Abstract
A kind of superfine modified flyash production method.A certain amount of fly ash in electric power plant original powder is weighed first, is then added into the roller mill of a diameter of 500mm；Then activator is added, the mass ratio of activator and fly ash in electric power plant original powder is 3:10000, contain triethanolamine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon in the activator, the triethanolamine contained in the activator, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon mass ratio are 6：5：2：1：1：1：0.5；Superfine modified flyash can be obtained by being finally ground one hour.How spherical in shape the superfine modified fly ash grain of the method for the present invention production is regular and, and surface is smooth, large specific surface area, and activity is higher than ordinary fly ash.
Description
Technical field
The present invention relates to be related to flyash technical field more particularly to a kind of superfine modified flyash production method.
Background technology
Flyash is a kind of similar pozzolana mixed material that coal dust is formed after high-temp combustion.It is the hair of burning coal
Coal is worn into 100 microns of coal dusts below by power plant, and spray into burner hearth with preheated air burns at suspended state, and generation is contaminated with a large amount of
The high-temperature flue gas of incombustible has just obtained flyash through dust collect plant trapping.The chemical composition of flyash is similar to clayey, main
It is silica, alundum (Al2O3), di-iron trioxide, calcium oxide and uncompleted burned carbon to want ingredient.Currently, flyash is mainly used to mix
Material is closed in cement, concrete, but since its hydration rate is slow, early strength can be caused to be substantially reduced after mixing cement.
Invention content
The object of the present invention is to provide a kind of superfine modified flyash production method, the superfine modified flyash that it is produced
Regular particles and how spherical in shape, surface is smooth, large specific surface area, and activity is higher than ordinary fly ash.
In order to solve the problems existing in background technology, steps are as follows for the method for the present invention：
A certain amount of fly ash in electric power plant original powder is weighed first, is then added into the roller mill of a diameter of 500mm；
Then activator is added, the mass ratio of activator and fly ash in electric power plant original powder is 3:10000, in the activator
Containing triethanolamine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon, contain in the activator
Triethanolamine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon mass ratio be 6：5：2：1：1：
1：0.5；
Superfine modified flyash can be obtained by being finally ground one hour.
The superfine modified flyash that the method for the present invention is produced has the advantages that：
1. regular particles and how spherical in shape, surface is smooth, has good shape effect so that its water requirement is significantly less than
Ordinary fly ash.
2. superfined flyash particle is smaller, large specific surface area, activity is higher than ordinary fly ash.
3. having good form, can be applied to prepare the special properties concrete such as pumping, grouting, early strong.
Specific implementation mode：
The specific embodiment of the invention is as follows：
Embodiment 1：The present embodiment carries out as follows：
When production, fly ash in electric power plant original powder 5.0kg is first weighed, is then added into the roller mill of a diameter of 500mm,
Then the liquid activating agent of 1.5g, grinding one hour are added in being ground again to roller, you can obtain superfine modified flyash, the activation
Containing triethanolamine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon in agent, in the activator
Triethanolamine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, the calgon mass ratio contained is 6：5：2：
1：1：1：0.5.
Through experiment, superfine modified flyash 135g, cement 315g, normal sand 1350g, water 225ml are weighed, agitated kettle is put into
In, after cement mortar mixer automatic stirring, it is added in three joint-trials mill and is molded, maintenance is demoulded after 24 hours and discharged water
Middle maintenance breaks type after 3 days, 7 days, 28 days.
In addition the II grade of ash of power plant's selection by winnowing, power plant's former ash grinding ash, standard cement for weighing equal quality respectively again carry out together
The experiment of sample, referring finally to GB/T1596-2005《For the flyash in cement and concrete》Compare surface area, 3 days, 7 days,
The parameters such as anti-folding/resistance to compression in 28 days, activity intensity ratio are detected, and specific data see the table below：
How spherical in shape the superfine modified fly ash grain that the method for the present invention is produced is regular and, and surface is smooth, has good
Shape effect so that its water requirement is significantly less than ordinary fly ash, and superfined flyash particle is smaller, large specific surface area, live
Property be higher than ordinary fly ash, there is good form, can be applied to prepare pumping, grouting, the early special properties concrete such as strong.
