Geopolymer was prepared by mixing fly ash and alkali activator. The silica fume was added in 2% and 4% by weight. The geopolymer samples were cured at room temperature for 28 days before exposed to an elevated temperature up to 1000 °C. The incorporation of 2% silica fume did not cause significant improvement in the compressive strength of unexposed geopolymer. Higher silica fume content of 4% reduced the compressive strength of the unexposed geopolymer. When subjected to elevated temperature, geopolymer with 2% silica fume retained higher compressive strength at 1000 °C. The addition of silica fume in fly ash geopolymer caused a lower degree of shrinkage and expansion, as compared to geopolymer without the addition of silica fume. Crystalline phases of albite and magnetite were formed in the geopolymer at 1000 °C 2022 2022-03-23T01:00:53Z 2022-03-23T01:00:53Z 2021-01 Article Magnetochemistry, vol.7(1), 2021, 14 pages 2312-7481 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/74751 https://doi.org/10.3390/magnetochemistry7010009 en MDPI AG |
