| titleOfInvention | Environment-friendly portland cement and preparation method thereof |
| abstract | The invention relates to an environment-friendly portland cement and a preparation method thereof, belonging to the technical field of cement, wherein the raw materials of the environment-friendly portland cement comprise portland cement clinker, microbial sludge, phosphogypsum, fly ash, slag, limestone, dihydrate gypsum, silicon dioxide and additives, and the additives comprise maleic anhydride modified triethanolamine, maleic anhydride, acetic acid, trimellitic anhydride glyceride, isopentenol polyoxyethylene ether, sodium fatty acid, dodecylamine polyoxyethylene ether, calcium lignosulfonate and molasses. The environment-friendly portland cement has high flexural strength and compressive strength, the application range is enlarged, the production cost is reduced, the additive has a good reinforcing effect on the portland cement, the adverse effect of the additive on the compatibility of the cement and a water reducing agent is reduced, meanwhile, the recycling of wastes is realized by adding the microbial sludge and the phosphogypsum, and the production cost of the environment-friendly portland cement is reduced. |
