Fiber additions to concrete offer a convenient and practical means of achieving improvements in many of the engineering properties of the material such as fracture toughness, fatigue resistance, impact resistance, and flexural strength. The concept of providing the reinforcement as an integral part of the fresh concrete mass can also provide advantages in terms of the fabrication of products and components. The fibers that are currently being investigated as reinforcement include steel, glass, and polypropylene. Other fibers such as nylon, polyethylene, rayon, and E-glass have been investigated but have been ruled out due to cost, low effectiveness or inadequate resistance to the alkaline cement environment. The application work done to date has helped to identify several factors involving preparation and properties that need to be improved upon if the full potential of this material is to be realized. (1) Users have expressed concern over the longer than normal mix preparation times required. This problem will be overcome as special equipment for handling fibers and mixing fiber reinforced concrete becomes available. (2) The formation of fiber balls or clumps during mixing continues to be a problem, especially where high fiber contents are used. Again, the use of special mixing equipment may be one way of overcoming this problem. (3) The properties of fiber reinforced concretes prepared in the field have obtained in the laboratory. This is due, in part at least, to the common practice of increasing the water content to satisfy the workability requirements of the work crew in the field. One solution to this problem would be the development of equipment and techniques to place low slump fiber reinforced concrete.
