Description
Technical field
The present invention relates to field of Environment Protection, in particular it relates to be manufactured using special soil body stabilizing agent recycling treatment iron tailings
It is non-burning brick.
Background technology
Ore resource is valuable cargo for the survival of mankind, the exploitation of ore embody a technology for country and
Economic strength.Ore resource is non-renewable resources, and the grade of technique of preparing and ore limits making full use of for ore resource.
Mill tailings is under certain technical conditions, the solid waste produced after useful component to be chosen from finished ore.
Iron tailings be iron ore by it is levigate, sort the industrial solid castoff for producing afterwards.At present, the iron tailings of China
Comprehensive utilization ratio only has 7%, and volume of cargo in storage has more than ten00000000 tons, accounts for nearly 1/3rd of whole tailings impoundment total amounts.Therefore, iron tail
The comprehensive reutilization problem of ore deposit has got more and more people's extensive concerning.
With the cry more and more higher of countries in the world energy-saving and emission-reduction, because unburned product have low production cost, process is simple,
The features such as environmental protection, is produced and is applied extensively.Fired brick complex steps in preparation process, not only consume a large amount of soils,
And consume a large amount of heat energy, discharge substantial amounts of CO2, do not meet the policy of China's " energy-saving and emission-reduction ".Make unburned using iron tailings
Brick can be with recycling iron tailings.
The content of the invention
In order to solve the above problems, special soil body stabilizing agent recycling treatment iron tailings system is used the invention provides one kind
That makes is non-burning brick, and the non-burning brick material for preparing includes iron tailings, the cement of 3-10 weight portions, the 8-10 of 90-97 weight portions
The water of weight portion and the soil body stabilizing agent of 0.01-0.1 weight portions, the soil body stabilizing agent by 100 weight portions water, 1-15 weight
Measure the surfactant of part, boric acid or the borate composition of 0.1-10 weight portions.
The cement is 425# Portland cements.
The pH value of the soil body stabilizing agent is adjusted to 8-11.
The surfactant is selected from glycerin monostearate, dioctyl succinate disulfonate acid, stearate, alkyl ether carboxylic
In hydrochlorate, butyl naphthalene sulfonate one or more.
The non-burning brick sulfuric acid for preparing Ludox and 0.01-0.1 weight portion of the material also including 0.5-3 weight portions
Sodium.
A kind of non-burning brick preparation method, comprises the following steps：
The cement of 3-10 weight portions, the water of 8-10 weight portions are mixed with the iron tailings of 90-97 weight portions in the first blending bunker
3-15 minutes, obtain cement iron tailings batch mixing；
The soil body stabilizing agent of cement iron tailings batch mixing, the Ludox of 0.5-3 weight portions and the 0.01-0.1 weight portions that will obtain exists
After mixing 3-15 minutes in second blending bunker, the sodium sulphate mixing of 0.01-0.1 weight portions 3-5 minutes is added, obtain non-burning brick mixed
Close material；
Compressing, natural curing under non-burning brick compound normal temperature is obtained into non-burning brick finished product.
Surfactant of the invention can be adsorbed in the surface of bulky grain, change the hydrophily of particle surface so that
Grain has the effect of shield water, reduces the water imbibition of particle, and what is prepared is non-burning brick with good permeability resistance, and then has
There is good compression strength.The surfactant of present invention selection has alkyl segment more long, and alkyl segment has fabulous
Pliability and repellency, can more efficiently improve the repellency of particle surface.Present invention employs a small amount of cement, add
Boric acid or borate, substantially increase non-burning brick compression strength, employ soil body stabilizing agent of the invention, can be in large quantities
Reduce the usage amount of the cement compression strength non-burning brick without reducing shaping.
The water of 8-10 weight portions of the present invention can be that additional water, or additional water and iron tailings contain
The summation of water.Press strengthi of the invention is 20Mpa.The iron tailings relatively low for silicone content, the non-burning brick mechanical strength of acquisition
It is relatively low, present invention adds Ludox and sodium sulphate, sodium sulphate as Ludox activator, Ludox formed in mineral surface
And be crosslinked, worked in coordination with the boric acid in soil body stabilizing agent, the degree of cross linking between non-burning brick middle particle is improve, substantially increase
Non-burning brick mechanical strength.
Iron tailings as aggregate standard brick need to largely be mixed cement by conventional method, be had to pass through after shaping " steam-cured "
Can be only achieved strength criterion.The energy is not only largely consumed, environment is polluted, also a large amount of consumption Resources（Cement）, single brick into
This height.The present invention uses special soil body stabilizing agent, only with iron tailings as non-burning brick material of main part, preparation it is unburned
Brick has good compression strength and water resistance.
The above-mentioned of the application and other features, aspect and advantage is more readily understood with reference to described further below.
