Abstract
The invention relates to a powder composite cement grinding additive comprising the following raw materials in percentage by weight: 4-10 percent of trolamine, 6-10 percent of trimeric sodium phosphate, 10-15 percent of mirabilite, 10-15 percent of anhydrous sodium sulphate, 5-15 percent of calcium sulphate and 35-65 percent of pulverized fuel ash. By adopting the invention, the addition amount of the grinding additive in the production of each ton of cement can be effectively reduced, the addition amount of mixed material and the utilization amount of the pulverized fuel ash can be effectively improved and the effects for saving energy and reducing consumption can be achieved, thereby the cement strength can be effectively improved, wherein the strength after three days can be improved by 2-3Mpa and the strength after 28 days can be improved by 3-6Mpa. Meanwhile, the invention also discloses a preparation method of the grinding addictive.
Description
Technical field
The present invention relates to field of cement production, relate in particular to a kind of powdery compound cement grinding aid and preparation method thereof.
Background technology
Grinding aid in the market mainly is divided into pulvis, liquid.The characteristics of liquid grinding aid are that accumulating and interpolation are convenient, and shortcoming is that cost is relatively high.The characteristics of pulvis grinding aid are that cost is low, but consumption is large, and great majority contain the chlorion that endangers cement quality.
Summary of the invention
Technical problem to be solved by this invention provides the powdery compound cement grinding aid of a kind of not chloride ion-containing, Effective Raise flyash utilization.
Another technical problem to be solved by this invention provide a kind of technique simply, the preparation method of the powdery compound cement grinding aid that effectively reduces production costs.
For addressing the above problem, a kind of powdery compound cement grinding aid of the present invention is characterized in that: this grinding aid is comprised of the raw material of following mass percent: trolamine 4～10%, tripoly phosphate sodium STPP 6～10%, mirabilite 10～15%, Sodium sulfate anhydrous.min(99) 10～15%, calcium sulfate 5～15%, flyash 35～65%.
The preparation method of aforesaid a kind of powdery compound cement grinding aid may further comprise the steps:
(1) by each raw material of proportioning weighing;
(2) respectively mirabilite, calcium sulfate and flyash are ground, and cross 400 * 400 eye mesh screens, obtain mirabilite powder, sulfuric acid calcium powder and fine coal ashes;
(3) described mirabilite powder, sulfuric acid calcium powder are inserted in the airtight stirrer and stirred, after mixing, add first tripoly phosphate sodium STPP, Sodium sulfate anhydrous.min(99) and described fine coal ashes and stir, after evenly, add again trolamine and stir, after mixing and get final product.
The present invention compared with prior art has the following advantages:
1, because therefore the present invention's chloride ion-containing not, has avoided the appearance of harm cement quality phenomenon effectively, can guarantee the work-ing life of Steel Concrete.
2, owing to being added with tripoly phosphate sodium STPP among the present invention, therefore, can effectively help grog to grind, improve the addition of blended material and the specific surface area of cement, put forward the effect of producing and strengthening thereby reach.
3, behind use the present invention, not only the addition of grinding aid is effectively reduced in manufacture of cement per ton, and addition that can the Effective Raise blended material, while Effective Raise flyash utilization, reach energy-saving and cost-reducing effect, thereby effective raising strength of cement, intensity improved 2～3Mpa in three days, and intensity can improve 3～6Mpa in 28 days.
4, through the reality test, the present invention can improve the production efficiency of cement, can improve cement mill unit-hour output 10%～20% (referring to table 1) in 0.5% situation of the present invention of adding; Strength of cement effectively improves simultaneously.
Salient features index contrast table before and after table 1 the present invention uses
Certain cement production enterprise
5, because the present invention adopts the mode of simple mixing to be prepared, therefore, not only technique is simple, and has effectively reduced production cost.
