Synergist for remarkably increasing mixing amount of low-activity admixture in cement and application
The invention discloses a synergist for remarkably increasing the mixing amount of a low-activity mixed material in cement and application, and solves the technical problem that in the prior art, a common cement grinding aid cannot play a proper role when being mixed into a mixed material with relatively low activity. The catalyst comprises 6-15% of a crystal nucleus component; 12%-20% of a complexing component; 12%-30% of an active excitation component; the crystal nucleus component comprises sodium polyacrylate, nano calcium carbonate and nano hydrated calcium silicate; the complexing component is any one or more of glucose, xylitol, mannitol, cane sugar and molasses; the active excitation component is an inorganic salt, and the inorganic salt is any one or more of lithium nitrate, lithium sulfate, aluminum chloride or aluminum sulfate. The synergist provided by the invention mainly aims at a low-activity admixture, and can effectively improve the activity of the admixture, so that the admixture can be more doped into cement, the clinker mixing amount is further reduced, and the synergist plays a role in more obviously consuming industrial waste residues and improving the cement quality in a cement plant.
本发明公开了一种显著增加水泥中低活性混合材掺量的增效剂及应用，解决了现有技术中常用水泥助磨剂在掺入活性较低的混合材时，往往不能发挥出应有作用的技术问题。它包括晶核组分：6%～15%；络合组分：12%～20%；活性激发组分：12%～30%；所述晶核组分包括聚丙烯酸钠、纳米碳酸钙和纳米水化硅酸钙；所述络合组分为葡萄糖、木糖醇、甘露醇、蔗糖和糖蜜中的任意一种或任意几种；所述活性激发组分为无机盐类，无机盐类为硝酸锂、硫酸锂、氯化铝或硫酸铝中的任意一种或任意几种。本发明提供的增效剂主要是针对低活性混合材，能够有效提高混合材的活性，使其能够更多掺入水泥中，进一步降低熟料掺量，为水泥厂更显著消耗工业废渣、提高水泥质量发挥作用。
