Double-expansion filling mortar
The invention provides double-expansion filling mortar. The double-expansion filling mortar per cubic meter comprises, by mass, the following ingredients of 100-120 kg of cement, 340-360 kg of fly-ash, 950-970 kg of sand, 1.84-2.76 kg of a water reducing agent, 50 kg of an expanding material, 0-13.8 kg of silica fume and 310-330 kg of water, wherein the water reducing agent is a polycarboxylate superplasticizer powder agent. The double-expansion filling mortar can be used for the fields including tunneling shields, coal mine backfilling, urban duct backfilling and the like, compared with traditional filling mortar, the mobility and the degree of density of the filling mortar are improved, the delayed coagulation is achieved, in addition, the transformation performance of the filling mortar is improved, and the economic benefit of the filling mortar is improved.
