Pipe jacking sludge stabilizer, roadbed material and preparation method of roadbed material
The invention discloses a pipe jacking sludge stabilizer, a roadbed material using the stabilizer and a preparation method of the roadbed material, and relates to the field of pipe jacking sludge utilization. 10 to 20 parts of phosphogypsum; 15-30 parts of an alkali activator; 2-4 parts of an activator; the activating agent comprises one or two of triethanolamine and sodium lignin sulfonate. The method has the advantages that resource utilization is carried out in the mode that the pipe jacking sludge is used for manufacturing the roadbed material, and the unconfined compressive strength of the roadbed material with the pipe jacking sludge as the base body is improved.
本申请公开了一种顶管淤泥稳定剂、使用该稳定剂的路基材料及其制备方法，涉及顶管淤泥利用领域，其包括以下重量份的组分：高炉矿渣50‑62份；磷石膏10‑20份；碱激发剂15‑30份；活化剂2‑4份；所述活化剂包括三乙醇胺和木质素磺酸钠中的一种或两者。本申请具有利用顶管淤泥通过制作路基材料的方式进行资源化利用，并且提高了以顶管淤泥为基体的路基材料的无侧限抗压强度的效果。
