The invention relates to the technical field of building material preparation, in particular to alkali-activated fully-recycled aggregate concrete and a preparation method thereof. The alkali-activated fully-recycled aggregate concrete disclosed by the invention is prepared from the following components in parts by weight: 350 to 650 parts of solid raw materials, 150 to 400 parts of alkaline raw materials, 600 to 1200 parts of recycled coarse aggregates, 200 to 800 parts of recycled fine aggregates, 20 to 100 parts of water and 0.9 to 20 parts of fibers. According to the prepared recycled concrete, industrial solid waste such as mineral powder and fly ash and building solid waste are fully utilized, cement is not needed, and consumption of natural gravel and river sand is reduced; the production process is low in cost, green, low in carbon, energy-saving and emission-reducing, and resource utilization of solid waste is effectively realized; the alkali-activated fully-recycled aggregate concrete is high in strength and good in toughness; the preparation method is simple in process and convenient to operate, overcomes adverse effects of strength and volume stability brought by recycled coarse and fine aggregates, meets actual engineering requirements, and has remarkable economic, social and environmental benefits.
本发明涉及建筑材料制备技术领域，尤其是涉及一种碱激发全再生骨料混凝土及其制备方法。本发明的碱激发全再生骨料混凝土包括以下重量份的各组分：固体原料350～650份、碱性原料150～400份、再生粗骨料600～1200份、再生细骨料200～800份、水20～100份、纤维0.9～20份。本发明制备的再生混凝土充分利用了矿粉、粉煤灰等工业固废和建筑固废，无需水泥，并减少了天然碎石和河砂的消耗；生产过程成本低廉、绿色低碳、节能减排，有效地实现了固废的资源化利用；碱激发全再生骨料混凝土强度高、韧性好；制备方法工艺简单、操作方便，且克服了再生粗、细骨料带来的强度和体积稳定性的不利影响，满足实际工程要求，经济、社会和环境效益显著。
