STUDY OF MECHANICAL PROPERTIES OF HIGH STRENGTH CONCRETE BY USING STEEL FIBER – A REVIEW

Concrete is the mostly used construction material in the world but there is a disadvantage of concrete that it is week in tension. This results to the brittleness of concrete. This property is not desirable for any kind of construction so there is requirement of tensile reinforce. in concrete in the previous time steel is used as tensile reinforcement in the tensile zone of concrete this steel is specifically designed but in case of fibres, fibres are short thin and uniformly or randomly distributing in the concrete steel fibres are basically defined as fibres that are short in length and having different cross sections according to the length and diameter (Aspect ratio) from 20 to 100 these are of small size due to which they can be easily distributed in the fresh controlled mix. this random distribution shows loss of efficiency but the addition of fibres in concrete shows improvement in toughness and tensile properties of concrete with the help of resistance to cracking, with the help of different researches it is found that there is improvement in the properties of concrete and further development of steel fibre reinforced concrete is going on since last three decades this paper presents review of mechanical property of steel fibre reinforced concrete its benefits and its uses.
