Muck artificial aggregate based on alkali excitation and cold bonding granulation technology and preparation method thereof
The invention provides a muck artificial aggregate based on an alkali excitation and cold bonding granulation technology. The muck artificial aggregate is prepared from powder and a solution, the powder comprises blast furnace slag powder and engineering muck; the solution is prepared by compounding a water glass solution, solid sodium hydroxide and water. The invention also provides a preparation method of the artificial aggregate, the main raw materials of the artificial aggregate prepared by the invention are industrial wastes (engineering residue soil) and industrial byproducts (granulated blast furnace slag powder), the proportions of the wastes and the industrial byproducts are more than 80%, high-carbon-emission cementing materials such as Portland cement are not needed, and the cost is low. The prepared aggregate has good environmental benefits, and is high in crushing strength and relatively uniform in particle size distribution. In addition, the alkali-activated granulated blast-furnace slag powder used in the invention can be naturally hardened at normal temperature, meets the development requirements of green building materials, and has high commercial value and popularization value.
本发明提供了一种基于碱激发与冷粘造粒技术的渣土人造骨料，所述渣土人造骨料由粉料以及溶液组成；所述粉料包括高炉矿渣粉以及工程渣土；所述溶液由水玻璃溶液、固体氢氧化钠以及水复配而得。本发明还提供了上述人造骨料的制备方法，本发明制备得到的人造骨料主要原料均为工业废弃物(工程渣土)和工业副产物(粒化高炉矿渣粉)，废弃物及工业副产物占比在80％以上，无需使用硅酸盐水泥等高碳排胶凝材料，制备骨料具有良好的环境效益，且压碎强度高，粒径分布较为均匀。此外，本发明使用的碱激发粒化高炉矿渣粉在常温条件下可自然硬化，符合绿色建材的发展需求，具备较高的商业价值与推广价值。
