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.
Fiberglass is the brainchild of Owens Corning, which originally called the product Fiberglas (with only one s). The fiberglass that's used as a building material (and not insulation) is composed of plastic that's mixed in with glass fibers, which is why it's alternately known as glass-reinforced plastic (GRP). This type of fiberglass is commonly used to make car and boat bodies, water tanks, pipes, hot tubs, and roofing. As a roofing material, fiberglass can be molded into many different shapes and designs. The most popular forms are sheets, panels, and shingles (fiberglass shingles usually contain asphalt as well).
