Sintered porous brick and preparation method thereof

Abstract

The invention discloses a sintered porous brick and a preparation method thereof. The sintered porous brick comprises the following components in percentage by weight: 68-70 percent of shale and 32-30percent of tailing powder (sewage and sludge). The preparation method comprises the following steps: (1) mining and transporting; (2) processing raw materials; (3) forming; and (4) drying and roasting. The product eliminates the lag production process of the traditional clay sintered brick so as to greatly improve the product quality. A great quantity of cultivated land is saved and the land resources are effectively protected due to the change of the raw materials. Meanwhile, a great quantity of bits of wood (bits of bamboo) greatly improves the environment definitely.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and more specifically relates to a sintered porous brick and a preparation method thereof. Background technique

[0002] According to the relevant requirements of the national building energy-saving aspects, it is of great significance to develop energy-saving and thermal insulation wall materials. Various insulation wall materials currently used, such as various bricks, need to use a large amount of cultivated clay when making them, which is not in line with the national policy of establishing a conservation-minded society. It is very necessary to develop and produce building materials that save cultivated land, save energy, have low cost, and are used for load-bearing and thermal insulation. Contents of the invention
