Mineralized material used in cement grinding process
The invention is suitable for the technical field of cement grinding aids, and provides a mineralized material used in a cement grinding process, the mineralized material is composed of the following substances by mass: 2-5% of sodium sulfate, 4-7% of sodium thiosulfate, 0-3% of sodium sulfite, 1-3% of maleic anhydride dimer acid triethanolamine ester, 1-3% of ethylene glycol, and 79-92% of fly ash. By determining proper substances and content, promoting early hydration of cement and greatly improving the early hydration rate of cement particles, the early strength is improved, the hydration durability is considered, the later hydration of the cement is promoted through sodium thiosulfate, maleic anhydride dimer acid triethanolamine ester and ethylene glycol, the strength of cement paste is improved, and the cement paste can also wrap the surface of cement particles to form a protective film to eliminate bonding and adsorption agglomeration, the maleic anhydride dimer acid triethanolamine ester can form an oxidation protection film on the metal surface to retard the corrosion of steel bars so that the machine-hour yield of a mill is increased, the comprehensive performance of the product is improved, the power consumption of cement grinding is reduced, and the damage to the cement concrete caused by excessive chloride ions is avoided.
本发明适用于水泥助磨剂技术领域，提供一种用于水泥粉磨过程中的矿化料，由如下质量百分比的物质组成：硫酸钠2‑5％，硫代硫酸钠4‑7％，亚硫酸钠0‑3％，马来酸酐二聚酸三乙醇胺酯1‑3％，乙二醇1‑3％，粉煤灰79‑92％。通过确定合适的物质及含量，促使水泥早期水化作用，将水泥颗粒早期水化率大幅提高，以提高早期强度，并兼顾水化持久性，通过硫代硫酸钠、马来酸酐二聚酸三乙醇胺酯、乙二醇促使水泥后期水化作用，水泥浆体强度得以增长，并且还能包裹在水泥颗粒表面形成保护膜，消除粘结和吸附团聚，而马来酸酐二聚酸三乙醇胺酯能在金属表面形成氧化保护膜，阻滞钢筋锈蚀，本发明提高了磨机台时产量，并提高制品综合性能，降低水泥粉磨电耗，避免氯离子超标对水泥混凝土构成的危害。
