Self-curing sludge-based material for road filler and preparation method of self-curing sludge-based material
The invention belongs to the technical field of building materials, and discloses a self-curing sludge-based material for road filler and a preparation method of the self-curing sludge-based material. The self-curing sludge-based material for the road filler comprises the following components in parts by weight: 70-90 parts of sludge, 10-30 parts of recycled aggregate, 5-15 parts of a curing agent, 1-5 parts of a heavy metal adsorption material, 5-10 parts of a self-curing material and 1-4 parts of a water reducing agent, the mass ratio of the blast furnace slag to the phosphogypsum to the cement is (1-3): (2-4): (1-3). The self-curing sludge-based material for the road filler provided by the invention turns waste into wealth, has the advantages of low cost, heavy metal ion adsorption, self-curing, environmental friendliness and the like, and can greatly relieve the problem that municipal sludge and construction waste are difficult to treat at present.
本发明属于建筑材料技术领域,公开了一种用于道路填料的自养护污泥基材料及其制备方法。本发明用于道路填料的自养护污泥基材料按重量份数计,包含污泥70‑90份,再生骨料10‑30份,固化剂5‑15份,重金属吸附材料1‑5份,自养护材料5‑10份,减水剂1‑4份,其中,所述固化剂由高炉矿渣、磷石膏和水泥三元胶凝体系组成,且高炉矿渣、磷石膏和水泥的质量比为1‑3:2‑4:1‑3。本发明用于道路填料的自养护污泥基材料变废为宝,具有成本低廉、吸附重金属离子、自养护、环境友好等优势,可大幅度缓解目前市政污泥和建筑垃圾处理难的问题。
