摘要

Non-metallic reinforcements are becoming valuable alternatives for the classical concrete reinforcements. This evolution started in the late eighties of last century. Composite materials of different type were introduced to overcome the inherent disadvantages of concrete: strength, durability, corrosion of steel rods, creep and shrinkage, flexibility and retrofitting aspects. Glass, aramid and carbon are the most popular fibre reinforcements, embedded in a pure polymer or in a polymer modified matrix. Material properties, reinforcement design, analysis and layout became important research topics, but practical applications came immediately after research, and sometimes even preceded research. Some earthquake disasters have strongly stimulated progress in composite reinforcement for concrete. The paper will deal with important material properties of FRP, on which application and durability as reinforcement is based. Implications on analysis and design are pointed out. Applications in new constructions, in rehabilitation, repair and strengthening are discussed. Information is collected from research and applications in Europe, as well as from communications with the international FRP community, especially in America and Japan, where pioneering work was done on composite reinforcement materials for concrete.
