Abstract
The invention relates to a novel cement grinding aid. The cement grinding aid is characterized by comprising components in parts by weight as follows: 20-30 parts of triethanolamine, 5-10 parts of sodium thiosulfate, 2-6 parts of aluminum sulfate, 8-10 parts of maleic anhydride, 2-6 parts of ethylene glycol, 6-12 parts of sodium lignosulphonate, 8-12 parts of ethylparaben, 10-15 parts of calcium formate, 1-4 parts of an initiator, 6-10 parts of sodium chloride, 6-8 parts of urea, 2-6 parts of fly ash and 5-10 parts of molasses. The cement grinding aid has the effects of significantly improving the cement grinding efficiency of a mill by 8%-15%, properly improving the early strength of the cement by 2-3 MPa and enhancing the later strength of the cement by 2-4 MPa; all the components cooperate with one another, the adaptability of the grinding aid is improved, so that the grinding aid is applicable to different classes of cement, the usage range is enlarged, the grinding aid effect is greatly improved, the output per machine-hour is also increased, the power consumption is reduced, and the mixing amount is low and is 0.02%-0.06% per ton of cement.
Description
Technical field
The present invention relates to a kind of novel concrete grinding aid.
Background technology
Cement industry is resource consumption rich and influential family, not only consumes the mineral wealth such as Wingdale in a large number, and huge to coal equal energy source resources requirement, and Cement industry is faced with severe resource problem.Under the large policy environment of national sustainable development, in manufacture of cement, the energy-saving and emission-reduction work of links is gradually by people are paid attention to, and cement grinding aid is the important ring in cement industry chain, remarkable effect is had to carrying product consumption reduction, for cement production enterprise brings huge economic benefit, thus cement grinding aid becomes study hotspot gradually.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of novel concrete grinding aid.
Described a kind of novel concrete grinding aid, is characterized in that being made up of the component of following weight part: trolamine 20-30, Sulfothiorine 5-10, Tai-Ace S 150 2-6, maleic anhydride 8-10, ethylene glycol 2-6, sodium lignosulfonate 6-12, ethyl p-hydroxybenzoate 8-12, calcium formiate 10-15, initiator 1-4, sodium-chlor 6-10, urea 6-8, flyash 2-6, molasses 5-10.
Described a kind of novel concrete grinding aid, is characterized in that being made up of the component of following weight part: trolamine 24-26, Sulfothiorine 6-8, Tai-Ace S 150 3-5, maleic anhydride 8.5-9.5, ethylene glycol 3-5, sodium lignosulfonate 8-10, ethyl p-hydroxybenzoate 9-11, calcium formiate 12-14, initiator 2-3, sodium-chlor 7-9, urea 6.5-7.5, flyash 3-5, molasses 6-8.
Described a kind of novel concrete grinding aid, is characterized in that being made up of the component of following weight part: trolamine 25, Sulfothiorine 7, Tai-Ace S 150 4, maleic anhydride 9, ethylene glycol 4, sodium lignosulfonate 9, ethyl p-hydroxybenzoate 10, calcium formiate 13, initiator 2.5, sodium-chlor 8, urea 7, flyash 4, molasses 7.
Combination formula of the present invention uses the present invention to have the effect of the later strength improving cement further, the mill grinding efficiency 8%-15% of cement can be improved significantly, the effect of suitable raising cement early strength 2-3MPa and increase cement later strength 2-4MPa, and this combination formula containing any objectionable constituent, does not meet environmental requirement; Each component is worked in coordination with mutually, improves the adaptability of grinding aid, and to be applicable to the cement of different grades, increase use range, grinding-aid effect improves greatly, also improves unit-hour output, reduce energy consumption, and volume is low, is 0.02-0.06%/ton cement.
