Physical & mechanical properties of fiber reinforced metakaolin-based geopolymer concrete
Highlights Fiber reinforced Geopolymer Concrete (GPC) is a novel and advanced type of GPC. PP, 2-part PP, 4-part polyolefin fibers & 0.15, 0.2, 0.25% volume content is studied. Fibers improve compressive, tensile and flexural strengths of GPC composites. Fibers reduce specific density and water absorption of GPC composites. Fibers show negligible effect on resistance of GPC mixes to elevated temperatures.
Abstract Research on fiber reinforced Geopolymer Concrete (GPC), as a novel type of GPC with enhanced ductility characteristics has gained interest. In this paper, mechanical and physical properties of GPC reinforced with different fiber types (Polypropylene or PP, 2-part PP, 4-part polyolefin) and volume content (0.15, 0.2 and 0.25%) is investigated. Initially, an experimental campaign on the various effective parameters of metakaolin-based GPC is performed to find the optimal mix design. The results displayed the beneficial influence of fibers in improving compressive, tensile and flexural strengths, reduction of specific density and water absorption, and negligible effect on resistance to elevated temperatures.
