Concrete undergoes dynamic loading and rigorous environmental conditions. The development of shrinkage cracks in plain cement concrete is a major problem. To overcome this problem sometimes the addition of synthetic fiber to the concrete mix is beneficial. Synthetic Fiber Reinforced Concrete is increasingly being recognized as a favorable substitute for unsustainable inputs. These fibers are made from synthesized polymers of small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum-based chemicals or petrochemicals. These materials are polymerized into a chemical that bonds two adjacent carbon atoms. Differing chemical compounds are used to produce different types of synthetic fibers. It accounts for about half of all fiber usage, with applications in every field of fiber and textile technology
