Properties of Geopolymer Mortar Subjected to High Temperature
Geopolymer concrete was presented to produce alternative binder to cement. This study considered the influence of silica fume on the properties of metakaolin based geopolymer mortar exposed to high temperature up to 800 °C. Five mortar mixes were used with silica fume replacing level of 0, 10, 20, 30 and 40% of weight of metakaolin. The results demonstrated that the compressive and splitting tensile strength increased with increasing the silica fume replacing level up to 40% of weight of metakaolin for all burning temperature and the absorption was decreased with it. The outcomes also demonstrated that for the same mix the compressive and splitting tensile strength improved with increment burning temperature up to 400 °C and reduced with increasing the temperature above it until 800 °C.
