Description
Technical field
The invention belongs to cement additive technical field, particularly to a kind of enhanced cement grinding aid.
Background technology
Cement grinding is the necessary operation in manufacture of cement and key link, and its energy consumption and power consumption account for manufacture of cement total energy consumption
30% and total power consumption more than 70%, currently, country's low-carbon environment-friendly require more and more higher, cement price is dispirited, raw material and energy
Source price appreciates, and industry competition is white-hot, makes the benefit of cement production enterprise have too many difficulties to cope with.So energy-saving and emission-reduction, develop low-carbon economy,
Reduce cost, improve grinding aid performance, be the urgent problem highly necessary solved of cement industry.For reducing energy consumption, improve mill efficiency, people
Measure following two in terms of be usually taken: one, improve milling equipment and grinding process to utilize mechanical energy to greatest extent；
Two, cement pulverizing course adds cement grinding aid and improves mill efficiency.Wherein the second measure is current manufacture of cement
The research emphasis in field.
In developed countries such as America and Europe, Japan, the use of grinding aid is the most fairly common, and we are also at the early-stage
Stage.The existing grinding aid of China in use still suffers from a lot of problem, as villaumite brings to the durability of cement and concrete
The biggest potential safety hazard；Grinding aid quality is unstable, and volume is big, thus causes cement quality fluctuation etc..In prior art, cement
The outstanding feature using triethanolamine amine in grinding aid is to improve 1 day cement mortar strength of cement, but for 28 days and the strongest
Degree not contribution；A lot of cement grinding aids are also selected triethanolamine to strengthen 7 days of cement, 28 days or later intensity, but
Triethanolamine can not increase the early strength within 1 day or 7 days of cement.
Therefore a kind of enhanced cement grinding aid of research and development, fundamentally solves the drawback that tradition grinding aid exists, is
The urgent needs of this area and study hotspot.
Summary of the invention
The technical problem to be solved is to provide a kind of enhanced cement grinding aid, this grinding aid grinding effect

10 parts of sodium of acid, 60 parts of water.
Preferably, the present invention is when preparing enhanced cement grinding aid, and described temperature is 45 DEG C.
Preferably, the present invention, when preparing enhanced cement grinding aid, stirs 45min.
Compared to existing technology, the beneficial effects of the present invention is:
1, the enhanced cement grinding aid of the present invention has a good grinding effect, mill hourly output improve 29～
38%.
2, the enhanced cement grinding aid of the present invention can improve 7d and 28d bending and compressive strength, wherein 3d rupture strength
Improve 22～34%, 3d comprcssive strength 18～26%, 28d rupture strength improve 21～29%, 28d comprcssive strength improve 25～
36%.
3, the enhanced cement grinding aid of the present invention is conducive to the raising of maturing anti-blending freezing and thawing performance, wherein
Through measuring, mixing the cement of grinding aid of the present invention when preparing concrete, freeze thawing resistance cycle-index can reach 250 times.
4, the enhanced cement grinding aid plastication of the present invention is strong, is keeping the ratio of mud and the constant situation of cement consumption
Under, the slump can be brought up to 12～20cm by 5～7cm, and the 60min slump is not lost.
