Flow state filling material for culvert abutment back backfilling and preparation method thereof
The invention relates to a flow-state filling material for culvert abutment back backfilling. The flow-state filling material is prepared from the following components in parts by mass: 1 part of engineering residue soil on the basis of dry weight, 0.25-0.33 part of a curing agent, 0.4 part of fine sand and 0.00375-0.00495 part of a water reducing agent, the curing agent comprises slaked lime and metakaolin, and the mass ratio of the slaked lime to the metakaolin is 2: 3-3: 2. The invention further relates to a preparation method of the flow-state filling material for culvert abutment back backfilling. The flow value of the flow-state filling material is larger than 140 mm, self-sealing and vibration-free effects can be achieved, the efficiency of culvert backfilling construction operation is remarkably improved, and the flow-state filling material belongs to the technical field of building materials.
本发明涉及一种涵洞台背回填的流态填充材料，包含以下质量份的各组分：工程渣土以干重计1份、固化剂0.25～0.33份、细砂0.4份、减水剂0.00375～0.00495份；固化剂包含熟石灰和偏高岭土，熟石灰和偏高岭土的质量比为2:3～3:2。本发明还涉及一种涵洞台背回填的流态填充材料的制备方法。本发明的流态填充材料的流动值大于140mm，可以实现自密性、免振捣，显著提高涵洞回填施工作业的效率，属于建筑材料技术领域。
