Categorization of Fibers and their Influence on Concrete Properties

Abstract

Incorporation of the different types of fibers in the concrete composite has become a conventional approach in the recent era. The culminating enhancement of various properties of the cement and concrete composite by the instigation of the fibers and their feasibility to the various environmental conditions make them stand out in the present scenario. Furthermore, the hybrid fibers in various combinations have a synergetic effect which causes the advancement of two more parameters of the concrete composites. This paper lines up the transformations in the physical, chemical and the mechanical properties of fiber reinforced concrete. This provides the abbreviation of the classification of fibers and the impact of mono fibers and hybrid fibers as well in the concrete composites. Thus the different literature reviews throw light on the necessity, choosing the right fiber and their consecutive effects on the type of concrete composite used. Steel fibers and polypropylene fibers were noted to improve the mechanical strength to an extend whereas glass and carbon fibers tend to have the same effect in lower level which had also become a hazardous one owing to the various chemical reactions. Though the natural fibers have good durable properties, it is used less due to its degradable nature
