Beschreibung
Zusammenfassung:	A foamed cement-soil slurry for backfilling building fertilizer tanks comprises the following components in parts by weight: 20-80 parts of clay or silt, 20-80 parts of brick slag or concrete slag, 30-70 parts of sandy soil, 10-20 parts of cement, 0.05-0.2 part of powdery foaming agent, 50-90 parts of water and 0-0.2 parts of additive (i.e. foam stabilizer); according to the parts by weight, all the above ingredients are put into a blender and stirred evenly to obtain a mixture, then the baffle of the discharge port is opened, and the mixture is conveyed and poured into the building fertilizer tanks to be backfilled by a delivery pump. The invention can achieve the effect of volume increase by adding a proper foaming agent, and has good workability, and can meet the needs of filling fertilizer tanks regardless of strength, permeability, subsidence prevention and other properties.
