Description
Technical field
The present invention relates to a kind of method using granulated blast-furnace slag preparation superelevation strong rubber gel material, especially a kind of utilizations
The method that superelevation strong rubber gel material is made in granulated blast-furnace slag by superfine grinding method belongs to metallurgy, utilization of resources environmental protection and section
It can emission reduction field.
Background technique
China is big steel country, and pig iron yield in 2013 is 708,970,000 tons, and slag yield is 241,050,000 tons, utilization rate
It is 82%, main utilization ways are production ground granulated blast furnace slag and cement admixture, and still having more than 40,000,000 tons cannot get benefit
With.
The processing mode of granulated blast-furnace slag is chilling water quenching, and ground granulated blast furnace slag is made in grinding.GB/T18046-
2008《For the ground granulated blast furnace slag in cement and concrete》Ground granulated blast furnace slag is divided into S105, S95, S75 tri-
Grade.The granulated blast-furnace slag activity of part ground-slag manufacturing enterprise reflection at present reduces, difficulty up to standard.
The vitreum mass content of granulated blast-furnace slag is higher, and potential activity is bigger.Influence granulated blast-furnace slag activity
Principal element have vitreum mass content and ground-slag specific surface area.Determine the main of granulated blast-furnace slag vitreum mass content
Temperature and cooling velocity (i.e. slag water ratio) when factor is slag chilling.The way of contact in grinding duration and grinding process then determines
The fineness of ground granulated blast furnace slag.
Raw material, which reaches after vitreum mass content requires, carries out grinding.The particle of ground granulated blast furnace slag is thinner, specific surface
Product is bigger, and reaction contact area is bigger in hydration process, can effectively improve reaction speed.Material is impacted, sheared, rubbed applying
After the mechanical forces such as wiping, compression, extension, internal crystal structure meeting randomization and generation multiphase crystal transfer lead to crystalline substance
Lattice defect occurs, specific surface area increases, surface can increase, therewith the macroscopic property, crystallographic properties of material, physical chemistry
Property etc. all can Development pattern variation.With the increase of grinding duration, since reuniting effect may be such that grain graininess no longer subtracts
It is small, but continue grinding and still can produce new activation point, while internal generation defect and crackle, make ground-slag in alkaline aqueous solution
In be easy to evenly dispersed, be conducive to OH-Ion enters granulated blast-furnace slag and hydration reaction occurs.Additionally by grinding material
Grinding aid is added, reuniting effect can be destroyed to a certain degree, continue growing fineness.
Summary of the invention
In the present invention, a large amount of vitreums are contained in granulated blast-furnace slag, there is certain hydration activity, be a kind of gelling material
Expect resource.Granulated blast-furnace slag of the vitreum mass content not less than 95% is chosen in the present invention as preparation superelevation strong rubber coagulates material
The raw material of material.
The grinding aid of selection is the mixture of triethanolamine and flyash.By triethanolamine and flyash with mass ratio for 1:

(2) discharge specific surface area：≥800m2/kg。
According to the ground-slag of different product requirement production different fineness：Specific surface area is in 800-1200m2The granulation of/kg is high
Furnace Slag super-fine powder is used as production superelevation strong rubber gel material；Specific surface area is greater than 1200m2The granulated blast-furnace slag Ultramicro-powder of/kg
For replacing silicon ash.
It is an advantage of the invention that grinding aid is added on the basis of controlling base glass weight content carries out grinding, it can
To obtain granulated blast-furnace slag superfine powder product under conditions of low energy consumption, low cost.It can be with method of the present invention
Make whole granulated blast-furnace slags obtain high attached value resourceization to utilize, realizes that granulated blast-furnace slag processing is maximum using industry interests
Change.
A kind of process flow of method using granulated blast-furnace slag preparation superelevation strong rubber gel material is：Tap cinder → height
Pressure water quenching → grain slag is dehydrated → admixes grinding aid → connected superfine pulverizer grinding to specific surface area and reaches 800m2/ kg or more → feed bin
→ ground-slag resource utilization.
