Epoxy Hardener Filled with Geopolymer Materials for Piping Application: Flexural Properties

Article Preview

Abstract:

In this study, the effect of geopolymer materials in epoxy hardener was studied under mechanical testing which is using flexural test. A series of epoxy filled with 10%-30% weight percentage geopolymer materials which are white clay, fly ash and silica sand was prepared. Flexural strength of the epoxy filled geopolymer materials is determined using Instron Universal Testing under flexural mode. It was found that the addition of these geopolymer materials into epoxy at the beginning with 10% weight percentage showing lower flexural strength than epoxy without geopolymer materials filled. However, flexural properties suddenly increased at 20% weight percentage of white clay and fly ash based geopolymer but tend to decrease at 30% weight percentage compared to silica sand based geopolymer which the strength is continue to decline with the increasing of weight percentage of silica sand. The results indicated that the blending of geopolymer materials in epoxy system can be obtained in this study.
