Moderately weathered argillaceous siltstone improved filler and preparation method thereof
The improved filler for the intermediary weathered argillaceous siltstone is characterized by being prepared from the following materials: intermediary weathered argillaceous siltstone fine aggregate,intermediary weathered argillaceous siltstone coarse aggregate, gravels, cement, quick lime and water. The mass part ratio of all the materials is 180:(240-260):(180-220):(50-100):(60-100):(110-150).The invention further provides a preparation method of the intermediary weathered argillaceous siltstone improved filler. The method can effectively overcome the defects of the conventional method for obtaining the backfill. The filler not only can improve the intermediary weathered argillaceous siltstone, but also is simple and feasible, convenient to operate and low in manufacturing cost.
中风化泥质粉砂岩改良填料，其特征在于，由以下材料制备而成：中风化泥质粉砂岩细骨料、中风化泥质粉砂岩粗骨料、碎石、水泥、生石灰和水，各个材料的质量份数比为：180：(240‑260)：(180‑220)：(50‑100)：(60‑100)：(110‑150)。以及提供一种中风化泥质粉砂岩改良填料的制备方法。本发明能有效地克服上述常规获取回填料方法的缺点。本发明不但可以实现对中风化泥质粉砂岩进行改良，而且简单易行、操作方便、造价低。
