The Relation between Density and Flexural Strength of Geopolymer Based Ceramic with Addition of Ultra High Molecular Weight Polyethylene (UHMWPE) for Lightweight Ceramics

Abstract:

Geopolymer are being considered for a variety of application including formation of ceramics. The addition of Ultra High Molecular Weight Polyethylene as binder in geopolymer based ceramic is purposely to enhance the strength and toughness of the ceramic materials. This paper aims to study the relation of density and flexural strength of geopolymer based ceramic with addition of Ultra High Molecular Weight Polyethylene as binder. Geopolymer were synthesized by fixing the NaOH molarity, Na₂SiO₃/NaOH and solid to liquid ratio at 12 M, 0.24 and 1.0 respectively. Geopolymer in a powder form with addition of various content of UHMWPE (2 wt.%, 4 wt.%, 6 wt.%, 8 wt.% ) were pressed into pellets followed by sintering at 1200 °C. The highest flexural strength of geopolymer based ceramics was achieved at sintering temperature of 1200 °C which is 92.1 MPa with a lowest density of 1.88 g/cm³.
