Preface

Over the past years, there has been a significant effort in the research, development
and application of fibre-reinforced concrete (FRC). This has been promoted by the
introduction of FRC in major national and international codes of structural concrete
(ACI 318, MC 2010 and the incoming EC2 among others). However, the long-term
behaviour of FRC under sustained load is still a controversial topic in both scientific
and technical forums.
One of the main issues to consider this phenomenon in codes lies in the absence
of validated and widely accepted models to predict it and standardized testing
methodologies to quantify creep in FRCs. The knowledge of the creep response on
cracked FRC elements is essential to ensure the viability of structural applications
of this material and has important consequences on structural durability and safety.
In 2014, a new technical committee was created in the frame of RILEM: the
RILEM TC 261-CCF, entitled “Creep behaviour in Cracked Sections of Fibre
Reinforced Concrete”. The TC 261-CCF is in charge of compiling information on
this topic, as well as of reaching a consensus about creep test methodologies and the
considerations for the analysis of the results. One of the proposed activities of this
TC was the organization of a RILEM workshop, with the aim of including in a
publication all collected updated researches and results on the topic.
With this objective, the FRC-CREEP 2016—International RILEM Workshop on
Creep Behaviour in Cracked Sections of Fibre Reinforced Concrete took place in
the “Universitat Politècnica de València” (Spain) during 9–10 March 2016. The
FRC-CREEP 2016 was proud to welcome 35 attendees from 16 countries, and 20
lectures were presented and discussed. Most of the active researchers in the field
took part in this event, which was a great occasion to share experiences and
establish points of interest for future studies.
The technical activity of the workshop was scheduled in four general sessions,
with an additional conference of the Honorary Chairman Ravindra Gettu and two
round tables in order to promote the discussion on two specific aspects: the “Creep
Testing Methodologies and Results interpretation” and “When creep in a cracked
section of structural FRC elements is an important issue”. This book presents the
proceedings of the workshop.

Factors Influencing Creep of Cracked
Fibre Reinforced Concrete: What We
Think We Know & What We Do
Not Know
Ravindra Gettu, Raúl Zerbino and Sujatha Jose

Abstract The significance of the creep behaviour of fibre reinforced concrete
(FRC) in the cracked state is a matter of debate. As FRC in service could be in the
cracked state, the serviceability and failure will depend on the stability of the
cracks, and the alteration of the capacity to transfer stresses. Based on the present
knowledge, this paper discusses factors influencing the creep of cracked FRC to
facilitate further discussions. Effects of load, temperature and humidity, and the
importance of progressive debonding and pull-out, creep of the fibres and crack
propagation under sustained loading have been discussed for steel and polymer
fibres.

1 Introduction
Over the past few decades, fibres have been incorporated in concrete in many
applications, such as pavements, slabs on grade, tunnel linings and structural elements along with conventional reinforcement, to improve the service life and failure
mode of structures. Since the serviceability depends on the stability of cracks and
capacity to transfer sustained stresses, the creep behaviour of cracked fibre reinforced concrete (FRC) is significant. The fib Model Code 2010 raises concerns
about the long-term performance of concrete reinforced with fibres that could be
affected by creep.
