Collapsible loess aggregate filling material
The invention discloses a collapsible loess aggregate filling material, which is formed by jointly mixing aggregate, a curing agent, an additive and water, and the aggregate contains collapsible loess. The mixed filling material with the collapsible loess as the main body is provided by combining the raw materials such as the collapsible loess and the red sandstone which are common in northwest regions, and the mixed filling material is weak in shrinkage performance, low in consolidation settlement, free of collapsibility, low in permeability, capable of meeting the strength requirement and low in price in the backfilling process.
本发明公开了一种湿陷性黄土集料填筑材料，由集料、固化剂、外加剂、水共同混合组成，所述集料中包含湿陷性黄土。本发明结合西北地区较为常见的湿陷性黄土、红砂岩等原材料，提出了一种在回填过程中收缩性能弱、固结沉降低、无湿陷性、渗透性能低、强度满足要求且价格低廉的以湿陷性黄土为主体的混合填筑材料。
