Active magnesium-rich stone powder and solid waste composite geopolymer material and preparation method thereof
The invention relates to an active magnesium-rich stone powder and solid waste composite geopolymer material, which comprises a solid component, a liquid component and an alkali activator, the weight ratio of the solid component to the liquid component is 175.2: 30.9, the alkali activator accounts for 1-3% of the total weight of the solid component and the liquid component, and the solid component, the liquid component and the alkali activator account for 1-3% of the total weight of the solid component and the liquid component. The additive comprises the following components in percentage by weight: 40-90% of active magnesium-rich stone powder and 10-60% of fly ash or mineral powder, the liquid component comprises the following components in percentage by weight: 66.6% of sodium silicate and 33.4% of water; the active magnesium-rich stone powder is stone powder with the MgO content larger than 15% through XRF measurement and conversion, and the stone powder is treated at the temperature of 800-1000 DEG C for 4-10 hours. The activated magnesium-rich stone powder and various solid wastes are compounded for use, so that the emission of industrial wastes can be reduced, the recycling of the wastes is realized, the production cost of a new material is reduced, and the economic benefit is improved.
本发明涉及一种活性富镁石粉与固废复合地聚物材料，包括固体成分、液体成分和碱激发剂，所述的固体成分：液体成分的重量比为175.2:30.9，所述的碱激发剂为固体成分和液体成分总重的1‑3％，所述的固体成分，按照重量百分比计包括：活性富镁石粉40％‑90％、粉煤灰或矿粉10％～60％；所述的液体成分，按照重量百分比计包括：硅酸钠66.6％和33.4％水；所述的活性富镁石粉为采用XRF测定折算MgO含量大于15％石粉，经800～1000℃处理4～10小时。本发明通过活化富镁石粉与多种固体废物的复合使用，可以减少工业废物的排放，实现废物的资源化，降低新材料的生产成本，提高经济效益。
