Abstract

Geopolymer materials are increasingly being considered as an alternative to environmentally damaging concrete based on Portland cement. The presented work analyzed waste from mines and waste incineration plants as potential precursors for producing geopolymer materials that could be used to make lightweight foamed geopolymers for insulation applications. The chemical and phase composition, radioactivity properties, and leachability of selected precursors were analyzed. Then, geopolymer materials were produced, and their strength properties were examined through compression and flexural tests. The results of the strength tests guided the material selection for foamed geopolymer materials. Next, geopolymer foams were foamed with hydrogen peroxide and aluminum powder. The produced foamed materials were subjected to strength and thermal conductivity tests. The results demonstrated the great potential of mine waste in the synthesis of geopolymers and the production of lightweight geopolymer foams with good insulating properties.

摘要

地质聚合物材料越来越被视为一种替代对环境有害的基于波特兰水泥的混凝土的材料。所展示的工作分析了矿山废料和垃圾焚烧厂的废料,将其作为生产地质聚合物材料的潜在前驱体,这些材料可用于制造用于保温应用的轻质泡沫地质聚合物。分析了所选前驱体的化学和相组成、放射性特性及浸出性。然后,制备了地质聚合物材料,并通过压缩和弯曲试验检测其强度性能。强度试验结果为泡沫地质聚合物材料的选材提供了指导。接下来,用过氧化氢和铝粉对地质聚合物进行发泡。对所制备的泡沫材料进行强度和热导率测试。结果表明,矿山废料在地质聚合物合成以及生产具有良好保温性能的轻质地质聚合物泡沫方面具有巨大潜力。
