Feasibility Study of Metakaolin-Based Geopolymer as Binder for Construction Mortar
Publication: Tran-SET 2020
ABSTRACT
Geopolymer is an aluminosilicate network polymer that has gained interest in recent years as an eco-friendly alterative to ordinary Portland cement for transportation infrastructure. This novel material can be processed from waste and/or widely available natural materials under ambient conditions. In this study, a comprehensive set of metakaolin-based geopolymers and geopolymer mortars with construction sand were processed using different SiO2/Al2O3 ratios and water/solid ratios for geopolymer binder and cured at ambient conditions for 14 days. Pure geopolymer and geopolymer mortar samples were tested for compressive strength, density, and open porosity. The results show that the composition of geopolymers strongly affects their properties especially their compressive strength. Samples with various compositions were characterized with scanning electron microscopy (SEM) to examine the morphological and structural effect from the compositional parameters.
