Abstract
The invention discloses a production method of superfine modified coal ash.The production method includes: weighing a certain amount of power plant coal ash raw powder, and adding the power plant coal ash raw powder into a drum mill of 500 mm in diameter; adding an activating agent, wherein a mass ratio of the activating agent to the power plant coal ash raw powder is 3:10000, and the activating agent contains triethanolamine, ethylene glycol, sodium silicate, sodium sulfite, glycerol, stearic acid and sodium hexametaphosphate according to a mass ratio of 6:5:2:1:1:1:0.5; grinding for one hour to obtain the superfine modified coal ash.The superfine modified coal ash produced by the method has regular particles and is mostly spherical, smooth in surface, large in specific surface area and higher than common coal ash in activity.
Description
Technical field
The present invention relates to and relate to flyash technical field, particularly relate to a kind of superfine modified flyash production method.
Background technology
Flyash is the similar pozzolana mixed material of one that coal dust is formed after high-temp combustion.It is that coal is worn into the coal dust of less than 100 microns by the power plant of burning coal, sprays into burner hearth with preheated air and becomes suspended state burn, and generation is contaminated with the high-temperature flue gas of a large amount of incombustible, traps through dust collect plant and just obtains flyash.The chemical composition of flyash is similar to clayey, is mainly composed of silicon dioxide, aluminium sesquioxide, iron sesquioxide, calcium oxide and uncompleted burned carbon.At present, flyash is mainly used to admixture in cement, concrete, but owing to its hydration rate is slow, early strength can be caused after mixing cement substantially to reduce.
Summary of the invention
It is an object of the invention to provide a kind of superfine modified flyash production method, how spherical in shape the superfine modified fly ash grain that it is produced is regular and, smooth surface, and specific surface area is big, and its activity is higher than ordinary fly ash.
In order to solve the problem existing for background technology, the inventive method step is as follows:
First weigh the former powder of a certain amount of fly ash in electric power plant, be then added in the cylinder mill that diameter is 500mm；
Then activator is added, the mass ratio of activator and the former powder of fly ash in electric power plant is 3:10000, containing triethanolamine, ethylene glycol, sodium silicate, sodium sulfite, glycerol, stearic acid, sodium hexameta phosphate in described activator, the triethanolamine contained in described activator, ethylene glycol, sodium silicate, sodium sulfite, glycerol, stearic acid, sodium hexameta phosphate mass ratio are 6:5:2:1:1:1:0.5；
Finally it is ground one hour obtaining superfine modified flyash.
The superfine modified flyash that the inventive method is produced has the advantages that
1. regular particles and how spherical in shape, smooth surface, there is good shape effect so that its water requirement is significantly less than ordinary fly ash.
2. superfined flyash granule is less, and specific surface area is big, and its activity is higher than ordinary fly ash.
3. there is good form, can be applicable to preparation pumping, grouting, early the special property concrete such as strong.
Detailed description of the invention:
The specific embodiment of the invention is as follows:
Embodiment 1: the present embodiment carries out as follows:
During production, first weigh the former powder 5.0kg of fly ash in electric power plant, it is then added in the cylinder mill that diameter is 500mm, then the liquid activating agent of 1.5g is added to cylinder in grinding again, grinding one hour, superfine modified flyash, containing triethanolamine, ethylene glycol, sodium silicate, sodium sulfite, glycerol, stearic acid, sodium hexameta phosphate in described activator, the triethanolamine contained in described activator, ethylene glycol, sodium silicate, sodium sulfite, glycerol, stearic acid, sodium hexameta phosphate mass ratio are 6:5:2:1:1:1:0.5.
Through test, weigh superfine modified flyash 135g, cement 315g, normal sand 1350g, water 225ml, put in agitated kettle, after being terminated by cement mortar mixer automatic stirring, adding molding in three joint-trials mills, after maintenance 24 hours, the demoulding discharges water broken type after middle maintenance 3 days, 7 days, 28 days.
Additionally weigh II grade of ash of power plant's selecting crude drugs with winnower of equal quality, power plant former ash grinding ash more respectively, standard cement carries out same test, referring finally to GB/T1596-2005 " flyash in cement and concrete " contrast table area, 3 days, 7 days, 28 days anti-folding/resistance to compression, the parameter such as activity intensity ratio detect, concrete data are shown in following table:
How spherical in shape the superfine modified fly ash grain that the inventive method is produced is regular and, smooth surface, there is good shape effect, its water requirement is made to be significantly less than ordinary fly ash, superfined flyash granule is less, and specific surface area is big, and its activity is higher than ordinary fly ash, there is good form, can be applicable to preparation pumping, grouting, early the special property concrete such as strong.
Claims (1)
1. a superfine modified flyash production method, the steps include:
