Characteristics Foam Concrete with Polypropylene Fiber and Styrofoam

Abstract

Foamed concrete is one of the concrete technology applied to the building. The advantages of foamed concrete are light and fast material on building work. The use of styrofoam and polypropylene fibers in foam concrete increases the compressive strength and flexural strength. The Styrofoam used in this study is 3 type in diameter, they are 2-3 mm, 3-4 mm, and 5-6 mm with variation of styrofoam percentage in volume is 10%, 20%, and 30%. Polypropylene fibers used 0.8 kg/m3 of foam concrete. The use of 3-4 mm in diameter styrofoam by 10% in volume and 0.8 kg/m3 polypropylene fiber had the highest compressive strength in foam concrete of 11.34 MPa. The use of 2-3 mm styrofoam by 10% in volume and 0.8 kg/m3 polypropylene fiber had the highest flexural strength in foam concrete of 4.46 MPa.
