Özet
In this study, metakaolin based geopolymer mixtures using granulated blast furnace slag and different sizes of quartz aggregate were thermally cured at 30–60–90°C for 4, 6, and 8 h. Sodium hydroxide and sodium silicate were used as alkali activators in the experiments. Early (1 d), and 28-days mechanical strengths, transport (capillarity) properties, unit weights at hardened stage, microstructural features of the mixes obtained at different curing time and curing temperature were observed. The compressive strength of the geopolymer mixtures was measured between 41.7–106.5 MPa, at early ages; and the 28 days compressive strength between 23.6–80.5 MPa. The flexural strengths varied between 7.2–22.9 MPa for 1 d. Increased the curing temperature and curing time tended to surge the mechanical properties of the mixtures while increasing aggregate size tended to decrease these properties. The unit …
