Embodiment 1

[0017] A preparation method of the building bricks, comprising the steps of:

[0018] (1), get 50 parts of stone powder slag, 40 parts of sea mud, 15 parts of fly ash and 15 parts of shale, stir and mix, then add water of 5% of the total weight of the mixed material, and stir to form a slurry;

[0019] (2), the slurry that step (1) is made is transported in the brick mould, carries out mechanical molding, obtains brick adobe;

[0020] (3), the adobe is dried in the drying device, or dried naturally, to a moisture content of 38%;

[0021] (4) The brick adobe dried in step (3) is placed in a kiln for firing at a temperature of 1200° C. for 24 hours; then the temperature is controlled at 1000±20° C. for 48 hours to obtain building bricks.

Embodiment 2

[0023] A preparation method of the building bricks, comprising the steps of:

[0024] (1), get 70 parts of stone powder slag, 30 parts of sea mud, 20 parts of fly ash and 10 parts of shale, stir and mix, then add water with 5% of the total weight of the mixed material, and stir to form a slurry;

[0025] (2), the slurry that step (1) is made is transported in the brick mould, carries out mechanical molding, obtains brick adobe;

[0026] (3), the adobe is dried in the drying device, or dried naturally, until the moisture content is 35%;

[0027] (4) The brick adobe dried in step (3) is placed in a kiln for firing at a temperature of 950° C. for 24 hours; then the temperature is controlled at 1000±20° C. for 48 hours to obtain building bricks.

Embodiment 3

[0029] A preparation method of the building bricks, comprising the steps of:

[0030] (1), get 60 parts of stone powder slag, 35 parts of sea mud, 18 parts of fly ash and 12 parts of shale, stir and mix, then add water of 5% of the total weight of the mixed material, and stir to form a slurry;

[0031] (2), the slurry that step (1) is made is transported in the brick mould, carries out mechanical molding, obtains brick adobe;

[0032] (3), the adobe is dried in the drying device, or dried naturally, until the moisture content is 30%;

[0033] (4) The adobe dried in step (3) is placed in a kiln for firing at a temperature of 1000° C. for 24 hours; then the temperature is controlled at 1000±20° C. for 48 hours to obtain building bricks.

Abstract

The invention discloses a preparation method of a brick for construction, which comprises the following steps of: (1) mixing materials: respectively weighting various raw materials containing 50 to 70 parts by weight of stone powder, 30 to 40 parts by weight of sea mud, 15 to 20 parts by weight of pulverized fuel ash and 10 to15 parts by weight of shale, mixing uniformly, adding water accounting for 3% to 8% of the total weight of the mixed material , and then stirring the mixed material into slurry; (2) making a green brick: conveying the slurry prepared in step (1) to a brick mould to be mechanically mould pressed to obtain the green brick ; (3) drying: drying the green brick in a drying device or naturally drying the green brick in the sun until the water content of the green brick is less than 40%; and (4) sintering: sintering the dried green brick dried in step (3) in a kiln to obtain the brick for construction. The brick for construction is made from three materials containing stone powder as a construction waste, unlimited amount of sea mud and pulverized fuel ash as raw materials in the preparation method, has high compressive strength, good folding resistance and shock-resisting function, and has the characteristics of light weight, heat preservation, heat insulation, fire prevention and the like.

Description

technical field [0001] The invention relates to a wall material, in particular to a building brick and a preparation method of the brick. Background technique [0002] The existing building walls are mainly made of clay bricks, and the materials used are cultivated soil, which consume a large amount of land resources. The original clay bricks obviously do not meet the national industrial policy and are not conducive to the strategic requirements of resource and environmental protection and sustainable development. Therefore, it is the general trend to use new wall materials to replace clay bricks. At the same time, in the coastal economically developed areas, there are a large number of stone processing enterprises, which produce a large amount of stone powder and slag every day, which has become a public hazard for environmental protection and ecological construction. Seriously affect local production, life and people's health. More importantly, the compressive strength ...
