  1. Pierre Pimienta RILEM Technical Comity TC HPB Physical Properties and behavior of High-Performance Concrete at high temperature

  2. RILEM • RILEM • International Union of Laboratories and Experts in Construction Materials, Systems and Structures • Réunion Internationale des Laboratoires et Experts des Matériaux, systèmes de construction et ouvrages • Founded: 1947 in Paris (after the war) •  Promote scientific cooperation • The mission: • Develop scientific knowledge • Encourage transfer and application

  3. RILEM • 1 200 experts • 70 countries • Technical committees (about 50) • Symposia and workshops • Publication • Materials and Structures • STARs • Recommendations

  4. RILEM technical committee TC HPB • RILEM TC HPB (2007 – 2013) • Physical Properties and behavior of High-Performance Concrete at high temperature • ACTIVE MEMBERS • 29 active members • 18 countries pays : • Austria, Australia, Belorussia, China, Finland, France, Germany, Greece, Italy, Japan, Poland, Portugal, Russia, Spain, Sweden, The Netherlands, United Kingdom, USA • BUREAU • Chairman: Pr Ulrich Schneider Pierre Pimienta (2010) • Secretary: Robert Jansson • 2 MEETINGS / year

  5. Activity of the TC • Previous RILEM TC HTC • 11 recommendations : mechanical test methods at high temperature • 1 STAR on Ordinary Concrete • State of the Art • HPC properties • Spalling • Modeling • Article on Pore pressure measurements • Physical background • Influencing parameters • Test methods for spalling • Fire safety design • Measures to prevent spalling • In connection with fib TG 4.3 • Engineering modelling • Advanced modelling • Transfertmodelling • Mechanical behaviour • Constitutive parameter relationships • Degradation reactions • Transport properties • Thermal properties • Mechanical properties • Finalization: end 2013 – Next meeting: next week in CERIB
