Abstract

The invention discloses an energy-saving sintering heat-reserving brick, relating to the field of brickmaking by using waste materials. The brick comprises the following components and content in weight percentage: 20-65% of building wastes, 5-40% of river mud, 5-30% of papermaking mud, 5-50% of shale powder, 5-30% of coal ash, 5-20% of coal cinder, 5-20% of saw powder and 5-30% of sediments of asewage treatment plant. The building wastes, the shale and the coal ash are used as the raw materials, so that the thermal insulation property of finished bricks are greatly improved, the waste materials are changed into things of value, and thus, the invention saves cost and increases economic benefits.

Description

technical field [0001] The invention relates to the field of brick making from waste materials, in particular to energy-saving sintered heat insulating bricks. Background technique [0002] In the field of paper industry, a large amount of sludge produced by paper mills has brought serious pollution to the environment. With the increasing requirements of the country for industrial environmental protection, how to deal with the huge amount of sludge produced by the paper industry every year has become more and more important. become the focus of attention. If incineration is used, it will not only pollute the atmosphere, but also consume a lot of energy; if it is filled up, it will pollute groundwater resources. Therefore, how to deal with paper mill sludge has become an environmental protection problem that needs to be solved urgently in the field of paper industry. [0003] Coal slag is a kind of industrial solid waste, also known as slag, which is discharged from thermal...
