Abstract
The invention discloses a special grinding aid for phosphorus slag cement. The special grinding aid consists of the following components in parts by weight: 20-25 parts of diethanolisopropanolamine, 15-20 parts of a phosphorus slag active excitant, 5-10 parts of a masking agent and 50-75 parts of water. As the formula of the grinding aid is adjusted, that is, industrial salt in a conventional grinding aid is replaced by the phosphorus slag active excitant (the content is somehow increased), and moreover honey with a coagulation delay function is removed, so as to obtain the novel grinding aid. Due to the phosphorus slag active excitant in the grinding aid, after cement is added with water, the phosphorus slag active excitant starts to be hydrolyzed to form calcium aluminosilicate and calcium sulfoaluminate, meanwhile the pH value of cement slurry can be increased, and Si-O-Si chemical bands in a phosphorus slag vitreous body can be promoted to be broken, hydration of the phosphorus slag cement is accelerated, and the early strength enhancing rate of the phosphorus slag cement can be increased.
Description
Technical field
The present invention relates to a kind of phosphoric slag cement grinding aid special.
Background technology
For employing the phosphorus slag cement as mixing material, due to the inherent character of phosphorus slag, phosphorus slag can be caused
Cement setting time length, early strength enhancement rate is on the low side.Existing grinding aid can improve phosphorus to a certain extent
The early strength of slag cement, but it is without the even negative contribution of contribution shortening on setting time.During condensation
Between this shortcoming long result in phosphoric slag cement and be generally out of favour in work China Democratic National Construction Association field so that the pin of phosphoric slag cement
The amount of selling never has bigger breakthrough.
Summary of the invention
The present invention proposes a kind of phosphoric slag cement grinding aid special, shortens the setting time of phosphoric slag cement, carries
Its early strength enhancement rate high.
A kind of phosphoric slag cement grinding aid special, is made up of following weight portion: diethanol monoisopropanolamine 20-25
Weight portion, reactivity of phosphor slag exciting agent 15-20 weight portion, screening agent 5-10 weight portion and water 50-75 weight portion.
Preferably, during described reactivity of phosphor slag exciting agent is sodium silicate/potassium, sodium aluminate/potassium and sodium sulfate/potassium at least
A kind of.
Preferably, described screening agent is at least one of phosphate radical and fluorion sodium/potassium salt.
The present invention is adjusted on the formula of grinding aid, substituted for former grinding aid with reactivity of phosphor slag exciting agent
In Nacl (content has increased), and eliminate the molasses with deferred action, thus obtain one
Novel aid grinding agent.This grinding aid is because containing reactivity of phosphor slag exciting agent, when after cement plus water, and activity excitant
Start to hydrolyze to form ca aluminosilicate and calcium sulphoaluminate, make cement slurry pH value increase simultaneously, promote phosphorus slag glass
Si-O-Si chemical bond rupture in body, thus accelerate the aquation of phosphoric slag cement, improve phosphoric slag cement in early days
Intensity enhancement rate.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, technical scheme is clearly and completely described, aobvious
So, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly fall into the scope of protection of the invention.
Embodiment 1:
It is made up of following weight portion: diethanol monoisopropanolamine 20kg, the reactivity of phosphor slag exciting agent (silicic acid all measured
Sodium, potassium aluminate and sodium sulfate) 20kg, screening agent (sodium fluoride) 7kg and water 50kg, mixed by conventional method
Grinding aid is made in conjunction.
Embodiment 2:
It is made up of following weight portion: diethanol monoisopropanolamine 25kg, reactivity of phosphor slag exciting agent (sodium silicate)
15kg, screening agent (sodium fluoride) 5kg and water 75kg, be mixed and made into grinding aid by conventional method.
Embodiment 3:
It is made up of following weight portion: diethanol monoisopropanolamine 22kg, reactivity of phosphor slag exciting agent (sodium aluminate)
18kg, screening agent (potassium phosphate) 10kg and water 60kg.
By above-described embodiment, conventional commercially available grinding aid, carry out phosphoric slag cement without in the case of grinding aid three kinds
Condensation situation compare (data such as following table):
Table 1 grinding aid Contrast on effect
Based on above table, this grinding aid is because containing reactivity of phosphor slag exciting agent, when after cement plus water, active
Exciting agent starts to hydrolyze to form ca aluminosilicate and calcium sulphoaluminate, makes cement slurry pH value increase simultaneously, promotes phosphorus
Si-O-Si chemical bond rupture in slag vitreous body, thus accelerate the aquation of phosphoric slag cement, improve phosphorus slag water
Mud early strength enhancement rate.Activity excitant is added in the cement grinding stage in advance as grinding aid composition,
It can be made to be distributed in more uniformly in cement, enhance the stability of phosphoric slag cement quality.Relative to making
Use former grinding aid, after cement production enterprise uses this grinding aid, shorten the time of phosphoric slag cement condensation, improve
Its early strength enhancement rate, can make the phosphoric slag cement usage amount in work China Democratic National Construction Association field be greatly increased；Phosphorus slag water
The increase of mud consumption accelerates again the comprehensive utilization of phosphorus slag, decreases the pollution of appropriation of land and environment, society
Meeting benefit is inestimable.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
