Description
Technical field
The invention belongs to additive technology field, specially a kind of cement additive suitable for municipal works.
Background technique
During cement additive refers to cement applications, to improve or realizing auxiliary agent that various characteristics are added, such as fastly
Dry or enhancing, such as water-reducing agent, reduce water content, such as retarder slow setting.In recent years, constantly pushing away with Process of Urbanization Construction
Into the problem of urban construction is brought increasingly shows.Wherein, due to the performance bring qualitative problems of construction of concrete also Shi Youfa
It is raw.
During concrete is applied in practical projects, various more harsh environment are commonly exposed to, as environment is corroded
Property medium intrusion, the variation of ambient temperature and humidity, Frozen-thawed cycled destroy and part concrete works are ground often in heavy load
Damage etc., these external conditions will seriously affect the service life of concrete.Therefore, it is necessary to protective agent pair is added in concrete
Concrete carries out protective effect, and existing concrete additive, which exists, to be had a single function, and uses a variety of different additives, Ke Yida
To different effects.But simultaneously collocation in use, if the interaction of various additives, type selecting, proportion or addition manner not
Correctly, it will seriously affect the construction quality of concrete.Cement water reducing agent is one of numerous additives of concrete, industry
Change and commercialization has pushed directly on the concrete technologies such as self-stressing concretes, self-compacting concrete, high-strength super high strength concrete
Development.It is composition indispensable in concrete material, and now on the market almost without being specially adapted for city's political and ideological work
The cement additive of journey, therefore it is proposed that a kind of cement additive suitable for municipal works.
Summary of the invention
It is an object of the invention to: there is no the cement of tailored version to solve to correspond to municipal works in existing cement additive
The problem of additive, provides a kind of cement additive suitable for municipal works.
The technical solution adopted by the invention is as follows:
A kind of cement additive suitable for municipal works, including following weight ratio raw material: gypsum 10~30%, palygorskite
Powder 5~15%, rice milk powder 5~10%, boron mud 1~10%, flyash 5~10%, aluminosilicate 1~10%, paraffin wax emulsions 5~
10%, diatomite 5~15%, cellulose ether 1~5%, water-reducing agent 5~10%.
Wherein, each raw material weight percentage are as follows: gypsum 25%, palygorskite 15%, Rice & peanut milk 10%, boron mud 5%, fine coal
Grey 10%, aluminosilicate 8%, paraffin wax emulsions 5%, diatomite 10%, cellulose ether 7%, water-reducing agent 5%.
Wherein, the gypsum selects ardealite, and ardealite is what the waste residue generated in chemical fertilizer factory's phosphoric acid producing process was produced
Gypsum.
Wherein, the water-reducing agent selects poly carboxylic acid series water reducer.
Wherein, the palygorskite powder is the powder material that natural palygorskite obtains after purification, modification.
Wherein, the rice milk powder is made after water logging, stewing steaming, water dissolution by rice.
Wherein, the rice milk powder is the dissolved slurries of water manufactured powder material after dry milling.
Wherein, the rice selects glutinous rice.
Wherein, a kind of cement additive suitable for municipal works, preparation method includes the following steps:
Step 1: by the weight ratio claim rice milk powder, cellulose ether and palygorskite powder are put into container, convert suitable quantity of water into
Row mixing, stirs evenly, obtains mixed liquor;
Step 2: claiming to obtain gypsum, boron mud, flyash and diatomite by the weight ratio, carry out grinding using flour mill, obtain
Mixed powder;
Step 3: mixed liquor and mixed powder being mixed, stirred evenly, and paraffin wax emulsions and manosil AS are added while stirring
Salt obtains mixture;
Step 4: rear grinding is dried in mixture;
Step 5: the weight ratio water-reducing agent is added and stirs evenly to get cement additive powdery finished product.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, in the present invention, the preparation method of cement additive, simple and easy, raw material is easy to get, cheap, to equipment and instead
Answer condition of less demanding, the cement after addition has the characteristics that preferable waterproof, crack resistence, high intensity and performance are stable.
2, in the present invention, by the way that palygorskite powder is added, is conducive to the emulsification and bonding between raw material, is added to energy in cement
Enough greatly increase the adhesive property, antistrip performance and waterproof effect of cement, at the same palygorskite powder also have preferable suspension,
Levelability and thickening property, and hence it is also possible to greatly reduce consumption of raw materials instead of original suspending agent, thickener and stabilizer
And cost of material.
3, the present invention in, by be added cellulose ether so that addition after cement have preferable high temperature performance and compared with
Good adhesion property, additionally it is possible to so that it with preferable crack resistance at low-temperature, is effectively prevented caused by being cracked as cement
Building tear, phenomena such as collapsing.
4, in the present invention, made cement additive overcomes and has a single function existing for conventional additive agent, and volume is big,
It improves and improves strength on concrete material, mobility, durability and the unconspicuous problem of anti-permeability performance effect, so that concrete material
Expect that intensity, mobility, durability and anti-permeability performance effect are more significant, volume is less, is plasticized the superior advantage of performance, can be obvious
Increase the slump of concrete, improves concrete cohesiveness and workability.
