Problems solved by technology

However, the mining and processing of natural stone will have an irreversible impact on the ecological environment, and the quality of natural stone will be restricted by the mineral source, and its mining will affect the ecological environment; therefore, there have been calls to use artificial stone to replace natural stone
However, imitation stone, which is mainly made of resin-based materials, has poor weather resistance and is difficult to use outdoors; the existing cement-based imitation stone is mainly wet-processed, and its impact on the environment has been criticized by people.

preparation example Construction

[0024] In addition, the application also provides a method for preparing concrete imitation stone bricks, which specifically includes the following steps:

[0025] S1, stirring.

[0026] Weigh each component material of the base layer, place it in a stirrer, and stir evenly; put each component material of the surface layer together in a surface layer stirrer, and stir evenly.

[0027] S2. After mixing the components of the base layer, place the cloth on the bottom of the mold, press the pressure head slightly, and leave a space about 10mm deep on the upper part of the mold frame.

[0028] S3. Mix the components of the surface layer and fill the reserved space of the mold frame so that they are located on the surface of the base layer. The mold head presses down, vibrates and presses to form, and then demoulds.

[0029] S4. Bricks enter the curing kiln for 24 hours of steam curing or 28 days of room temperature curing.

[0030] S5. The brick body is taken out of the kiln, and...

Abstract

The invention relates to the field of building materials, particularly relates to a concrete stone imitation brick and a method for preparing the same, and belongs to concrete products. The concrete stone imitation brick comprises base layers and surface layers. The base layers comprise, by weight, 40-80 parts of graded crush stone, 12-28 parts of base layer inorganic cementing materials, 4-8 parts of base layer water and 0.1-0.4 part of base layer water reducing agents; the surface layers comprise, by weight, 35-65 parts of compound fine sand with the particle sizes of 10-120 meshes, 10-40 parts of color stone with the particle size smaller than 5 mm, 15-30 parts of surface layer inorganic cementing materials, 4-8.7 parts of surface layer water and 0.1-0.4 part of surface layer water reducing agents. The concrete stone imitation brick and the method have the advantages that the concrete stone imitation brick prepared by the aid of the method is not constrained by mineral resources; the concrete stone imitation brick is excellent in compactness and weather resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete imitation stone brick and a preparation method thereof. Background technique [0002] With the progress of modern urbanization, people's demand for urban construction is getting higher and higher, and it is necessary to take into account the comfort of living and the harmony with the environment. As a building material with a long history, stone plays an irreplaceable role in the aesthetics and comfort of buildings, and is widely used in the renovation of old urban areas and the construction of new urban areas. However, the mining and processing of natural stone will have an irreversible impact on the ecological environment, and the quality of natural stone will be restricted by the mineral source, and its mining will affect the ecological environment; therefore, there have been calls to use artificial stone to replace natural stone. However, imitation stone, which i...
