INTRODUCTION
1.1. Background Information
Today in construction industry has got top priority for sustainability. Concrete is man-made product which is the most commonly used in the construction industry in the world. To decrease/ control of cracking is especially more important normally first hours after pouring of concrete. polypropylene Fibers in concrete improving the mechanical properties. Fibers effectively restrict the propagation of contraction cracks through dispersing the internal stresses. more amount of fiber material used in the concrete to restrict the spreading of the cracks. The performance of the fiber-reinforced concrete depends on interaction between the cement matrix and the fibers, which depends on the adhesion and the friction forces. Due to their low surface energy and chemical structure, show extremely low wet ability and poor adhesion with the cementitious matrix. Looking for aggregates for concrete or any construction activity and to dispose of the waste from various industries is the present concern. In this study the recycled polypropylene fibers 12 mm were used in concrete mix for comparative study of compressive and flexural strength of the concrete and to reduces the shrinkage cracks on the surface of the pavement concrete. use of polypropylene fiber as a industrial waste in the construction industry and to maintain environmental balance.
The productive use of waste material represents a means of improving some of the problems of solid waste management. It helps to save and sustain natural resources that are not restocked. The use of polypropylene fiber in concrete is a relatively recent concept. One of the important reviews on the use of waste polypropylene fiber in concrete focused on the advantages and financial benefits of polypropylene fiber, besides their physical and mechanical properties.
