The use of fly ash as an addictive material, as some replacement of cement. The most important benefit is reduced permeability to water and chemicals. FRC has found many applications in civil engineering field. Based on the laboratory experiment on fiber reinforced concrete (FRC), cube, cylinders and beam specimens have been designed with Glass fiber reinforced concrete (GFRC). For concrete mixes 43 grade of ordinary Portland cement and class F type fly ash is used Water/ cement ratio 0.5%. Concrete cubes are casted with varying percentage of Glass fiber by 0.5%, 1%, 1.5%, 2% by weight of cement of 12mm cut length where used with admixture. And fly ash replacement 25% fly ash is used. The size of cubes is 150mm x 150mm x150mm. Water/cement ratio 0.5%. Test is carried out after 7 days, 14 days and 28 days of curing period. The tests conducted on concrete specimens are compressive strength, Split tensile strength, Flexural strength. Comparing the result of (FRC) with plain M20 grade concrete, this paper validated the positive effect of different fibers with percentage increase in compression and splitting improvement of specimen at 7, 14 and 28 days, analyzed the sensitivity of addition of fibers to concrete with different strength.
