Experimental Relationship Between Splitting Tensile Strength and Compressive Strength of GFRC and PFRC

The use of fiber reinforced concretes (FRC) has increase in building structures because the reinforced fibers in concrete improve the toughness, flexural strength, tensile strength, impact strength as well as the failure mode of the concrete. The goal of this investigation is to provide an experimental inquiry into the relationship between tensile strength and compressive strength of glass fiber reinforced concrete (GFRC) and polypropylene fiber reinforced concrete (PFRC). The splitting tensile strength and a compressive strength of GFRC and PFRC at 7, 28 and 90 days were used. The results showed: that the splitting tensile strength of GFRC and PFRC ranged from 9% to 13% of its compressive strength; the addition of glass and polypropylene fibers increases the splitting strength by 20-50%; and a simple 0.5 power relationship between the splitting tensile strength and the compressive strength of GFRC and PFRC can be successfully used to estimate the splitting tensile strength.
