Description

Energy-saving brick and preparation method thereof

Technical Field

The invention relates to the field of building materials, in particular to an energy-saving brick and a preparation method thereof.

Background

China is a large country for producing building materials and clay bricks, 15 million solid clay brick manufacturers exist in China in 2016 according to statistics, 8400 million solid clay bricks are produced, about 15 billion cubic meters, each occupied cultivated land is destroyed by more than 100 million acres every year, the solid clay bricks are converted into multifunctional and high-efficiency building materials in the twenty-century fifty years of industrially developed countries, a product structure taking novel building materials as main materials is formed, and the development road of modernization, industrialization and greenization is reached.

In the aspect of building materials, national planning clearly requires ' development of high-quality products is greatly increased and novel building material products are popularized ', ' production and use of clay solid bricks are limited ', and industrial waste residues are actively utilized to produce building materials '. The existing brick sheets or bricks are prepared from stone powder as a main raw material, and all the materials are purchased from the market, so that the cost is high; in recent years, the development and urbanization process of the crystal industry and the acceleration of new rural construction generate a large amount of crystal waste, construction waste and industrial solid waste (tailing slag and treated fly ash), which pollute the environment and occupy land resources, and a large amount of manpower and financial resources are spent to treat the waste and the waste every year, so that the problem of headache of common people is solved.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides an energy-saving brick and a preparation method thereof.

In order to achieve the purpose, the invention adopts the following technical scheme:

an energy-saving brick comprises the following raw materials in parts by weight: 55-65 parts of industrial solid waste, 30-35 parts of crystal waste residue, 8-10 parts of cement and 8-10 parts of water.

Preferably, the preparation method of the energy-saving brick comprises the following steps.

Step 1: collecting industrial solid waste and crystal waste residue materials.

Step 2: respectively crushing the collected industrial solid waste and crystal waste residue materials into 70-90-mesh loose particles by a crusher, and then sieving;

and step 3: and (3) mixing and stirring the loose particles prepared in the step (2) for 20-30 minutes to prepare a dry mixture.

And 4, step 4: and (3) fully mixing and stirring the dry mixture, cement and water to prepare a wet mixture, and placing the wet mixture for 2 hours.

And 5: and (3) pressing the wet mixture after being placed for 2 hours at a pressure of 0-50 MPa.

Step 6: and (5) curing the brick formed in the step (5) by adopting a natural curing method in the sun for seven days to obtain a finished brick.

Preferably, the industrial solid waste adopts construction waste, tailing slag and fly ash.

The energy-saving brick is prepared by collecting building garbage, tailing slag, fly ash and crystal waste residues as raw materials, and processing the raw materials through the working procedures of crushing, sieving, mixing and stirring, profiling, curing and the like, so that a finished brick is prepared.

Drawings

Fig. 1 is a schematic view of a process flow for preparing an energy-saving brick according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1:

The preparation method of the energy-saving brick comprises the following steps:

step 1: collecting industrial solid waste and crystal waste residue materials.

The industrial solid waste adopts building garbage, tailing slag and fly ash as raw materials.

The industrial solid waste and the crystal waste residue are crushed into loose particles which are favorable for mixing and stirring with cement, the cement adopts common portland cement and is used for improving the strength and the water resistance of the brick, the cement does not crack after being soaked in water, the longer the mixing time is, the more uniform the mixing is, the dry mixing time is, the mixing and stirring time is 20 minutes, the strength of the brick is improved by 15 to 23 percent compared with the mixing time of 10 minutes, the wet mixing time is that the material is not agglomerated, the mixed wet mixing material is placed for two hours, the compression strength of the brick can be reduced when the mixing time is too long or too short, the compression molding is carried out under the pressure of 0 to 50MPa during molding, the prepared brick has high compression strength and good water resistance under the pressure of 50MPa, and is not easy to compact; the strength of the brick can be improved by using appropriate water consumption, the molding moisture is less, the strength of the brick is poor, the resistance of wet mixed materials in the mould is large, the wet mixed materials are pressurized unilaterally, the bottom surface of the brick is not compact, the molding moisture is more, the bottom surface of the brick is wet, and the brick is easy to be damaged when being discharged from the mould; the formed brick is placed in the sun for curing, and the age strength of the brick is naturally cured for 7 days in the sun, which is 67-90% of the age strength of 28 days.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
