Abstract
The invention discloses a kind of using slag as the preparation method of the cement-base composite material of admixture, comprise the following steps:Mix preparation is prepared first, and pretreatment slag micro powder is made in itself and slag mixing and ball milling;Montmorillonite and Cetyltrimethylammonium bromide and hexamethylene are mixed, then the CNT of carboxylated is added, obtain CNT intercalated montmorillonite material, finally cement, pretreatment slag micro powder, CNT intercalated montmorillonite material, flyash, wollastonite in powder, gypsum, natural river sand are mixed evenly, and addition is by the mixture of water reducer, defoamer, swelling agent, dispersant and deionized water, cement base mixed slurry is made after well mixed, add it in mould, jolt ramming is molded, demoulding maintenance, is made cement-base composite material.This method is cheap using slag as raw material, and pretreated slag gelation activity is big, and composite material strength is big, and mechanical property is good.
Description
Technical field:
The present invention relates to building material field, it is specifically related to a kind of using slag as the cement-base composite material of admixture
Preparation method.
Background technology:
Slag is the solid waste produced in steel smelting procedure, based on its mineral composition silicate phase, with potential
Gelling property, its discharge rate is about the 15-20% of crude steel yield.The density of slag is between 3.3-3.6g/cm3Between, from table
From the point of view of on face, steel slag particle connection is more open, and quality is hard.Because Fe content is high, cause steel slag grinding relatively difficult, steel
Being of grindability index 7 of slag, the grindability index 1.0 of grindability indexization 96, normal sand less than blast-furnace cinder.
Developed country, the overall utilization rate Hen Waterloo of slag, almost close to 100%, but developed country is in cement and coagulation
Utilization rate in terms of native product is very low.The slag that Germany produces in steel-making, although its utilization rate is very high, is mostly treated as
Gather materials and use, an only small part slag is used for cement products:And the U.S. comes before nineteen ninety merely with 1% slag raw material
Manufacture cement.In Chinese slag (mainly vessel slag) cumulant more than 30,000,000,000 tons, but these slags whole utilization level not
It is high.Consider from the resource and validity angle of slag, the utilization rate of slag is about 36%, approximate 10% or so slag
It is utilized in building materials field, in terms of about 3% is used for cement.Therefore, the utilization rate for improving slag is to realize steel enterprise of China
The important channel of industry sustainable development.But free oxidation in slag is skilful, the hydration process of magnesia can cause slag cement
The expansion of composite gelled material volume, causes the less stable of system;And the fluctuation of its composition is big, early strength is low, causes
Its application in cement-based material is by limitation.
The content of the invention:
The purpose of the present invention is to disclose a kind of preparation method using slag as the cement-base composite material of admixture, and this is combined
The slag that material is used is cheap, and the slag gelation activity after processing is big, and wearability is good, and the obtained strength of materials is big, mechanics
Performance is good.
To achieve the above object, the present invention uses following technical scheme:
It is a kind of using slag as the preparation method of the cement-base composite material of admixture, comprise the following steps:
(1) calcium salt or sodium salt, polyhydric alcohol amine hydrochloride and water are mixed into solid dissolving, obtains solution A;By binary
After alcoholic compound, organic alcohol amine compound are mixed evenly, glacial acetic acid is added, obtained solution B is mixed;By solution A and
Solution B, which is mixed, is made mixed liquor, and is added to slag in ball mill, ball milling 1-2h, and ball milling is dried after terminating, system
Slag micro powder must be pre-processed;
(2) montmorillonite, Cetyltrimethylammonium bromide and hexamethylene are added in three-necked flask and are mixed evenly,
50-80 DEG C is warming up to, then constant temperature stirring 20-40min adds carboxylic carbon nano-tube, be warming up to 100 DEG C, flow back 2-4h, knot
Room temperature is cooled to after beam, is filtered, dries, obtains CNT intercalated montmorillonite material;
(3) by CNT intercalated montmorillonite made from cement, the obtained pretreatment slag micro powder of step (1), step (2)
Material, flyash, wollastonite in powder, gypsum, natural river sand are mixed evenly, and obtain mixed material;By water reducer, defoamer,
Swelling agent, dispersant and deionized water are mixed evenly, and add it in said mixture material, are made after being well mixed
Cement base mixed slurry,
(4) finally cement base mixed slurry obtained above is added in mould, vacuumizes blebbing, jolt ramming shaping, 24
Fog room is put into after the hour demoulding to conserve 15-30 days, and cement-base composite material is made.
As the preferred of above-mentioned technical proposal, in step (1), calcium salt or sodium salt, polyhydric alcohol amine hydrochloride, binary alcohol compound
Thing, organic alcohol amine compound, glacial acetic acid, water consumption in parts by weight, be specially:Calcium salt or 10-20 parts of sodium salt, polyhydric alcohol amine
2-10 parts of hydrochloride, 5-20 parts of diatomic alcohol compounds, 3-10 parts of organic alcohol amine compound, 0.1-2 parts of glacial acetic acid, 45-60 parts of water.
As the preferred of above-mentioned technical proposal, in step (1), the calcium salt is one kind in calcium acetate, calcium formate;It is described
Sodium salt is one kind in sodium acetate, sodium formate, sodium thiosulfate.
As the preferred of above-mentioned technical proposal, in step (1), the diatomic alcohol compounds are triethylene glycol, Isosorbide-5-Nitrae-fourth two
One or more mixing in alcohol, neopentyl glycol.
As the preferred of above-mentioned technical proposal, in step (1), the polyhydric alcohol amine hydrochloride be triethanolamine hydrochloride and
