| titleOfInvention | Cement grinding aid and preparation method thereof |
| abstract | The invention provides a cement grinding aid and a preparation method thereof, belonging to the technical field of cement manufacture and prepared from the following raw materials in parts by weight: 70-120 parts of composite fermentation product, 5-12 parts of talcum powder, 10-30 parts of organic amine, 12-20 parts of surfactant, 2-5 parts of calcium lignosulphonate and 200 parts of water; the composite fermentation product is a fermentation product of a mixed substrate of beet molasses, linseed and lignin. The cement grinding aid provided by the invention has the advantages of easily available raw materials, low price, simple and feasible preparation method, mild reaction conditions, low requirements on reaction equipment and suitability for industrial production. The paint does not contain any chloride ion component, is nontoxic, green and environment-friendly, has no corrosiveness, and does not damage human bodies, buildings and the like; the cement grinding aid meets the standard requirements of the grinding aid, has excellent grinding aid effect, can improve compressive strength, and is low in doping amount which is only 0.03-0.04% of the cement dosage. |
