Characteristics of Fiber Reinforced Recycled Lightweight Polymer Concrete

Recently, with the rapid development of super high building and larger span concrete structure, polymer concrete can make lightweight and high strength, and use of fiber is required to improve toughness. This study is performed to examine characteristics of polypropylene fiber reinforced recycled lightweight polymer concrete(PFLP) and steel fiber reinforced recycled lightweight polymer concrete(SFLP) for fiber content. The tests are carried out at 20 +/- 1 degrees C and 60 +/- 2% relative humidity. At 7 days of curing, their unit weight, compressive strength, flexural strength and pulse velocity ranged between 1.848 similar to 1.972 kg/m(3), 40 13 similar to 52.75 MPa, 14.25 similar to 18.10 MPa and 3,380 similar to 3,560 m/s, respectively.
