Fibre Reinforced Concrete (FRC) is a composite material with a cementitious matrix and a discontinuous reinforcement (the fibre) that is made of metal, glass, or other synthetic or natural materials. While ongoing research is yielding better knowledge on the properties of these composites, new applications are being developed: pre-cast tunnel segments, foundations, piles, prefabricated structures, building components, beam-column nodes, structural repairs, etc.

The sixth RILEM Symposium on FRC (BEFIB 2004) follows the first four Symposia held in the UK and the fifth one held in France. It aims to establish the boundary of current knowledge on FRC, and compare the status of design procedures and codes in different countries.

The Symposium also offers an opportunity to gather researchers, academics, designers, professional engineers, heads of construction companies and concrete manufacturing companies, architects and project supervisors in order to answer the ongoing question: “What scientific, technical and technological knowledge, for what industrial objectives?”

Contributions concern the following broad areas:

* mechanical, physic-chemical properties
* mix design and placement
* durability and extreme environment conditions
* modelling and design methods
* structural and industrial applications
* special loading
* special concrete
