| Özet |
| This study investigated the mechanical, physical, and microstructural properties of the composites produced from waste geopolymer powder like semi-lightweight concrete. Hydraulic lime (150 kg/m3) was used as CaO source in geopolymer mixtures. Quartz powder was also used as filler to reduce porosity in the mixtures. While the binder ratio in the mixtures varies between 800 and 1200 kg/m3, the Na2SiO3/NaOH ratio is 2.5. The hardened unit weight of the mixtures varies between 1878 and 2041 kg/m3. After heat curing for 12 h at 60 and 80 °C, compressive strength of 9.7–26.6 MPa was obtained. Their compressive strength generally decreased, if the mixtures were left in the air for 28 days after heat curing. However, the compressive strength of the samples subjected to water curing for 28 days varies between 10.7 and 35.5 MPa. When the curing temperature increased, the capillary water absorption of the … |
