Foamed Lightweight Concrete Tech Using Galvalum Az 150 Fiber

Lightweight foamed concrete has a compressive strength of between 1 MPa to 15 MPa [1] and normally is at grade of non structural concrete. A method to improve its tensile strength, compressive strength and modulus of elasticity is conducted by adding fibers i.e. Galvalum. This research aims at determining the effect of adding Galvalum fiber to above properties of lightweight foamed concrete. The research resulted a concrete with specific gravity less than 1900 kg/m3, compressive strength increased by 34.09%, tensile strength increased by 47.37% and modulus of elasticity increased by 25.81% so that it is categorized as structural concrete.
