Problems solved by technology

Due to the use of clay as a material for traditional clay fired bricks, a large amount of land has been destroyed. In order to protect cultivated land, the state has issued repeated orders to prohibit and use clay fired bricks. Therefore, the production and use of clay fired bricks will be limited.
Unburned bricks made of industrial waste residues turn waste into treasure and add color to building bricks. However, these products are prone to cracks and leaks. The brick body is not strong and its heat transfer coefficient is large. Design that is not conducive to building energy saving

Embodiment 1

[0043] Example 1, a stone powder sludge sintered brick of the present invention adopts the following components and weight percentages:

[0044] Stone powder sludge 80

[0045] Binder 20

[0046] Among them, the stone powder sludge is the waste material produced in the process of sawing, cutting and grinding of granite. The distribution of granite particles according to the particle size is as follows:

[0047] Less than 0.05mm 50%

[0048] 0.05~1.2mm 35%

[0049] 1.2~2mm 15%;

[0050] The binder is sea silt.

[0051] A manufacturing method of the above-mentioned stone powder sludge sintered brick, which includes the following steps:

[0052] Step a. Ingredients: weigh granite powder sludge and sea silt at 80:20;

[0053] Step b. Stirring: Put the above-mentioned granite powder sludge and sea sludge into a mixer and add water to fully stir them into raw materials for billet making. The moisture content of the billet is 15-20%

[0054] Step c. billet making: send the above-mentione...

Embodiment 2

[0058] The second embodiment is that a stone powder sludge sintered brick of the present invention is different from the first embodiment in that it uses the following components and weight percentages:

[0059] Stone powder sludge 60

[0060] Binder 40

[0061] Stone powder sludge is waste produced in the process of sawing, cutting and grinding of granite and marble. Among them, granite powder accounts for 85% and marble powder accounts for 15%; the particles of stone powder sludge are distributed according to the particle size. as follows:

[0062] Less than 0.05mm 30%

[0063] 0.05~1.2mm 50%

[0064] 1.2~2mm 20%.

Embodiment 3

[0065] The third embodiment is a kind of stone powder sludge sintered porous brick of the present invention, which uses the following components and weight percentages:

[0066] Stone powder sludge 50

[0067] Binder 30

[0068] Internal fuel 20

[0069] Among them, stone powder sludge is waste generated during the sawing, cutting, and grinding of granite and marble. Granite powder sludge accounts for 90%, and marble powder sludge accounts for 10%; the binder is construction waste soil. ; The internal fuel is slag.

[0070] The particle size distribution of stone powder sludge is as follows:

[0071] Less than 0.05mm 35%

[0072] 0.05~1.2mm 60%

[0073] 1.2~2mm 5%.

[0074] A method for manufacturing the above-mentioned stone powder sludge sintered porous brick includes the following steps:

[0075] Step a1. Crushing: crushing the slag into granules, the particle size of the granules is not greater than 2mm;

[0076] Step a. Ingredients: weigh the stone powder sludge, construction w...

Abstract

The present invention discloses one kind of stone powder sludge sintering brick and its production process. The stone powder sludge sintering brick is produced with stone powder sludge from stone material producing process as main material, sludge from river, lake or sea, building waste clay or clay as adhesive, slag, coal slack, fly ash or coal as inner material, and through crushing, stirring, forming adobe, drying, roasting and other steps. The present invention has the features of waste utilization, environment friendship, saving in soil, low power consumption, high compression strength, etc. It may be used in replacing sintered clay brick.

Description

Technical field [0001] The invention relates to a building material, in particular to a stone powder sludge sintered brick produced by using stone powder sludge as a raw material and a manufacturing method thereof. Background technique [0002] Brick is a commonly used building material. Bricks are usually divided into sintered bricks and non-sintered bricks. All bricks made by firing are called sintered bricks, such as clay sintered bricks, sintered hollow bricks, etc. Clay sintered bricks are mainly made of clay as raw material through batching, modulation, drying, and high-temperature roasting; cement and lime are used as raw materials. The bricks made of raw materials are non-burning bricks, such as lime-sand bricks and cement porous bricks. Traditional clay sintered bricks have been destroyed due to the use of clay as a material. In order to protect arable land, the state has repeatedly banned and used clay sintered bricks. Therefore, the production and use of clay sintered ...
