Description

For colliery wastes brick and the production method thereof of load larrying member body of wall
Technical field
The present invention relates to building material field, a kind of intensity is greatly for colliery wastes brick and the production method thereof of load larrying member body of wall specifically.
Background technology
The main component of colliery wastes brick is coal gangue.Coal gangue is the rock that common consedimental organic compound and mineral compound mix with coal in coalification course, usually in thin layer and in coal seam or top, coal seam, at the bottom of coal seam, being that mine that the quantity that produces in construction of coal mine and coal digging, dressing of coal by washing process is larger is solid-state dumps thing.Its main component is Al 2o 3, SiO 2, also contain the Fe that quantity does not wait in addition 2o 3, CaO, MgO, Na 2o, K 2o, P 2o 5, SO 3with micro-rare elements (gallium, vanadium, titanium, cobalt).Coal gangue is divided into clay rock class, sandstone rock class, carbonate, pelite class by essential mineral content; By sources and final state, coal gangue can be divided into digging gangue, coal separation spoil and natural spoil three major types.Coal gangue quantity discharged has larger difference according to the difference of coal seam conditions, field conditions and washing process, and general digging gangue accounts for about 10% of raw coal output, and coal separation spoil accounts for 12% ~ 18% of feed coal amount.
Comparatively common brick is low for the production cost of colliery wastes brick, and the more common clay brick of intensity of colliery wastes brick is high, utilizes making coal gangue brick not only to save soil, also consumes the waste material in mine, and it is an environmentally friendly low-carbon (LC) material of construction.Along with deepening constantly of policies of reform and opening to the outside world, the development of market economy, urban construction develop rapidly, all kinds of public works, public utility, Highrise buildings, covil construction, Comfortable Housing Project is rised sheer from level ground, a large amount of novel wall material will be needed, colliery wastes brick is main new materials for wall, although the intensity of colliery wastes brick is about common clay brick twice, but in the urban construction of reality, some building is more and more higher to the requirement of bearing wall intensity, therefore, the intensity of common colliery wastes brick can not practical requirement, research need be made to this, the intensity of further increase colliery wastes brick.
Summary of the invention
The object of the present invention is to provide the colliery wastes brick for load larrying member body of wall and production method thereof, to solve the problem that above-mentioned common colliery wastes brick intensity can not meet working strength.
For achieving the above object, basic technology scheme of the present invention is to provide the colliery wastes brick for load larrying member body of wall, is made up of the raw material of following weight part:
Coal gangue 60-65 part, cement 9-10 part, glue 0.3-0.5 part, clay 5-8 part, wilkinite 2-4 part, boron mud 4-6 part, toughener 5-6.5 part, leaf sheath fibres of Fortune Windmillpalm 3-4 part, aluminium hydroxide 2-3 part, sodium carbonate 1-2 part, blast furnace slag 3-5 part, water are appropriate;

Better, the proportioning raw materials of toughener is specially: bamboo charcoal 7 parts, Starso 1 part, stearic acid 0.3 part, magnesium-aluminium spinel 35 parts, silicon sol 7 parts, 0.9 part, nitrocellulose, 12 parts, boccaro ore deposit soil, water is appropriate.Making step is identical with above-mentioned steps.
Colliery wastes brick for load larrying member body of wall of the present invention, be made up of following concrete steps:
1) coal gangue is delivered to Raw material processing factory building, pulverizes through pulverizer, then utilize trommel screen or vibratory screening apparatus screening, obtain Powdered qualified material, by palm leather end;
2) then clay, blast furnace slag, wilkinite, boron mud, sodium carbonate, coal gangue, leaf sheath fibres of Fortune Windmillpalm and aluminium hydroxide are mixed, continue evenly to stir 30-40 minute;
3) again the mixture of cement, glue, toughener and second step gained is mixed, while mixing, add suitable quantity of water and be stirred to formation paste, continue again after forming paste to stir 20-30 minute, then by aging bunker ageing;
4) make adobe after the mixture of third step gained being stirred 30-40 minute again, typically use vacuum brick making machine and make adobe;
5) again drying shed is sent in adobe to dry, then the adobe of oven dry delivered in kiln and sinter, first preheating, then high temperature sintering during sintering, then low temperature ending, obtains finished product colliery wastes brick of the present invention.
Beneficial effect of the present invention is: the present invention fills a prescription rationally, mixes as brick producing material, make full use of coal gangue refuse, reach the object of energy-saving and emission-reduction with boron mud etc.; By the mixing of cement, glue, colliery wastes brick toughness and intensity are strengthened, the toughener agent that interpolation special process and material are made, adds blast furnace slag as raw material, further enhancing the ultimate compression strength of colliery wastes brick, colliery wastes brick bearing capacity is promoted greatly; Repeatedly mix when the present invention makes, stir very even, be beneficial to the performance promoting colliery wastes brick, avoid occurring crack phenomenon; The present invention simultaneously, under the rational proportion of various material, has the effect such as good water permeability, lightweight, is applicable to promoting the use of.
Embodiment
Below by embodiment, the present invention is further detailed explanation.
Embodiment, the colliery wastes brick for load larrying member body of wall is made up of the raw material of following weight part: coal gangue 63 parts, cement 9.5 parts, glue 0.4 part, clay 7 parts, wilkinite 3 parts, 4.5 parts, boron mud, toughener 6 parts, leaf sheath fibres of Fortune Windmillpalm 3.4 parts, 2 parts, aluminium hydroxide, 1.5 parts, sodium carbonate, blast furnace slag 4 parts, water are appropriate.Wherein the proportioning raw materials of toughener is: bamboo charcoal 7 parts, Starso 1 part, stearic acid 0.3 part, magnesium-aluminium spinel 35 parts, silicon sol 7 parts, 0.9 part, nitrocellulose, 12 parts, boccaro ore deposit soil, water is appropriate.
