Abstract: The most of the research over the world are carried out to develop high performance concretes by using fibers and other admixtures in concrete up to certain proportions. In the view of the global sustainable developments, it is imperative that fibers like glass, carbon, polypropylene and aramid fibers provide improvements in compressive strength, tensile strength, fatigue characteristics, durability, shrinkage characteristics, impact, cavitations, erosion resistance and serviceability of concrete. Fibers impart energy absorption, toughness and impact resistance properties to fiber reinforced concrete material and these characteristics in turn improve the fracture and fatigue properties of fiber reinforced concrete research in glass fiber reinforced concrete resulted in the development of an alkali resistance fibers high dispersion that improved long term durability. This system is named as alkali resistance glass fiber reinforced concrete. The present study investigates the effect of alkali resistance glass fibers in addition of 0.5% and 0.1% on compressive strength of M20 grades of concrete. Total 27 samples were prepared under this study to determine the compressive strength of different different proportions of glass fibers in concrete. The results is found for 0%, 0.5% and 1% glass fibers in concrete about 18.59 MPa, 20.81 MPa and 21.5 MPa after 7 days, 19.6 MPa, 22.22 MPa, 22.7 MPa after 14 days and 20.59 MPa, 24.4 MPa and 25.3 MPa respectively.
