Cement and production process thereof
The invention discloses cement and a production process thereof. The invention relates to the technical field of building materials. The cement is prepared from the following raw materials in parts byweight: 56-71 parts of clinker, 3-8 parts of fly ash, 5-11 parts of saltpeter, 0.2-0.4 part of modified alkali lignin and 11-35 parts of mineral powder, and the modified alkali lignin is prepared bycatalytic degradation of a phosphotungstic acid and hydrogen peroxide mixed system and activation of the alkali lignin. Due to the addition of the modified alkali lignin, the modified lignin is adsorbed on the surface of the ground material, and the attraction among material particles is reduced, so that the ground material is not easy to agglomerate, and the purpose of improving the grinding efficiency of the cement is achieved; the invention also provides a production process of the cement. The production process has the advantage of improving the mixing uniformity of the raw materials.
本发明公开了一种水泥及其生产工艺，涉及建筑材料的技术领域，一种水泥，包括以下重量份的原料制成：56‑71份的熟料、3‑8份的粉煤灰、5‑11份的石硝、0.2‑0.4份的改性碱木质素以及11‑35份的矿粉，所述改性碱木质素通过磷钨酸与过氧化氢混合体系催化降解并活化碱木质素制成。改性碱木质素的加入，使得改性木质素吸附在磨细的物料表面，减小了物料颗粒之间的吸引力，从而使得粉磨好的物料不易团聚，从而实现提高水泥的粉磨效率的目的；本发明还提出了一种水泥的生产工艺，其具有提高原料混合均匀性的优点。
