An Experimental Investigation on Durability Properties of Fiber Reinforced Concrete for M25 Grade

Abstract

In modern years Fibre reinforced concrete is cement based composite material has been developed. It has been successfully used in construction with its outstanding flexural tensile strength, resistance to splitting, impact resistance and outstanding permeability and frost resistance. It is a successful way to raise toughness, shock resistance and resistance to plastic shrinkage cracking of the mortar. Fibre is added as a reinforcing material possessing certain characteristic properties. Concrete is the most extensively used structural material in the world with an yearly production of over seven billion tons. For a multiplicity of reasons, much of this concrete is cracked. The reason for concrete to undergo cracking may be endorsed to structural, ecological or economic factors, but most of the cracks are formed due to the natural weakness of the material to resist tensile forces. Concrete normally shrinks and force crack when it is controlled. It is now well-known that steel fibre reinforcement offers a solution to the problem of cracking by making concrete tougher and more yielding. It has also been proved by wide investigation and field tests carried out over the past three decades. The present investigation focuses on introduction of steel, glass, carbon fibres, Polyvinyalcohol (PVA) fibres, of polypropylene fibres at the time of mixing and production improves a number of properties of concrete, particularly those related to strength, performance and durability. This review paper is an evaluative report of studies established in the recent years. It describes and gives an Experimental basis for the research.
