Solid waste-based unfired artificial aggregate and preparation method thereof
The invention relates to the technical field of building materials, in particular to a solid-waste-based unfired artificial aggregate and a preparation method thereof. The solid waste-based unfired artificial aggregate is prepared from the following components in parts by mass: 852 to 1353 parts of fly ash, 490 to 927 parts of slag, 143 to 223 parts of an alkali activator and 189 to 283 parts of water, the artificial aggregate prepared by the invention has the advantages of high compressive strength, low bulk density, light weight, high strength and low water absorption rate, completely meets various performance requirements of high-strength aggregate, can replace natural aggregate (mainly including sand and stone) to be used as a raw material of concrete, greatly reduces the use and exploitation of natural gravel aggregate, and has the advantages of low cost and high economic benefit. The mine can be effectively protected, natural resources are saved, a sustainable development production method is provided for the concrete construction industry, and the method has important significance.
本发明涉及建筑材料技术领域，具体涉及一种固废基免烧人造骨料及制备方法；本发明一种固废基免烧人造骨料，按照质量份数计包括：粉煤灰852份～1353份、矿渣490份～927份、碱激发剂143份～223份和水189份～283份；本发明制备的人造骨料压强度较高，堆积密度低，具有轻质高强，吸水率低的优点，完全符合高强度骨料的各种性能要求，能够替代天然骨料(主要包括一些砂、石)作为混凝土的原料使用，大大减少了天然砂石骨料的使用和开采，能够有效的保护矿山、节约自然资源，为混凝土建筑行业提供了一种可持续发展的生产方法，具有重要的意义。
