Experimental Study on Mechanical and Durability Properties of Glass and Polypropylene Fiber Reinforced Concrete

The aim of the study is to validate the effect of glass fiber and polypropylene fiber on improving the mechanical and durability properties of concrete. In this regard, glass fiber, polypropylene fiber and hybrid fiber were added to concrete, respectively. This paper conducted the compressive and bending flexural tests to confirm that the fiber enhances the mechanical properties of concrete. In order to evaluate the durability of fiber reinforced concrete, the rapid chloride migration test and rapid chloride penetration test were carried out. The comparisons of experimental results illustrate that the hybrid fiber reinforced concrete has the most significant effect on the concrete properties improvements. Moreover, comparing with the glass fiber reinforced concrete, the polypropylene fiber reinforced concrete plays a better performance on mechanical and durability properties.
