The present invention relates to a method of manufacturing brick construction waste.
BACKGROUND
Now, with China's economic development, gradually narrowing the gap between urban and rural areas, the city is not in the transformation
Constantly modernized, towns in the building constantly urbanization. Widely applied traditional brick around a lot
Production both on the relative absence of the arable land has posed a grave threat, but also consumes a lot of energy
Source, demolition and renovation of the old city and the urban and rural New construction of large quantities of construction waste landfill and dumping,
Not only pollutes the environment, but also a waste of resources. Chinese patent "unburned steamed building bricks" (Patent No.
03112260.4) provides a wide range of sources of raw materials, low-cost steamed unburned brick building,
"It's the main ingredient and excipients as a gelling agent composition" "Ingredients used as gravel or slag, the use of plastic
Coagulant board yellow powder and quicklime ";" yellow board high content of calcium oxide powder, can put the
Class gravel or slag sticking together tightly by pressure forming, The Nature Conservancy to form hydrated silicate
Salts of calcium, reduced to Tomo mullite crystals. "As used in these products much construction waste, so the solution
Decisions urban construction waste little help; Ingredients used mostly slag, fly ash, coal gangue, which affected workers
Industry on geographical restrictions, production of the invention, the limitations of brick construction; Also in the production process to
The molding pressure, which increases the equipment, resulting in a complex production process and increased investment.
