Properties of dispersed fibers for efficient concrete reinforcement

The question of increasing the reliability and durability reinforced concrete structures is a priority. One ways to increase strength using dispersed reinforcement. interest fiber-reinforced in Russia, as well Europe, Asia USA has increased significantly recent ten years. improvement physical mechanical properties noted depend on reinforcement parameters, such volume content fiber, characteristics reinforcement, structure matrix, etc. Authors consider various types fibers for specifically polypropylene, polyethylene, nylon, acrylic, polyester, cotton, asbestos, glass, basalt, steel, carbon. Description main advantages disadvantages each type fiber given. Comparative are presented terms density, tensile strength, modulus elasticity, elongation at fracture materials used manufacture fiber. influence crack under impact loads studied. Analytical review existing works found that it possible achieve significant axial compression, tension, tension bending, shear compared ordinary heavy concrete.
