POLYPROPYLENE OR STEEL MESH FOR REINFORCEMENT?

This article attempts to provide an understanding of polypropylene fibers and steel mesh which could serve as a guide in selecting reinforcement. Steel reinforcement is most useful in reinforcing the material after cracking has occurred. Since concrete is weak in tension and the tensile value of concrete may be lost due to drying shrinkage, structural designs use reinforcing steel in areas where structured loads will generate tensile forces. This steel is structural reinforcement and is commonly called primary or main reinforcement. Non-structural or intrinsic cracks such as plastic shrinkage cracks can be reduced by using polypropylene fibers such as Fiber-mesh. This reduction will better enable the concrete to better develop its optimum integrity. Other benefits of polypropylene fibers as a secondary reinforcement in hardened concrete include protection against impact forces, against abrasion, and against corrosion.
