Overwet soil modifying material as well as preparation method and application method thereof

The invention relates to the technical field of road engineering materials, and particularly discloses an over-wet soil modified material as well as a preparation method and an application method thereof. The over-wet soil modified material is prepared from the following raw materials in parts by mass: 80 to 140 parts of silicon iron waste residue, 50 to 100 parts of phosphogypsum, 60 to 100 parts of carbide slag, 8 to 17 parts of straw fiber and 10 to 25 parts of calcium chloride. The overwet soil modified material obtained by the invention can effectively and quickly reduce the moisture content of overwet soil, is relatively low in cost, and has relatively high practical application value. 本申请涉及道路工程材料技术领域，具体公开了一种过湿土改性材料及其制备方法、应用方法。一种过湿土改性材料，包括以下质量份的原料：硅铁废渣80-140份、磷石膏50-100份、电石渣60-100份、秸秆纤维8-17份、氯化钙10-25份。本申请得到的过湿土改性材料能够有效且快速地降低过湿土的含水率，且成本较低，具有较强的实际应用价值。
