Abstract
The invention relates to a cement additive for reducing the dosage of cement clinker, belonging to the technical field of the cement clinkers in cement production. The cement additive comprises the following raw materials in parts by weight: 50-60 parts of water, 12-18 parts of sodium chloride for industrial use, 2.5-4 parts of sucrose, 4-5 parts of sodium lignin sulfonate, 8-12 parts of triethanolamine and 5-15 parts of silicon powder. When the formula of the cement additive provided by the invention is used for producing cement, only is 0.1% of the cement additive added, so that 8-12% of dosage of the cement clinker can be reduced, the yield of a mill can be improved by 10-15%, and the production cost of each ton of cement can be comprehensively reduced by 15-20 yuan.
Description
Technical field
The present invention relates to a kind of cement additire, more particularly, the present invention relates to a kind of cement additire for reducing cement clinker consumption, belong to the cement additire technical field in the manufacture of cement.
Background technology
Cement additire is external appellation, and cement additire and cement additive all refer to cement grinding aid at home.Cement additire is a kind of chemical additive that improves cement grinding effect and performance, can significantly improve each age strength of cement grinding mill unit-hour output and cement.Cement additire can reduce the electrostatic adhesion bag ball phenomenon that forms in the grinding process significantly, and can reduce the coalescent trend again of the ultra-fine grain that forms in the grinding process, reduces the grinding phenomenon.Cement additire also can significantly improve cement flows, improves the mill efficiency of grinding machine and the grinding efficiency of powder separating machine, thereby reduces the grinding energy consumption.As a kind of chemical activator, cement additire can improve the hydration activity that cement granules distributes and excites each blended material, thereby improves cement early strength and later strength.
It is CN102432209A that State Intellectual Property Office discloses a publication number in 2012.5.2, name is called the patent of invention of " additive and the preparation method of the energy-conservation and synergy of a kind of suitable manufacture of cement ", this patent disclosure the additive of the energy-conservation and synergy of a kind of suitable manufacture of cement, it is characterized in that adopting following component and weight percent content: trolamine 60%-80%, second one hydramine 8%-12%, sodium polyacrylate 0.5%-3%, 12-alkyl sodium sulfonate 0.5%-3%, rosin fat 0.5%-1.5%, nickel salt 0.5%-2.5%, water 10%-18%.The major advantage of this additive: 1, the unit-hour output that improves raw mill and coal mill is respectively saved its grinding pow consumption more than 10% more than 10%.2, save the consumption of coal in the cement production process more than 8%.3, improve the output of grog more than 8%.4, improve each age strength 2-5MPa of grog, and can improve the stability of grog.5, improve the overall economic efficiency of grog more than 10 yuan/ton.6, reduce discharging manufacture of cement CO
2And SO
3Each is more than 8%.
Though above-mentioned cement additire of the prior art can improve the output of cement clinker, and accomplish certain energy-saving and emission-reduction, but still exist in the subsequent preparation cement link, need to use a large amount of cement clinkers, and binder component complexity, the additive usage quantity is big in process of production, the problem that cost is high.
Summary of the invention
After the present invention is intended to solve above-mentioned cement additire of the prior art and uses in manufacture of cement, still need a large amount of cement clinkers to prepare cement, and the add-on of additive own is big, the high problem of the complicated cost that causes of component, a kind of cement additire for reducing cement clinker consumption is provided, this cement additive components advantages of simple reaches and reduces manufacture of cement cost purpose.
In order to realize the foregoing invention purpose, its concrete technical scheme is as follows:
A kind of cement additire for reducing cement clinker consumption is characterized in that: comprise following raw material according to the parts by weight meter:
Water 50-60 part
Industry sodium-chlor 12-18 part
Sucrose 2.5-4 part
Sodium lignosulfonate 4-5 part
Trolamine 8-12 part
