Abstract
The invention discloses a baking-free brick prepared from red mud. Bayer process red mud is high in alkali content, and the problem of efflorescence can be easily caused during the production of a building material. A geopolymer synthesis technology is used for converting alkali in the red mud into an activator in an activation way, so that problems caused by the alkali during the utilization of the red mud are solved. The baking-free brick is mainly prepared from the following raw materials in parts by weight: 3 to 8 parts of water glass, 15 to 20 parts of active initiator, 70 to 80 parts of red mud and 0.5 to 1 part of micro silicon powder. The baking-free brick is prepared by the following steps of sequentially adding the red mud, the active initiator, the water glass and the micro silicon powder into a forced mixer, performing extrusion forming by using a brick making machine after uniform mixing, standing a brick blank for 1 to 2 hours under natural conditions to endow certain hardness to the brick blank, feeding the brick blank to an autoclave, and performing autoclaved curing for 2 to 4 hours under pressure of 0.8 to 1.2MPa to obtain a finished product. The baking-free brick prepared from red mud is low in cost, stable in product performance, strong in compressive strength and high in freezing and thawing cycle resistance, a production process is simple, the production site is small, and efflorescence after building is avoided.
Description
Technical field
The present invention relates to a kind of non-burning brickly, especially a kind of prepare with red mud non-burning brick, belongs to building material technical field.
Background technology
The contaminative waste residue of discharging when red mud is Aluminium industry extraction aluminum oxide.Red mud complicated component, contains a large amount of fluorochemicals and alkaline matter, if let alone random stacking, can cause severe contamination to environment, and the annual red mud quantity discharged of China is up to up to ten million ton, a large amount of red muds on producing, life caused many-sided impact.At present the processing mode of red mud is mainly contained to production cement, manufacture walling unit, manufacture lightweight aggregate concrete and as road foundation material etc.But because China's red mud content is large, water ratio is high, alkalescence is strong, causes the utilization ratio of red mud lowly, or is limited to use.Therefore, how to process better red mud be highly significant in research.
Summary of the invention
It is high that technical problem to be solved by this invention is to provide a kind of crushing resistance, the red mud brick of the accumulation of salt in the surface soil not after building by laying bricks or stones.
The solution of above-mentioned technical problem is to have adopted following technical measures: a kind of prepare with red mud non-burning brick, mainly by the raw material of following weight parts, prepared:
The active material 15-20 red mud 70-80 SILICA FUME 0.5-1 that causes of water glass 3-8;
Described water glass is modulus 1.5-2.5, the one or any ratio mixture in the commercially available industrial sodium silicate of degree Beaume 40 or potash water glass;
Described activity causes material for fineness 100-400 object blast furnace granulated slag, 100-400 object bessemer furnace slag, 100-400 order and under 750 ℃ of constant temperatures, calcines coal gangue, the 100-400 order of 2 hours and under 750 ℃ of constant temperatures, calcine the one or any ratio mixture in the Kaolin Tailings of 2 hours;
Described red mud is the red mud that water-content 30% use Bayer process is produced.
Above-mentioned raw materials, by following method, prepared:
(1) proportionally take various raw materials;
(2) various raw materials are joined in stirrer one after another according to red mud, the active order that causes material, water glass, SILICA FUME, stir, through brick machine, be squeezed into adobe;
(3) by adobe under field conditions (factors) standing 1-2 hour after adobe produces certain degree of hardness, send into steam pressure reactor, under 0.8-1.2MPa pressure, maintenance 2-4 hour, gets product.
Take the present invention of above-mentioned measure, in red mud, added the blast furnace granulated slag, bessemer furnace slag, coal gangue and the Kaolin Tailings isoreactivity that contain aluminosilicate to cause material and water glass and SILICA FUME.For the high feature of red mud sodium ions content, use ground polymers synthetic technology, sodium ion in red mud is changed into a part for exciting agent in ground polymers building-up process, using other compositions of red mud as exciting object, make added raw material generation depolymerization-polycondensation, form a kind of inorganic polymer material of excellent property.Above-mentioned raw materials, through extruding brick press extruding, is prepared into base material, after high-temperature high-pressure reaction kettle, be prepared into ultimate compression strength can reach MU20, freeze-thawing resistant, build by laying bricks or stones after the not accumulation of salt in the surface soil, the fixing walling unit of sodium ion.The present invention is without sintering thereby can reduce energy consumption, reduces and pollutes, and has improved production efficiency, and has used red mud in a large number, overcomes brick complex manufacturing prepared by same type of material, the deficiency that red mud consumption is low.
