USE OF VERY HIGH PERFORMANCE CONCRETE ON SITE

摘要

The erection of the exhaust cooling tower of French CIVAUX nuclear power plant has given the opportunity to test the use of B.S.I. (Beton Special Industriel) 150 Mpa (21.755 ksi) concrete, cast under on-site conditions. This experimentation has shown the feasibility of building VHPC (very high performance concrete) structures on site using conventional processes and methods. 4 beams, 14 meters long, supporting a heat exchanger, were cast without vibration. This very high performance concrete is used as a structural component without either conventional reinforcing steel or prestressing tendons. A full scale test with deflection measurements has confirmed its excellent behaviour.
