| description | The invention relates to the technical field of mine filling, and particularly discloses a gangue paste cementing material and a preparation method thereof, and a gangue paste filling material and a preparation method thereof. The gangue paste cementing material is prepared from the following components in parts by mass: 20 to 30 parts of Portland cement clinker, 2 to 4 parts of sulphoaluminate cement clinker, 5 to 10 parts of modified gypsum, 60 to 70 parts of mineral powder, 5 to 10 parts of limestone powder, 0.2 to 0.3 part of sodium silicate and 2 to 4 parts of additive. The gangue paste filling material is prepared from the following components in percentage by mass: 2.5 to 3 percent of gangue paste cementing material, 16 to 18.5 percent of gangue, 5 to 6 percent of fly ash and the balance of water. The gangue paste cementing material can replace cement to serve as a cementing material to play a role in a gangue paste filling material, the manufacturing cost of the gangue paste filling material is reduce |
