Alkali-activated cementing material as well as preparation method and application thereof
The invention provides a gel alkali-activated cementing material as well as a preparation method and application thereof, and belongs to the technical field of building materials. The cementing material comprises a composite precursor material and an alkali activator, and the composite precursor material is formed by compounding coal gangue and waste incineration fly ash or bottom slag; the alkali activator comprises one or two of a NaOH solution and a Na2SiO3 solution. Most of the adopted materials are solid waste materials, the production process is simple, calcination is not needed, the cost is low, the CO2 emission amount is small, the mechanical property of the obtained high-strength environment-friendly alkali-activated cementing material is excellent, heavy metal in waste can be effectively solidified, and the high-strength environment-friendly alkali-activated cementing material is environmentally friendly and has wide market popularization prospects.
本发明提供一种胶碱激发胶凝材料及其制备方法和应用,属于建筑材料技术领域。所述胶凝材料包括复合前驱体材料和碱激发剂,其中,所述复合前驱体材料由煤矸石和垃圾焚烧飞灰或底渣复合而成;所述碱激发剂包括NaOH和Na2SiO3溶液中的一种或两种。本发明所采用的材料大部分为固体废弃物材料,其生产工艺简单,无需煅烧,成本较低,CO2排放量小,所得高强环保碱激发胶凝材料力学性能较为优异,且能够有效固化废物中的重金属,对环境友好,具有广阔的市场推广前景。
