All-solid-waste roadbed cushion material and preparation method thereof
The invention provides an all-solid-waste roadbed cushion material and a preparation method thereof.The preparation method comprises the steps that coal-fired furnace slag is crushed and screened and then divided into first furnace slag, second furnace slag and third furnace slag according to different particle size ranges, then weighed ardealite, steel slag powder and lead-zinc tailing powder are mixed according to preset weight parts and then subjected to wet grinding, and mixed slurry is obtained; and weighing the required quick lime, the first slag, the second slag and the third slag according to preset parts by weight, pre-stirring, adding a water reducing agent, the mixed slurry and water, and fully stirring to obtain the all-solid-waste roadbed cushion material. Through the mode, the synergistic effect of the raw materials can be effectively utilized, and heavy metal ions are effectively cured while formation of hydration products is promoted, so that solid waste materials which are low in price and difficult to treat are prepared into the all-solid-waste roadbed cushion material which is good in mechanical property and high in stability, and the all-solid-waste roadbed cushion material has relatively high economic benefits and environmental benefits.
本发明提供了一种全固废路基垫层材料及其制备方法，通过将燃煤炉渣破碎筛分后按照不同的粒径范围划分为第一炉渣、第二炉渣和第三炉渣，再按照预设的重量份数将称取的磷石膏、钢渣粉和铅锌尾矿粉混合后进行湿磨，得到混合浆体；然后按照预设的重量份数称取所需的生石灰、第一炉渣、第二炉渣和第三炉渣，预搅拌后再加入减水剂、混合浆体和水进行充分搅拌，得到全固废路基垫层材料。通过上述方式，本发明能够有效利用各原料之间的协同作用，在促进水化产物形成的同时对重金属离子进行有效固化，从而将廉价且难处理的固废材料制备成力学性能好、稳定性高的全固废路基垫层材料，具有较高的经济效益和环境效益。
