Roadbed stabilizing material prepared from sulfur-containing tailings
The invention discloses a roadbed stabilizing material prepared from sulfur-containing tailings, which comprises the following main raw materials: sulfur-containing tailings, lime and fly ash, and is characterized by comprising the following components in parts by weight: 1-15 parts of lime, 3-15 parts of fly ash, 3-15 parts of slag, 0-6 parts of slag ash, 3-30 parts of urban common tap water and 40-90 parts of sulfur-containing tailings. The cement system composed of lime, fly ash, slag and the like is adopted to cement the sulfur-containing tailings to prepare the roadbed stabilizing material, the cement problem of the sulfur-containing tailings is effectively solved, sulfate formed by oxidation of the sulfur-containing tailings can be utilized to promote decomposition of the fly ash, the slag and the like, more hydration products are formed, harm is turned into treasure, and the roadbed stabilizing material is environmentally friendly. The method has outstanding economic, social and environment-friendly benefits, and has a huge application prospect.
本发明公开了一种利用含硫尾砂制备的路基稳定材料，包括如下主要原料：含硫尾砂、石灰、粉煤灰，其特征是重量份组成为：石灰1～15份，粉煤灰3～15份，矿渣3～15份，炉渣灰0～6份，城市普通自来水3～30份，含硫尾砂40～90份。本发明采用石灰、粉煤灰、矿渣等组成的胶结体系胶结含硫尾砂，制成路基稳定材料，不仅有效解决了含硫尾砂的胶结难题，而且可利用含硫尾砂氧化形成的硫酸盐促使粉煤灰、矿渣等分解，形成更多水化产物，实现变害为宝，具有突出的经济、社会、环保效益，应用前景巨大。
