In this paper, the results are concluded for the experiment carried on concrete using glass fiber and also different properties of concrete are found out using glass fiber. The effect on properties such as the strength of concrete, dry density, wet density, slump, split tension etc is found out by taking laboratory experiment. The concrete is prepared by using M20 grade and adding the different proportion of glass fiber from 0.5 % to 5 % weight of cement. The laboratory test is taken on concrete cubes of 15 cm size, the cylinder of 15 cm diameter and length of 30 cm and the beam of the size of 15cmXproperties are for an experimental investigation on the cm and 70 cm length. These blocks are cured in the water tank for 7 days and 28 days. It is found out that workability of concrete is reduced by enhancing the quantity of glass fiber. By taking load-deflection behavior it is found out that ductility is increased by increasing the content of glass fiber. It is found out that various parameter of concrete regarding the strengthening of concrete is enhanced by increasing the glass fiber in the concrete. There is an enhancement in the strength in the concrete. Hence it is suggested to use glass fiber in the concrete according to use of concrete.
