Abstract
Agrostone is a construction material and a substitute for concrete that used as an exterior wall and interior partition. It is composed of Magnesium Oxide Powder (MgO), Magnesium Chloride (MgCl), Bagasse, Glass fiber and Pumice. The Agrostone panel has improved damage tolerance, environmental resistance, fire resistance, and recyclability, good strength, lightweight and potential for fast processing. However, the influence of fiber orientation on tensile, compressive and bending strength of agrostone panel is not studies from the previous researchers. The aim of this experimental study is investigate the influence of different fiber orientation arrangements on tensile, compressive and bending strength of agrostone panel. The testing specimens for experimental analysis prepared by hand layup process using a mixing ratio of 1.5 kg Magnesium oxide Powder (MgO) and 2 L Magnesium Chloride (MgC1). Waste recyclable bagasse 0.15 kg, 0.065 kg Fiber Glass and 0.2 kg of Pumice based on ASTM standard D 3039/D 3039M for tensile testing, D 3410/D 3410M – 03 for Compressive testing and D 790 – 02 for Flexural testing at 0°, 45°, 90°, cross and random arrangement are prepare. From the experiment, the tensile, compressive and bending result of 0° is higher than the other arrangements that has the value of 191.87 MPa, 178 MPa and 181 MPa respectively, therefore it means 0° fiber orientation give a better strength values in general for tensile, compressive and bending loading as compare to others.
