A Review on Mechanical Behavior of Various Strength And Flexure Parameters on Hardened High Strength Fiber Reinforced Concrete (HSFRC)

Abstract

This Review paper presents the Study for effective use of different shapes Steel Fibre for enhancing Flexural capacity of High Strength Concrete Beam, Along with Compressive & tensile strength. The flexural tensile strength or modulus of rupture (MOR) of concrete generally referred to tensile strength is an important parameter for determining deflection, minimum flexural reinforcement and to compute the on-set of visible cracks in a concrete structure under flexure. It is generally agreed that the theoretical compressive strength was approximately ten times the tensile strength, which implies a fixed relation between these two values. The ratio of tensile to compressive strengths is lower while the compressive strength increases to higher level. The Study of High strength concrete(HSC) from past few decades focused on premature deterioration of reinforced concrete structures, flexural strength, tensile strength, fatigue strength which exposed to severe environmental actions and acted by mechanical loading, this issue has been became a serious problem, with today’s normal and HSC structures. The use of steel fibers in HSC is generally used for enhancing the flexural strength and other parameters. In recent years, considerable works has been performed on steel fibres reinforced concrete to increase the load carrying capacity of concretes structural members and enhancing flexural strength. It is concluded that Fibres substantially reduce the brittleness of concrete and improve its engineering properties, such as tensile, flexural, impact resistance, fatigue, load bearing capacity after cracking and toughness etc.
