Historic grey bricks burned by river mud and production method thereof

Abstract

The invention relates to historic grey bricks burned by river mud and a production method thereof. The historic grey brick comprises the following components by mass percentage: 30-50% of mud, 40-60% of shale, 5-10% of waste ceramsite, and 0.2-0.6% of a defrosting agent. The historic grey brick employs mud and shale for mixing, and solves the problems of shortage of the raw materials and high exploitation / transport cost in the prior art, land resources are protected, and the method provides a processing approach for solid waste mud generated by river mud treatment, added value utilization of the solid waste is realized, the problems that the environment pollution is generated by the solid waste mud, cultivated land is occupied due to piling of the mud can be solved, and the method has objective economic benefit and application value.

Description

technical field [0001] The invention relates to the field of architectural ceramic materials, in particular to an ancient green brick fired from river mud and a preparation method thereof. Background technique [0002] River silt is one of the solid wastes. Due to the direct discharge of sewage for many years, a large amount of inorganic and organic matter has accumulated in the river mud. Through diffusion and exchange with the overlying water body, it becomes a secondary pollution source and causes environmental pollution. and other secondary pollution issues. my country has also launched a large number of dredging works. Although the problem of river pollution can be solved to a large extent, it has also produced a large amount of follow-up environmental problems that cannot be treated and resettled. Therefore, how to effectively and recycle solid waste river silt, Turning waste into wealth, avoiding secondary environmental pollution, and reusing resources with added valu...

Problems solved by technology

my country has also launched a large number of dredging works. Although the problem of river pollution can be solved to a large extent, it has also produced a large amount of follow-up environmental problems that cannot be treated and resettled. Therefore, how to effectively and recycle solid waste river silt, Turning waste into wealth, avoiding secondary environmental pollution, and reusing resources with added value have become hot issues in current research

[0003] Blue brick is an ancient architectural ceramic material in my country, and it is also a manifestation of my country's architectural culture. Buildings using blue brick as building materials have Chinese traditional cultural characteristics; Ancient blue bricks are obtained by oxidizing flame firing, but white china clay is a non-renewable resource, and the distribution of mineral sources is relatively regional, and the mining cost is relatively high. Most of them are transported across regions when used, which increases the transportation cost; another method is to use Iron-containing clay is used to make blanks and fired in reduction flame kilns. However, due to the large loss of clay, the national policy has restricted its mining and use. This method faces the status quo of no soil.
