Özet
Geopolymer slurries can be favored to achieve a sustainable approach in prepacked aggregate concretes. This study presented here investigated experimentally the effect of silica fume (SF) and rice husk ash (RHA) on the high-temperature resistance of slag-based sustainable prepacked geopolymers. In the production of prepacked aggregate geopolymers (PAGs), ground granulated blast furnace slag (GGBFS) was utilized as the main aluminosilicate-rich precursor material, and SF and RHA were replaced with GGBFS in various contents including 7.5 % and 15 %. The physical, mechanical, and microstructural properties of specimens cured at 35 °C and 70 °C for 8 h were determined comparatively. Residual compressive strength and mass loss of mixtures exposed to elevated temperatures (150 °C, 300 °C, and 600 °C) were determined to observe high-temperature effects. The results revealed that the properties …
