Description
Technical field
The present invention relates to a kind of cement.
Background technology
Cement is a kind of powdery hydraulicity inorganic coagulation material, add water stir after at slurry, can harden in air or
Preferably hardening in water, and can the materials such as sand, stone are cemented together securely, it is a kind of important cementitious material, and
It is widely used in the engineering fields such as civil construction, water conservancy, national defence, there are many type of cement, can be divided by its purposes and performance logical
With cement, cement special and characteristic cement three categories.With the construction of the development and city of society, the consumption of cement is increasingly
Greatly, white elephant is brought to environment, in order to energy saving, a kind of cement using waste production of development is imperative.
Invention content
In order to solve the above technical problems, technical solution provided by the invention is：A kind of cement, it includes following mass parts
Raw material：300~500 parts of clinker, 200~500 parts of mixing material, 20~60 parts of fluorgypsum, 0.2~0.4 part of ethanol amine, three ethyl alcohol
Amine, 0.2~0.4 part, 0.3~0.5 part of triisopropanolamine, 1~3 part of sodium sulphate, 3~5 parts of water-reducing agent, cellulose ether 0.5~2
Part, 50~150 parts of montmorillonite.
The mixing material includes the raw material of following mass parts：50~100 parts of powdered coal cinder, bulky grain river sand 50~100
Part, 50~100 parts of little particle river sand, 50~100 parts of slag, 50~100 parts of clinker.
As an improvement, it includes the raw material of following mass parts：350~450 parts of clinker, 250~450 parts of mixing material, fluorine
30~50 parts of gypsum, 0.2~0.3 part of ethanol amine, triethanolamine, 0.2~0.3 part, 0.3~0.45 part of triisopropanolamine, sulfuric acid
2~3 parts of sodium, 3~4 parts of water-reducing agent, 0.5~1.5 part of cellulose ether, 60~120 parts of montmorillonite.
The mixing material includes the raw material of following mass parts：60~90 parts of powdered coal cinder, 60~80 parts of bulky grain river sand,
60~80 parts of little particle river sand, 60~85 parts of slag, 50~90 parts of clinker.
As an improvement, 400 parts of clinker, 400 parts of mixing material, 40 parts of fluorgypsum, 0.25 part of ethanol amine, triethanolamine,
0.25 part, 0.4 part of triisopropanolamine, 2 parts of sodium sulphate, 3.8 parts of water-reducing agent, 1 part of cellulose ether, 80 parts of montmorillonite.
The mixing material includes the raw material of following mass parts：80 parts of powdered coal cinder, 75 parts of bulky grain river sand, little particle river
70 parts husky, 80 parts of slag, 85 parts of clinker.
Ethanol amine is the general name of monoethanolamine (MEA), diethanol amine (DEA), triethanolamine (TBA), it is as epoxy second
Important one of the derivative of alkane, is product most with practical value in amino alcohol, yield account for amino alcohol total output 90%~
95%, there are nitrogen-atoms and hydroxyl in ethanolamine molecules, therefore has the chemical property of amine and alcohol concurrently.Ethanol amine is not only a kind of good
Grinding aid, and be cement intensifier and lubricant；
Triethanolamine i.e. three (2- ethoxys) amine, can regard the trihydroxy substituent of triethylamine as, with other amines
It is similar to close object, since there are lone pair electrons, triethanolamine to have alkalescent on nitrogen-atoms, can be given birth to inorganic acid or organic acid reaction
At salt.The alkalinity of triethanolamine is weaker than ammonia, the property with tertiary amine and alcohol.Salt is generated when with organic acid reaction low temperature, when high temperature
Generate ester.Triethanolamine is added in cement, reacts with other substances in cement, consumes a large amount of water, and can send out very
More heats allow for the moisture in cement and tail off because reaction and evaporation is participated in, improve the water-cement ratio of cement, improve in this way
The compactness of cement, just improves hardness；
Triisopropanolamine can not only improve grinding efficiency, reduce energy consumption, and can increase strength of cement；
Sodium sulphate is the salt that sulfate radical is generated with sodium ion chemical combination, and sodium sulphate is dissolved in water and its aqueous solution is in alkalescent, molten
Ethyl alcohol is not dissolved in glycerine, the addition of sodium sulphate makes hydrated product calcium sulphoaluminate quickly generate, to accelerate cement
Hydration and hardening speed；
Cellulose ether is formed by the etherification reaction and dry grinding of one or more of etherifying agents by cellulose, is being constructed
In the process, mortar carries out hydration reaction without time enough and moisture, leads to cement slurry after hardening often since dehydration is too fast
There is phenomena such as intensity deficiency and cracking.Cellulose ether is a kind of common polymeric additives in dry-mixed mortar, it, which has, protects
The effects that water, thickening, slow setting and bleed, can be obviously improved the performance of mortar；
Montmorillonite is nontoxic, nonirritant, has good water solubility, will not hydrolytic spoilage.And have well with Multicomponent
Intermiscibility.Used as main raw material(s) in polycarboxylic acid series cement water reducer, the efficient based water reducer of polycarboxylic acids of synthesis have compared with
Strong cement granules dispersibility holding capacity, have volume is low, water-reducing rate is high, enhancing effect is good, durability, not Corrosion Reinforcement and
The features such as environmentally friendly.
The present invention is by largely using mixing material, i.e., various slag waste residues waste residue utilization rate to be improved, by various
Effective additive is used cooperatively so that strength of cement is high, compactness is high, usage time is permanent.
