FRCC: design and application in Japan

摘要

The development of concrete and cement composites containing fibre reinforcement to improve tensile load-deformation behaviour has resulted in three distinct classes of materials. These are conventional fibre-reinforced concrete (FRC) with tension softening response, ultrahigh strength fibre-reinforced concrete (UFC) with increased compressive/tensile strength and high performance fibre-reinforced cement composites (HPFRCC) with strain hardening and multiple cracking characteristics. This paper introduces and compares Japan's recommendations on the design, production and application of these fibre-reinforced concrete types with the aim of outlining distinctive and common characteristics of the different classes of cement composite materials. Examples of structural applications for HPFRCC and UFC are also described.
