Abstract

Solid activators based on waste glass for the manufacture of one-part alkali-activated fly ash/red mud materials were synthesized, characterized, and tested in this work. The synthesis was carried out via alkaline fusion with sodium hydroxide at different reaction temperatures and at different sodium hydroxide/waste glass mass ratios. The results showed that the reaction temperature decisively influences the properties of the obtained solid activators. Thus, the best results regarding the water solubility of solid activators were obtained for the synthesis temperature of 600 °C, regardless of the sodium hydroxide/waste glass mass ratio. Also, the use of these assortments of solid activators led to obtaining the best compressive strength of one-part alkali-activated fly ash/red mud materials. The best results were obtained for the solid activator synthesized at a temperature of 600 °C and a sodium hydroxide/glass waste mass ratio of two.

摘要

在本研究中，合成了基于废玻璃的用于制造单组分碱激发粉煤灰/赤泥材料的固体激发剂，对其进行了表征和测试。通过在不同反应温度和不同氢氧化钠/废玻璃质量比下与氢氧化钠进行碱熔来进行合成。结果表明，反应温度对所得固体激发剂的性能具有决定性影响。因此，无论氢氧化钠/废玻璃质量比如何，在600℃的合成温度下获得的固体激发剂的水溶性最佳。此外，使用这些种类的固体激发剂能够使单组分碱激发粉煤灰/赤泥材料获得最佳抗压强度。在600℃的温度和氢氧化钠/玻璃废料质量比为2的条件下合成的固体激发剂取得了最佳结果。
