A coordinated effort was required to improve the knowledge on long-term behaviour of cracked FRC sections and assess the different testing methodologies available. The RILEM Technical Committee 261-CCF launched in 2015 the round-robin test (RRT) on creep behaviour in cracked sections of FRC program. This chapter includes the introduction and background to understand the realisation 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.}, language = {en} } @incollection{LlanoTorreSernaCavalaroetal., author = {Llano-Torre, Aitor and Serna, Pedro and Cavalaro, Sergio H.

The same concrete matrix was used to design two different FRC mixes with steel (SFRC) and macro-synthetic (SyFRC) fibres and to produce 451 FRC specimens. The use of 124 specimens for creep tests for one year following four main methodologies provided a huge database with more than 15,000 data. The main statements and conclusions derived from the RRT database analysis are summarised in this section. Note that the conclusions derived from this RRT are limited to the ranges of parameters, procedures and variables considered here and should not be extrapolated to other cases.}, language = {en} }
