubattino 54 MILANO See on map Total cost No data Elkem ASA Norway EU contribution No data Address --,-- 4602 Kristiansand See on map Total cost No data Enel.Hydro SpA Italy EU contribution No data Address Via Pastrengo 24068 Seriate See on map Total cost No data LULEAA UNIVERSITY OF TECHNOLOGY Sweden EU contribution No data Address Regnbagsallén, Porsön 97187 LULEA See on map Total cost No data NCC AB Sweden EU contribution No data Address Vallgatan 3 170 80 SOLNA See on map Total cost No data NORWEGIAN PUBLIC ROADS ADMNINISTRATION Norway EU contribution No data Address 92,Grenseveien 92 0033 OSLO See on map Total cost No data Norcem AS Norway EU contribution No data Address 3950 Brevik See on map Total cost No data Norges Teknisk-Naturvitenskapelige Universitet Norway EU contribution No data Address 3C,Richard Birkelandsvej 7034 Trondheim See on map Total cost No data SELMER SKANSKA AS Norway EU contribution No data Address 25,Olavsgate 25 0166 OSLO See on map Total cost No data Skanska Teknik AB Sweden EU contribution No data Address 182 25 Danderyd See on map Total cost No data TECHNISCHE UNIVERSITAET BRAUNSCHWEIG Germany EU contribution No data Address 52,Beethovenstrasse 52 38106 BRAUNSCHWEIG See on map Total cost No data Technische Universiteit Delft Netherlands EU contribution No data Address 1,Stevinweg 1 2628 BL DELFT See on map Total cost No data
