Description
Technical field
The present invention relates to the brick field, exactly is the aerated bricks that a kind of raw material contains montmorillonite.
Background technology
The contaminative waste residue of discharging when red mud is Aluminium industry extraction aluminum oxide, 1 ton of aluminum oxide of the every production of average, 1.0～2.0 tons of red muds of subsidiary generation.China is as the world the 4th large alumina producing state, and the red mud of annual discharging is up to millions of tons.
Red mud mineralogical composition is complicated, adopt several different methods that it is analyzed, mainly contain following several method: seven kinds of methods such as polarizing microscope, flying-spot microscope, differential thermal analyzer, X diffraction, complete chemical analysis, infrared absorption spectrum and Mossbauer spectrometry are measured, consequently the essential mineral of red mud is aragonite and calcite, content is 60% ~ 65%, next is opal, gibbsite, pyrrhosiderite, and what content was minimum is titanium ore, spathic iron ore, urao, water glass, sodium aluminate and caustic soda.Its mineralogical composition is complicated, and does not meet the mineral assemblage of natural earth.In these ores, aragonite, calcite and spathic iron ore are skeleton, and certain cementation is arranged again; And pyrrhosiderite, gibbsite, opal, water glass play cementation and filling effect.
Gas concrete is a kind of novel wall material, and its unique distinction is that it is a kind of novel building walling of very light-duty heat insulating.Before the gas concrete technology starts from 100 years, and the relatively evening that this technology of China begins, than abroad totally having fallen behind 40 years, still, the development of the gas concrete industry of China is really very fast.Domestic gas concrete technical matters level can reach international most advanced level now.
The gas concrete sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, and the source of its raw material very extensively, dust and sand, slag, phosphorus ore slag and coal gangue etc. all are the starting material of doing gas concrete.And very superior of the performance characteristics of gas concrete, but extraordinary working ability and heat insulation and insulated capacity are arranged, and very strong of plasticity-, but Bao can saw, extraordinary processing characteristics is arranged.
According to authoritative sources statistics, several years ago there is family more than 300 in domestic gas concrete industry production enterprise.The throughput of each producer is also different, have produce per year 20,000 cubes also have the minority of producing 100000 cubes per year also to have to produce per year 300,000 cubes.And now slowly development of gas concrete industry heat is come, before being several times of present rough statistics, domestic gas concrete manufacturer quantity.
The application of gas concrete very extensively, mainly be used in the filling enclosure wall around the load-bearing walling such as materials for wall, infilled wall, floor and roof boarding in mechanical factory building and the covil construction and non-bearing material Hezhou.
Gradually, gas concrete has become the leading showpiece of building material industry, country now to clay solid brick forbid stop production.What replace gradually is exactly air-entrained concrete building block, autoclaved brick, however the intensity of the aerated bricks that general conventional gas concrete is made is lower.
