Abstract/Summary

The purpose of this paper is to compare two common polymers of the construction industry and determine if there are benefits of using them in concrete application to increase overall strength. The goal of the project is to complete a full experiment, utilizing concrete cylinders and beams to test the compressive and tensile properties of fiberglass and carbon fiber. This paper provides data from the experimentation of the compressive and tensile tests of carbon fiber and fiberglass to prove that these polymers are superior and aid in overall concrete strength. The experiment proved that carbon fiber is superior to fiberglass, netting an increase of 5,666 psi in the cylinder compression test, and an increase of 1,975 pounds of load in the rebar-reinforced beam tensile test. While both fibers increased the strength in the beam tensile test compared to the control beam, only the carbon fiber cylinder gave an increase of strength compared to the control beam.
