More Information
Summary:The invention belongs to the technical field of low-carbon cementing materials, and particularly relates to a modified low-shrinkage low-carbon cementing material prepared from red mud and a preparation method of the modified low-shrinkage low-carbon cementing material. The low-carbon cementing material is prepared from the following raw materials in parts by weight: 170 to 260 parts of fly ash, 170 to 260 parts of mineral powder, 90 to 130 parts of liquid sodium silicate, 13 to 20 parts of sodium hydroxide, 110 to 180 parts of water, 1000 to 1400 parts of sand, 8 to 13 parts of molybdenum disulfide, 35 to 50 parts of ammonia water, 10 to 15 parts of diluted hydrochloric acid and 80 to 150 parts of red mud. Molybdenum disulfide and red mud are added into diluted hydrochloric acid to be mixed, then the low-carbon cementing material is prepared, the strength and shrinkage rate of the low-carbon cementing material are improved, the utilization rate of molybdenum disulfide is increased, and red mud recycling is a
