Abstract
In conventional concrete, micro-cracks develop before structure is loaded because of drying shrinkage and other causes of volume change. When the structure is loaded, the micro cracks open up and propagate because of development of such micro-cracks, results in inelastic deformation in concrete. PP Fiber reinforced concrete (PPFRC) is cementing concrete reinforced mixture with more or less randomly distributed small fibers. In the PP FRC, a numbers of small fibers are dispersed and distributed randomly in the concrete at the time of mixing, and thus improve concrete properties in all directions. The fibers help to transfer load to the internal micro cracks. PP FRC is cement based composite material that has been developed in recent years. It has been successfully used in construction with its excellent flexural-tensile strength, resistance to spitting, impact resistance and excellent permeability and frost resistance. It is an effective way to increase toughness, shock resistance and resistance to plastic shrinkage cracking of the mortar. These fibers have many benefits. Durability of the concrete is improved to reduce in the crack widths. Polypropylene and Nylon fibers are used to improve the impact resistance. Many developments have been made in the fiber reinforced concrete. In this study, the results of the Strength properties of Polypropylene fiber reinforced concrete are to present. The compressive strength, splitting tensile strength of concrete samples made with different fibers amounts varies from 0%,0.5%,1% 1.5% and 2.0% are to study.
