Description
Technical field
The present invention relates to building material field, be specifically related to the sintered porous building block of a kind of Attapulgite shale powder flyash haydite.
Background technology
Novel wall material mainly refers to the material of construction take non-clay resources such as sandstone, shale, industrial solid waste residue, the remaining soil of building as the starting material mechanization production; have protection soil, protection of the environment, save energy, utilize refuse, gain in strength and the characteristic such as economic and practical; shale building block is compared with clay solid brick; sharpest edges are that its production does not damage the arable land and energy consumption is lower, meet national technical development policy.
Shale is to be pushed in earth movement and the rock that forms by clay, have laminated or laminar bedding, impact easy splinter with hard thing, shale does not have viscosity, and plasticity-and water-permeable are all very poor, block shale need to be pulverized and just can be processed into shale building block after very thin, otherwise dried shale building block crackle is many, and can produce explosion in sintering process, fraction defective is higher, has increased production cost.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among the 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, even violation operation, make Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area caused serious threat.
Attapulgite clay often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate except containing attapulgite.
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 the upper strata, attapulgite clay mining area that has 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, investigate factually, 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 that produces is up to 4,500,000 tons, all can not obtain for many years utilizing, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, causes the serious wasting of resources and financial loss.
Flyash is to receive the thin ash of catching the flue gas behind coal combustion, flyash also is the main solid waste that the coal-burning power plant discharges, be one of larger industrial residue of the current discharge capacity of China, 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 the river to silt up if enter water system, toxic chemical substance wherein also can work the mischief to human body and biology.
