Abstract
A kind of superfine modified flyash.It is formed by flyash original powder and activator combined grinding, the mass ratio of the flyash original powder and activator is 10000:3, 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.Regular particles of the present invention and how spherical in shape, surface is smooth, large specific surface area, and activity is higher than ordinary fly ash.
Description
Technical field
The present invention relates to flyash technical field more particularly to a kind of superfine modified flyash.
Background technique
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, is sprayed into burner hearth with preheated air and is burnt at suspended state, 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
Wanting ingredient is silica, aluminum oxide, di-iron trioxide, calcium oxide and uncompleted burned carbon.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.
Summary of the invention
The object of the present invention is to provide a kind of superfine modified flyash, its regular particles and how spherical in shape, surface is smooth, than
Surface area is big, and activity is higher than ordinary fly ash.
In order to solve the problems existing in background technology, technical solution of the present invention are as follows: it is by flyash original powder and activator
Combined grinding forms, and the mass ratio of the flyash original powder and activator is 10000:3, contains three ethyl alcohol in the activator
Amine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon, three ethyl alcohol contained in the activator
Amine, ethylene glycol, sodium metasilicate, sodium sulfite, glycerine, stearic acid, calgon mass ratio are 6:5:2:1:1:1:0.5.
The superfine modified flyash of the present invention 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 embodiment
The specific embodiment of the invention is as follows:
Embodiment 1: the present embodiment carries out as follows:
It is formed the superfine modified flyash of the present invention by flyash original powder and activator combined grinding, the flyash original powder
Mass ratio with activator is 10000:3, contains triethanolamine, ethylene glycol, sodium metasilicate, sodium sulfite, third in the activator
Triol, stearic acid, calgon, the triethanolamine contained in the activator, ethylene glycol, sodium metasilicate, sodium sulfite, the third three
Alcohol, stearic acid, calgon mass ratio are 6:5:2:1:1:1:0.5.
When production, fly ash in electric power plant original powder 5.0kg is first weighed, is then added into the roller mill that diameter is 500mm,
Then the liquid activating agent of 1.5g is added into roller mill again, grinding one hour, superfine modified flyash can be obtained.
It is tested, weighs superfine modified flyash 135g, cement 315g, normal sand 1350g, water 225ml, be put into agitated kettle
In, after cement mortar mixer automatic stirring, it is added in three joint-trials mill and forms, 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 test of sample, referring finally to GB/T1596-2005 " for the flyash in cement and concrete " comparison 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 of the present invention is regular and, and surface is smooth, has good shape effect, makes
It obtains its water requirement and is significantly less than ordinary fly ash, superfined flyash particle is smaller, large specific surface area, and activity is higher than common fine coal
Ash has good form, can be applied to prepare the special properties concrete such as pumping, grouting, early strong.
