The invention relates to the technical field of building materials, and particularly relates to a gypsum ground expansion backfill material. Aiming at the problems that in the prior art, a ground pitbackfill material is low in compressive strength and prone to deformation, a technical scheme is provided, wherein raw materials comprise, by weight, 2-5 parts of amino protein powder, 2-5 parts of nano linear alkyl, 1-2.5 parts of a nano hyperdispersant, 8-20 parts of bone collagen powder, 4-10 parts of leveling powder, 5-12.5 parts of defoaming powder, 16-40 parts of a thixotropic lubricant, 40-100 parts of quartz sand, 20-50 parts of gypsum powder and 25-62.5 parts of nano calcium carbonate. The compressive strength of the bottom surface pit backfill material is effectively improved, the raw materials do not pollute the environment, after backfilling, the backfill material can densely fill underground gaps, and the problem that the backfill material sinks is avoided.
本发明涉及建筑材料技术领域，尤其是一种石膏地面膨胀回填宝，针对现有技术中的地面坑洞回填材料抗压强度低和容易变形的问题，现提出如下方案，其原料按重量份包括：氨基蛋白粉2‑5份，纳米直链烷基2‑5份，纳米超分散剂1‑2.5份，骨胶原粉8‑20份，流平粉4‑10份、消泡粉5‑12.5份、触变润滑剂16‑40份，石英砂40‑100份、石膏粉20‑50份，纳米碳酸钙25‑62.5份。本发明有效提高了底面坑洞回填物的抗压强度，而且原材料不污染环境，回填后，回填材料可密集填充地下空隙，避免了回填料沉陷的问题。
