Abstract

Reactive Powder Concrete (RPC) is a new technology in high strength concrete industry. Steel fibers are usually used as reinforcements in RPC mixture. In this research, steel fibers in RPC mixture are replaced by fiberglass. The volume of fibers used are 1%, 1.5%, and 2%. Curing process by steam curing in 12 hours. The concrete was tested after 28 days including compressive test, split tensile test, and flexural test. The result shown that optimal value of fiberglass added to mixture was 2% from total volume with compressive strength value at 127.38 MPa, split tensile strength at 9.844 MPa, and flexural strength at 10.36 MPa. Density of fiberglass reinforced concrete at optimum volume is 2224.3029 kg/m³it was lower than steel fibers reinforced concrete at optimum volume which has density of 2310.385 kg/m³.
