Performance of Concrete by using Glass Fiber

Glass fibre reinforced concrete is recent introduction in the field of construction .concrete is a most important and widely used material is called upon to possess very high strength and sufficient workability properties .at the same time concrete is brittle and weak in tension .to improve the properties of concrete, material was named alkali resistant glass fibre. reinforced concrete in the present view the alkali resistant glass fibre has been used .in the present experiment investigation the alkali resistant glass fibre has been used to study the effect on compressive ,split tensile and flexural strength on m35 grade of concrete .ordinary concrete possess very low tensile strength ,limited ductility and little resistance to cracking .internal crack in concrete structure are inherently present and its poor tensile strength is due to propagation of such micro cracks. Glass fibre when added in certain properties well as crack resistance, ductility, as flexural strength and toughness .mainly the studies and research in fibre reinforced concrete has been devoted to steel fibre. In recent time, glass fibre have also become available, which are free from corrosion problem associated with steel fibre. the experiment investigation concluded glass fibre with structural concrete alkali resistant glass fibre specific gravity is 2.68 ,elasticity modules is 72gpa,tensile strength is 1700mpa,diameter is 14 micron, length is 12 mm and number of fibre 235 million /kg. Glass fibre reinforced concrete has advantage of being light weight and these by reducing the overall cost of construction there by bringing economy construction.
