Engineering Properties of Carbon Fiber and Glass Fiber Reinforced Recycled Polymer Concrete

Abstract

This study was performed to evaluate engineering properties of carbon and glass fiber reinforced recycled polymer concrete. Fiber reinforced recycledpolymer concrete were used recycled aggregate as coarse aggregate, natural aggregate as fine aggregate, CaCO3 as filler, unsaturated polyester resin asbinder, and carbon and glass fiber as fibers. The compressive and flexural strength of carbon fiber reinforced recycled polymer concrete were in the rangeof 68~81.5 MPa and 19.1~21.5 MPa at the curing 7days. Also, the compressive and flexural strength of glass fiber reinforced recycled polymer concretewere in the range of 69.4~85.1 MPa and 19~20.1 MPa at the curing 7days. Abrasion ratio of carbon and glass fiber reinforced recycled polymer concretewere decreased 21.6 % and 11.6 % by fiber content 0.9 %, respectively. After impact resistance test, drop numbers of initial and final fracture wereincreased with increase of fiber contents. Accordingly, carbon fiber and glass fiber reinforced recycled polymer concrete will greatly improve thehydraulic structures, underground utilities and agricultural structures.
