The world's biomes. Biomes are defined as the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment (Campbell 1996). The importance of biomes cannot be overestimated.
Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity.he concept of using fibers as reinforcement is not new. Fibers have been used as reinforcement since ancient times. Historically, horsehair was used in mortar and straw in mud bricks. In the 1900s, asbestos fibers were used in concrete.
1 One of the most common and familiar composite is fiberglass, in which small glass fiber are embedded within a polymeric material (normally an epoxy or polyester). 2  The glass fiber is relatively strong and stiff (but also brittle), whereas the polymer is ductile (but also weak and flexible).
