Lightweight quick setting top-caving area filling material
The invention discloses a lightweight quick setting top-caving area filling material. The lightweight quick setting top-caving area filling material is mixed by primary materials B and primary materials B, wherein the primary materials consist of sulfate aluminum cement, coal ash, a water reducer, a setting accelerator, a foaming agent and a dispersing agent; the primary materials B consist of gypsum, lime, a water reducer, a setting accelerator, a dispersing agent and a foaming agent. The lightweight quick setting top-caving area filling material has the lightweight quick setting characteristic; after entering and filling into a top-caving area, the foamed slurry can quickly lose mobility and is solidified within 5 minutes to form a lightweight filling body, wherein the density of the filling body is about 1.4t/m<3>, the 2h uniaxial compressive strength can reach 4 MPa, certain compression performances are provided, the performances of the filling body are stable, the cracking deformation is avoided, and the filling needs of the top-caving area can be met very well.
