Recommendation of RILEM TC 200-HTC: Mechanical concrete properties at high temperatures—modelling and application

Part 11: Relaxation
  • Ulrich Schneider
Original Paper

Abstract

Mechanical concrete properties at high temperatures depend on many parameters. The main parameters are the specimen type and the test conditions. The report describes the test parameters and test procedures for relaxation tests in the range of 20 to 750°C.

Résumé

Les propriétés mécaniques de béton aux hautes températures dépendent beaucoup aux des paramétres conditionnels. Les paramétres principales sont le type des épreuves et les conditions techniques du essai. Le rapport décrit les paramétres et les conditions techniques du essai pour les essais de la relaxation dans une gamme de température de 20 à 750°C.
