| titleOfInvention | Red mud-based cementing material excitant and red mud-based goaf filling material |
| abstract | The invention discloses a red mud-based cementing material excitant and a red mud-based goaf filling material. The red mud-based cementing material excitant comprises the following components: desulfurized gypsum, fly ash, soda ash, mirabilite, sodium silicate, sodium dihydrogen phosphate and bauxite. The red mud-based goaf filling material comprises a red mud-based cementing material excitant, red mud, steel slag, cement, basalt fiber chopped yarn and sericite reinforced polypropylene master batch. The composite excitant can effectively excite the red mud to form the filling material with stable structure and performance, and the filling material has good fluidity and compressive strength and can meet the requirement of filling the mine goaf. Compared with the traditional cementing material mainly containing cement, the red mud-based goaf filling material provided by the invention also has expansibility, can inhibit volume shrinkage in the cement hardening process, and can solve the problem of void existing in the conventional filling area. |
