Method for improving long-term fly ash solidification effect of fly ash cement solidification body
The invention discloses a method for improving the long-term fly ash solidification effect of a fly ash cement solidification body, and belongs to the technical field of fly ash solidification, the method comprises the following steps: S1, collecting household garbage incineration fly ash, and carrying out hydrothermal treatment on the household garbage incineration fly ash to form uniform slurry; s2, the viscosity of the slurry is adjusted, synthetic fibers or metal fibers are gradually added into the slurry with the adjusted viscosity, and slurry containing the synthetic fibers or the metal fibers is obtained; s3, after pouring condensation is conducted, a cement solidification body is obtained, and a jaw crusher is used for crushing the cement solidification body; and respectively heating the polymer modified asphalt and the matrix asphalt to 160-185 DEG C, and keeping the temperature in the range to obtain the cement solidified body coated with the asphalt. The anti-carbonation performance of the fly ash cement solidified body can be improved, aging of the fly ash cement solidified body is prevented, the long-term stability of the fly ash cement solidified body is improved, and the long-term fly ash solidification effect of the fly ash cement solidified body is improved.
本发明公开了一种提高飞灰水泥固化体长期固化飞灰效果的方法，属于飞灰固化技术领域，该方法包括以下步骤：S1、收集生活垃圾焚烧飞灰，将生活垃圾焚烧飞灰先进行水热处理，形成均匀的浆料；S2、调整浆料的粘度，往调整粘度的浆料中逐渐加入合成纤维或金属纤维，得到包含合成纤维或金属纤维的浆料；S3、进行浇筑凝结后，得到水泥固化体，使用颚式破碎机粉碎水泥固化体；将聚合物改性沥青和基质沥青分别加热到160℃‑185℃，保持在该温度范围，得到沥青包覆的水泥固化体。本发明能够提高飞灰水泥固化体的抗碳酸化性能，防止飞灰水泥固化体的老化，提高飞灰水泥固化体的长期稳定性，提高飞灰水泥固化体长期固化飞灰效果。
