Description
Technical field
The present invention relates to building material field, be specifically related to a kind of unburned attapulgite flyash haydite insulating brick.
Background technology
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, makes Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area are caused to serious threat.
Attapulgite clay, except containing attapulgite, often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
The volcanoclastic rock that also has with the symbiosis of attapulgite clay ore deposit, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the thickness of the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area is up to tens of rice, attapulgite clay is in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, according to field trip, the volcanoclastic rock that 1 ton of attapulgite clay of every exploitation produces has more than 30 tons, calculate by the output of producing 150000 tons per year, the volcanoclastic rock producing is up to 4,500,000 tons, all can be utilized for many years, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, cause the serious wasting of resources and financial loss.
Flyash is to receive and catch the thin ash getting off in the flue gas from coal combustion, the main solid waste that flyash Ye Shi coal-burning power plant discharges, be one of industrial residue that the current discharge capacity of China is larger, along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; Can cause river to silt up if enter water system, toxic chemical substance wherein also can work the mischief to human body and biology.
Haydite is a kind of artificial lightweight coarse aggregate, and case surface is coarse and hard, and inner porous is generally formed through pulverizing, granulation, sintering and screening by the material such as shale, clay rock.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of unburned attapulgite flyash haydite insulating brick is provided.
The batching of unburned attapulgite flyash haydite insulating brick is by attapulgite clay mine tailing, spherical attapulgite lytag, volcanoclastic rock mixture, wilkinite mine tailing, diatomite mine tailing and cement composition; The batching process of unburned attapulgite flyash haydite insulating brick is stirred, be pressed into difform unburned attapulgite flyash haydite insulating brick work in-process, maintenance is carried out in conventional maintenance process according to cement products, is packaged as the finished product of unburned attapulgite flyash haydite insulating brick after 28 days.
Attapulgite clay be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral, attapulgite clay soil property exquisiteness, water-absorbent is strong, tool viscosity and plasticity-when wet, be conducive to the bonding between raw material, and can improve intensity and the porosity of unburned attapulgite flyash haydite insulating brick.
Attapulgite clay can mix in recovery process a certain amount of rubble and earth, cannot sieve, and abandons as a kind of mine tailing, causes a large amount of wastings of resources, and the present invention selects the attapulgite clay mine tailing after pulverizing, particle fineness≤0.149 millimeter.
Spherical attapulgite lytag is spheroidal, epidermis is coarse and hard, there is a large amount of trickle pores inside, that one is lightweight, intensity is high, thermal conductivity is low, refractoriness is high, chemical stability is good, weather resistance and the good building porcelain granule of heat preservation and soundproof performance, and the present invention selects particle diameter≤20.0 millimeter of spherical attapulgite lytag.
Volcanoclastic rock is the rock of the transitional type between magma lava and sedimentogeneous rock, the material that wherein more than 50% composition is sprayed by pyroclastic flow forms, and these tephras are mainly the lava of premature coagulation on volcano, the rock formation that passage is around burst in the time of volcanic eruption.Volcanoclastic rock mixture comprises landwaste, brilliant bits, glassiness bits, slurry bits, volcanic block, volcanic gravel and volcanic ash, volcanoclastic rock can increase the intensity of unburned attapulgite flyash haydite insulating brick, the present invention selects the volcanoclastic rock mixture after pulverizing, particle fineness≤5.0 millimeter.
Wilkinite has plasticity-and agglutinating value(of coal), and the wilkinite mine tailing that the present invention selects is distributed in the lower floor in attapulgite clay ore deposit mostly, is difficult to carry out independent exploitation, quality is also poor, major part is abandoned in mine tailing district, and the present invention selects the wilkinite mine tailing after pulverizing, particle fineness≤0.25 millimeter.
Diatomite exquisiteness, loose, light weight, porous, specific surface area is large, space is regular distribution, stable chemical nature, it is a kind of natural nano aperture amorphous silicon material, but diatomite is made a low multiple use, most products come from one-level soil, and two, three grades of soil are discarded in a large number, caused serious waste of resources, also polluted environment, diatomite can increase the porosity of unburned attapulgite flyash haydite insulating brick, the present invention selects the diatomite mine tailing after pulverizing, particle fineness≤0.25 millimeter.
Cement selection silicate cement.
