Kaolin-Based Geopolymer Filled Epoxy-Layered Silicates: Compressive Properties

Abstract:

The present work aimed to study the effects of kaolin-based geopolymers in epoxy-layered silicate nanocomposites using a compressive test. A series of nanocomposites with kaolin-based geopolymers containing 1-7 phr content were prepared. A qualitative evaluation of the three-dimensional shape of a kaolin-based geopolymer surface and origin was characterised using the scanning electron microscopy (SEM). It was discovered that the addition of kaolin based geopolymer at the beginning, in low phr content, displayed a lower compressive strength than nanocomposites without kaolin based geopolymer filled. However, the compressive properties unexpectedly increased at 3phr of kaolin geopolymer content compared to nanocomposites without kaolin. This illustrated that the incorporation of kaolin geopolymers in the nanocomposite system can potentially improved the mechanical properties of the epoxy resin, thereby needs further exploration.
