Focus Group 4: Fibres For Concrete
Ongoing projects
The “Fibres for Concrete” Focus Group is working on an alternative test method designed to complement EN 14488-3, known as 'the three-point bending test on square panel with notch.' Our dedicated members are actively championing its integration into the EN Standard, enhancing industry testing practices.
Additionally, EFNARC has put forth a comprehensive testing procedure that specifies a method for assessing the creep behavior of both pre-cracked and non-pre-cracked slab specimens under constant load.
These initiatives exemplify our commitment to advancing industry standards and methodologies.
Past accomplishments
EFNARC played a pivotal role in the development of European standards, demonstrating its leadership within the industry, taking charge of the relevant CEN Technical Committee by providing both the Convenor and Secretary.
The CEN committee, known as TC 104 WG11, embarked on its mission in February 2001 and made remarkable strides in shaping the standards essential to fulfil the European Commission's Mandate. This effort culminated in the publication of the following pivotal standards:
EN 14889-1:2006: Establishing definitions, specifications, and conformity criteria for steel fibres used in concrete.
EN 14889-2:2006: Defining specifications and conformity requirements for polymer fibres utilized in concrete.
EN 14845-1:2007: Outlining reference concretes for testing fibres in concrete.
EN 14845-2:2006: Detailing the effects of fibres on concrete through comprehensive test methods.
These accomplishments underscore EFNARC's enduring commitment to advancing industry standards and methodologies.
Future Plans
Continued Standard Development: Work towards the development of additional standards or revisions to existing ones that address emerging materials and technologies in the field of fibres for concrete.
Research and Innovation: Foster collaboration with research institutions and industry partners to stay at the forefront of advancements in fibre technology and their applications in concrete.
Global Harmonization: Collaborate with international counterparts to align European standards with global standards, promoting consistency and interoperability in the industry.
Alignment with Environmental Goals: Explore ways to align fibre-reinforced concrete practices with environmental sustainability goals, such as reducing waste and energy consumption.
Collaboration Opportunities
Mechanisms of FRSC: We aim to elucidate the fundamental mechanisms that empower fibre-reinforced sprayed concrete (FRSC) to function effectively as a support lining in various construction applications.
Types of Fibres: We provide a comprehensive overview of the diverse range of fibres available for FRSC. Our goal is to detail and distinguish their unique properties, ensuring that industry professionals can make informed choices when selecting fibres for specific projects.
Testing Methods and Interpretation: We offer insights into the various testing methods associated with FRSC and guide professionals on how to interpret the results in alignment with the specifications outlined in contractual specifications such as MC 2010.
Enhancing Specifications: We are committed to elevating the quality of specifications for FRSC to meet the performance criteria of every project. Our focus is on tailoring specifications to the unique requirements of each project, optimizing the use of fibre-reinforced sprayed concrete.
Quality Control Process: Improving the quality control process is central to our mission. We work to establish robust quality control protocols that enhance the consistency and reliability of FRSC applications.
Standard Specification Examples: In addition, we aim to provide industry professionals with standardized specification examples for various applications, including temporary and permanent linings. These examples serve as valuable templates, simplifying the specification process and ensuring the desired performance outcomes.
