The invention relates to a rapid high-strength hardener composition for a pelitization substance of mudstone of a laneway base plate of a mine and a method for preparing the same. The composition is prepared through mixing and grinding sulphate aluminium cement clinker, hydrated gypsum, hydrated lime, sodium sulfate, sodium silicate, aluminum potassium sulfate and sodium hydroxide into powder with specific surface area of between 200m<2>/kg and 900m<2>/kg. The rapid high-strength hardener composition carries out reinforcing treatment on the pelitization substance of mudstone and has the advantages of short time for forming a condensate and high strength of the formed condensate.
Description
Technical field
The present invention relates to a kind of curing agent composition and preparation method thereof, more specifically, the present invention relates to a kind of quick high-strength curing agent composition that is specifically designed to mine working base plate mud stone argillization thing and preparation method thereof.
Background technology
The mine working floor strata is many to be made up of mud stone or mud shale, and mud stone can form the mud stone argillization thing of similar mud under certain condition after meeting water, thereby the phenomenon of softening disintegration occurs, and this makes the mine working base plate become muddy.Passing through of the muddy serious obstruction equipment of roadway floor meeting, vehicle influences the construction and the operating environment in tunnel, tunnelling speed also had a significant impact, thereby cause serious economy loss.
For addressing the above problem, for the processing of described mud stone argillization thing, normally abandon in the stockyard after the desilting of described mud stone argillization thing it being transported the tunnel, in the tunnel, build certain thickness concrete road surface then.Treatment process although it is so can solve the problem that above-mentioned roadway floor becomes muddy, but because concrete needs some days curing time, therefore the tunnel can not traffick and equipment in preserving period, thereby influence the tunneling construction speed in whole tunnel, and described mud stone argillization thing is abandoned in a large number in the stockyard and can be caused serious pollution to the mining area surrounding enviroment.
In addition, for addressing the above problem, industry also adopts another method that described mud stone argillization thing is handled, and promptly uses reinforcement material that described mud stone argillization thing is carried out consolidation process.In this treatment process, employed reinforcement material mainly is cement and lime.Yet the mud more general owing to the microtexture of mud stone argillization thing is more loose, and is being mingled with the bigger cinder of particle diameter and soft rock chip and organic substance, makes the physical property of mud stone argillization thing be different from general mud.Because it is longer that cement and described mud stone argillization thing form the time of cured body, and the intensity of the final cured body that forms is on the low side, therefore uses the effect of the described mud stone argillization of cement stabilization thing unsatisfactory usually.When described mud stone argillization water content of matter was higher, lime was not good enough for its consolidation effect yet, can exist to be reinforced the shortcoming that thing intensity is lower and lime consumption is bigger than normal.
Therefore, the object of the present invention is to provide a kind of quick high-strength curing agent composition that is specifically designed to mine working base plate mud stone argillization thing, to solve the above-mentioned problems in the prior art, thereby can not influence the tunneling construction speed in whole tunnel, and it is not polluted the mining area surrounding enviroment owing to the existence of mine laneway base plate mud stone argillization thing.
Summary of the invention
The object of the present invention is to provide a kind of quick high-strength curing agent composition that is specifically designed to mine working base plate mud stone argillization thing.
Another object of the present invention is to provide a kind of preparation method of above-mentioned composition.
The quick high-strength curing agent composition that is used for mine working base plate mud stone argillization thing provided by the present invention, by weight percentage, said composition is made up of following component:
