Analysis of the RRT Results,ed, environmental conditions, pre-crack level or creep index and mechanical performance were analysed among all the RRT participants. In addition, the main methodologies were independently analysed to search significances between the participant procedures. Analysis of the described procedures, test

General Procedure of Creep Test,eep test on square panels based on EN 14488-5 and flexure creep test on round panels based on ASTM C1550. An overview of these four main methodologies is described in the following subsections. All the procedures defined by each participant were grouped by methodology and compared in terms of configuration, equipment and measurement devices.

cacophony

Round-Robin Test Results,racking and creep stages together with the evolution in time of delayed deformation figures are presented and analysed for each participant laboratory. The RRT creep database is available open access to the scientific community to improve the global knowledge in the long-term deformations of the cracked FRC specimens.

Introduction and Background, of this RRT. The main objectives as well as the limitations of the scope of the RRT are explained. The structure of the book is presented to provide a first overview of the book content. Finally, information about institutions involved as well as geographic distribution of RRT participants and number of specimens tested in the RRT is provided.

Round-Robin Test Program and Execution, per day to avoid as much as possible any variation due to production. A total of 451 FRC specimens were cast, demould, numbered and arranged in pallets to be shipped to the respective laboratories. The distribution of specimens among the participants is presented.

Data and Parameter Definition,eters and variables of the RRT procedure were previously established by the participants to perform similar creep test procedures and therefore obtain comparable results. The arguments agreements of parameters such as the reference pre-crack opening level, the reference residual strength or the creep index are entirely described.

Although different creep test methodologies have been developed in recent years, the absence of a standardised creep methodology hindered general comparisons. Therefore, the RILEM TC 261-CCF launched an ambitious international RRT prog
