Concrete is widely used in various structure. To improve the performance of development of concrete, essential additive both chemical and mineral material were used. To increase the strength of concrete using Glass Fiber High Strength Concrete (GFHSC) in India, this is produced with locally available material. Fly ash is a mineral material which is obtained from thermal power plant. This paper of experimental research to determine the properties of GFHSC with fly ash contain. Cement is widely used in construction but recently concrete cement is replaced by admixture such as fly ash, silica fume, quarry dust etc and glass fiber is mixed to improve the high strength of concrete and to reduce creep and shrinkage. In paper glass fiber used in different volume with 5%, 10% and 15% replacement of cement by fly ash used in concrete mix of M-20 and M-30 grades. A superplastizier (0.5% by weight of cement) is used in both fly ash and glass fiber to reduced its workability. the ultrapulse velocity and split tensile strength test is performed for 7 and 28 days.
