EFFECT OF ADDITION OF DIFFERENT TYPE OF FIBERS ON MECHANICAL PROPERTIES OF CONCRETE-A REVIEW

Abstract

Concrete is a brittle material when it is subjected to normal stresses and impact loads, where tensile strength is relatively low compared to compressive strength. Use of uninterrupted reinforcement in concrete enhances strength and ductility, but involves deliberate placement and labour acquisition. In this research the effect of addition of different types of fibres on mechanical properties of concrete was studied. The concept of using fibres to amend the characteristics of construction materials is very old. When concrete cracks, and arbitrarily oriented fibres start working, arrest cracks establishment and extension, and thus amend strength and ductility. Reinforced fiber concrete symbolizes the current leaning to enforce more effective crack-resistant concrete. The geometric size and modulus of fibers are the main factors influence the mechanical performance of fiber reinforced concrete. The result says that the usage of fibers in concrete mix increases the compressive strength, flexural strength, split tensile strength, ductility and impact strength.
