Abstract
The invention discloses a novel cement grinding aid and a cement thereof, and belongs to the field of cement production. The cement grinding aid is produced from, by weight, 6-12 parts of a hydramine substance, 3-8 parts of sodium polycarboxylate, 4-6 parts of sodium dodecyl sulfonate, 4-8 parts of diatomite, 4-8 parts of saturated fatty acids, 3-5 parts of hydroxyethyl cellulose, 3-5 parts of molasses and 4-8 parts of calcium formate. The invention also discloses the cement including the cement grinding aid. The cement grinding aid has the advantages of low admixture amount, good enhancement effect, improvement of the performances of cement and the output per machine hour, and reduction of the production cost of the cement, and the cement produced by using the cement grinding aid has the advantages of small clinker proportion, reduction of environment pollution, and saving of mineral product resources.
Description
Technical field
The present invention relates to a kind of novel concrete grinding aid and its cement, belong to cement and manufacture field.
Background technology
Cement is indispensable a kind of construction material in human lives and social production, and its range is wide, and consumption is big,
Have " title of the grain of building industry ".But, cement production industry pollution is big, and energy resource consumption is big.In order to energy-saving, most preferably
Approach is exactly interpolation cement grinding aid in grinding process, on the one hand, cement grinding aid can improve product during the platform of cement mill
Amount, thus directly reduce grinding pow consumption；On the other hand, cement grinding aid can also excite the activity of industrial residue, reduces water
The usage amount of mud grog, thus saving the coal causing because producing clinker, electric consumption, and reduces atmosphere pollution
Discharge, improves the utilization ratio of industrial residue so as to resource efficiency improves, while realizing " energy-conservation " effect, also reaches
Arrive the purpose of " reduction of discharging ".
At present the component of China's grinding aid product generally existing always is single, with high costs, product quality stability is poor, right
The not good popularization and application waiting defective effect grinding aid of process conditions adaptability, therefore need badly by experimental study, develop a class tool
It is standby that grinding-aid effect is excellent, with low cost, properties of product are stable, high the having concurrently of universality is improved cement physical properties, excites mixing material
Activity, the multi-functional composite grinding aids of raising blending amount of mixture material.
Content of the invention
The purpose of the present invention is to make up the deficiencies in the prior art, provides a kind of novel concrete grinding aid and its cement.This
Bright cement grinding aid, volume is low, reinforced effects are good, can improve cement performance and unit-hour output, using the grinding aid of the present invention
The cement that agent produces, grog proportioning is few, low production cost, can reduce environmental pollution, saves mineral resources.
The technical scheme is that a kind of novel concrete grinding aid, by following weight portion
The raw material of number is made: 6～12 parts of alcaminess material, 3～8 parts of polybasic carboxylic acid sodium, 4～6 parts of dodecyl sodium sulfate, kieselguhr 4
～8 parts, 4～8 parts of satisfied fatty acid, 3～5 parts of hydroxyethyl cellulose, 3～5 parts of molasses, 4～8 parts of calcium formate.
On the basis of technique scheme, the present invention can also do following improvement.
Further, it is made up of the raw material of following parts by weight: 9 parts of alcaminess material, 5 parts of polybasic carboxylic acid sodium, dodecyl
5 parts of sodium sulfonate, 6 parts of kieselguhr, 6 parts of satisfied fatty acid, 4 parts of hydroxyethyl cellulose, 4 parts of molasses, 6 parts of calcium formate.
Further, described alcaminess material is ethanolamine, diethanolamine, triethanolamine, triisopropanolamine, diethanol list second
One of hydramine, diisopropyl ethanolamine.
A kind of cement comprising as above cement grinding aid described in any one.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the quality of described grinding aid is 0.05～0.09wt% of cement quality.
Further, the quality of described grinding aid is the 0.07wt% of cement quality.
The invention has the beneficial effects as follows:
(1) cement grinding aid of the present invention, volume is low, reinforced effects are good, can improve cement performance and unit-hour output, fall
The cost of low manufacture of cement.
(2) adopt the cement that the grinding aid of the present invention produces, grog proportioning is few, low production cost can reduce environmental pollution,
Save mineral resources.
(3) cheap, the simple production process of the present invention, suitable large-scale production.
