Abstract

The invention discloses a sludge and silt sintered brick with a chamotte brick surface layer and a preparation method thereof. The sintered brick contains two layered brick bodies, namely an upper clay sintered layer and a lower sludge and silt sintered layer. The thickness of the clay sintered layer is 1-20mm and contains the following raw materials of: by weight, 70-85% of clay and 15-30% of internal fuel. The sludge and silt sintered layer contains the following raw materials of: by weight, 40-70% of river and lake sludge, 10-35% of urban sludge and 15-30% of internal fuel. By the adoption of the sintered brick prepared in the invention, the problem that the wall composed of the sludge and silt sintered bricks is easy to crack and the plaster is easy to hollow can be effectively improved.

Description

technical field [0001] The invention specifically relates to a silt sludge fired brick with a clay brick surface layer and a preparation method thereof. Background technique [0002] my country's construction industry has a huge demand for sintered bricks. In the past, sintered bricks were prepared by excavating farmland clay and sintering, which resulted in a large loss of soil resources and serious destruction of fields. At present, the country has banned the use and production of clay solid bricks, and the use of mud and sludge to make bricks has become a trend to replace clay bricks. [0003] However, due to the limitation of the material of silt and sludge itself, it is easy to crack the wall and the plaster is easy to hollow. In practical application, the performance of the original clay brick cannot be achieved. Contents of the invention [0004] The object of the present invention is to provide a kind of sintered brick whose outer wall is not easy to c...
