| titleOfInvention | A kind of dry-mix shotcrete material composition for underground roadway of coal mine and preparation method thereof |
| abstract | The invention discloses a dry-mixed shotcrete material composition for underground tunnels in coal mines, which comprises the following raw materials: 30-60 parts by weight of natural sand, 5-30 parts by weight of machine-made sand, and 20-30 parts by weight of fly ash parts, 0.6-1.0% by volume of short fiber material, 150-300 parts by weight of cement, 1-2 parts by weight of defoamer, 3-8 parts by weight of water reducing agent, 5-15 parts by weight of accelerator ; Wherein, the machine-made sand is made by smashing construction waste and then being coated. In the present invention, the machine-made sand is dipped in sodium silicate solution, pretreated with aminosilane coupling agent and coated with cellulose, so that construction waste can be efficiently used in dry-mixed shotcrete materials, and the amount of construction waste is reduced. produced, reducing environmental pollution. |
