Abstract
The invention discloses a rapid-even stirring magnesium oxide concrete external doping method, which comprises the following steps: putting water, dried material of magnesium oxide and additive in the water-weighing hopper, stirring mechanically or pneumatically to prepare composite liquid of magnesium oxide, adding in the stirrer to mix with concrete and sand, stone and cement, stirring to obtain the external doped magnesium oxide concrete.
Description
Affiliated technical field
The present invention relates to the water conservancy project dam concrete construction, particularly a kind of method of fast and equably mixing concrete with added magnesium oxide.
Background technology
The concrete with added magnesium oxide dam construction technique has begun to apply, and the good and bad key of its construction quality of building a dam is the uniformity of mixed magnesia in concrete.At present, mixed magnesia is mixed the most directly input magnesia siccative in mixer that adopts of mixed magnesia in the system Concrete Construction process.Because the magnesia quantity that every mixed concrete mixes at home and abroad seldom is difficult for evenly distributing, therefore, need reach its concrete with added magnesium oxide uniformity by prolonging mixing time, cause mixer production efficiency significantly to reduce, construction cost rises.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art and a kind of method of mixing system concrete with added magnesium oxide speed that significantly improves is provided; By adopting even dispersion method of density and volume amplifying method; Both become the mixed magnesia siccative and be the mixed magnesia mixed liquor, realized that the magnesia siccative evenly disperseed, bulk form is amplified in water and additive solution, and made fast and equably mixing concrete with added magnesium oxide become possibility.
The object of the present invention is achieved like this:
A kind of method of fast and equably mixing concrete with added magnesium oxide: comprise to water claiming that bucket aborts in (stirred vessel), magnesia siccative, additive, in water claims bucket (stirred vessel), making the magnesia mixed liquor earlier with mechanical agitation or pneumatic stirring, dropping into the mixer inner concrete again mixes and stirs in material, (sand, stone, cement), then mix the concrete of making mixed magnesia, it is characterized in that sending in the mixer is with mechanical agitation or the pneumatic magnesia mixed liquor that stirs; Tool stirs or pneumatic stirring keeps normally open.
---described magnesia mixed liquor is the mixed liquor of water, magnesia and additive.
---described mechanical agitation or pneumatic stirring keep normally open, are to prevent that magnesia mixed liquor precipitation from taking place.
Principle of the present invention adopts even dispersion method of density and volume amplifying method, becomes the mixed magnesia siccative and is the mixed magnesia mixed liquor; And using mechanical agitation or pneumatic stirring process, the mixed magnesia mixed liquor that guarantees to send in the mixer keeps evenly, thereby reaches the purpose of fast and equably mixing concrete with added magnesium oxide.
Marked improvement of the present invention and beneficial effect are the production efficiency that has improved mixer greatly, shorten the engineering time, reduce construction cost.
Description of drawings
Fig. 1 is that a kind of magnesia mixed liquor of the present invention is mixed the system system layout.
Fig. 2 is a process chart of the present invention.
Among the figure: 1 for claiming to struggle against, 9 be to supply the magnesia screw machine for magnesia for air supply pipe, 8 for mechanical agitator, 7 for mixture export pipe, 6 for water claims bucket (stirred vessel), 5 for feed pipe, 4 for additive claims bucket, 3 for additive pipe, 2.
The specific embodiment
1, fast and equably mixing concrete with added magnesium oxide flow process (with reference to Fig. 2).
2, evenly stir rapidly needing the outer magnesia that mixes in each mixed concrete, joining in required water of every mixed concrete and the additive, make the mixed liquor of magnesia and water and additive.
3, the concrete that joins in the mixer of the mixed liquor of magnesia that will evenly stir and water and additive mixes and stirs in the material, in conventional concrete mixing time, evenly mixes the concrete of making mixed magnesia.
4, be stirred among magnesia pulvis and the Yi Zaishui, but it is short stabilization time to stop stirring the back, easily precipitates.Stirring means adopts mechanical agitation or pneumatic stirring, and keeps normally open.
Implementation
Claim water, claim additive, claim magnesia, claim to finish, through water, additive, the magnesia of weighing, join in the stirred vessel jointly by mixing and stirring the material system electronic.
In stirred vessel, the water by mechanical agitation or pneumatic stirring, additive, magnesia, mixed liquor to mix and stir material at concrete be sand, stone, cement, feeding intake to mixer stirs before finishing.
The water, additive, the magnesian mixed liquor that evenly stir are joined the mixer inner concrete and mix and stir in the material, carry out the stirring of concrete with added magnesium oxide, its stir required time and conventional concrete time that stirs is similar.
Claims (3)
1. the method for a fast and equably mixing concrete with added magnesium oxide, comprise: claim that bucket aborts in (stirred vessel), magnesia siccative, additive, in water claims bucket (stirred vessel), make the magnesia mixed liquor earlier with mechanical agitation or pneumatic stirring to water, dropping into the mixer inner concrete again mixes and stirs in material, (sand, stone, cement), then mix the concrete of making mixed magnesia, it is characterized in that sending in the mixer is with mechanical agitation or the pneumatic magnesia mixed liquor that stirs; Mechanical agitation or pneumatic stirring keep normally open.
2. the method for a kind of fast and equably mixing concrete with added magnesium oxide according to claim 1 is characterized in that described magnesia mixed liquor is the mixed liquor of water, magnesia and additive.
3. the method for a kind of fast and equably mixing concrete with added magnesium oxide according to claim 1 is characterized in that described mechanical agitation or pneumatic stirring keep normally open, prevents that precipitation from taking place.
