Unitary decorative blocks cut from concrete blanks and their production

Abstract

The invention is about decorative brick used in indoor-outdoor wall face and ground ornament which is acted as the overall structure and produced through dressing after the dimidiate concrete body. Compared with the existing concrete complex structure decorative brick, it's shrinkage breakup is difficult, service life is long, technology is simple, production cycle is short and cost is low. The decorative surface is shaped through dressing to the dimidiate cement body. Therefore the colorful stone cross-section in the concrete body open naturally. The external appearance is like the crude 'zimu stone'. It is simple and natural. The decorative impression is novel. It is the perfect decorative stuff of wall face and ground.

Description

1. Technical field

[0001] The invention relates to the technical field of building wall surface and floor decoration products, and more specifically relates to the technical field of concrete material building wall surface and floor decoration bricks. 2. Background technology

[0002] The concrete decorative bricks widely used in reality are composed of a surface layer (decorative layer) and a base layer (structural layer). The surface layer concrete is made of fine aggregates such as cement and river sand. The decorative effect of the product is mainly determined by the surface layer. The color and the stripes and patterns on the surface layer are reflected. Although the concrete wall and floor decorative bricks of the prior art have their own characteristics and are widely accepted and used in practice, their deficiencies are also very obvious. First, since the facing layer is made of fine aggregates such as cement and river sand, the facing layer of decorative bricks is ...

Embodiment 1

[0032] The component formula of the decorative brick concrete body is: the label is 400 # 1 part of ordinary Portland cement, 0.5 part of stone powder with a mud content of less than 2%, 0.6 part of fine aggregate stone with a mud content of less than 2%, coarse aggregate stone with a particle size of less than 15cm and a mud content of less than 1% 2.0 parts, 0.02 parts of brightener (ie water reducing agent), 0.40 parts of water. The prepared component raw materials are added into the mixer, fully stirred and mixed, and poured into the steel mold that can be split into two decorative brick bodies to prepare the concrete body. Forming takes the form of vibration forming. After forming, carry out curing with the mold first, and cure until it is suitable for demoulding to remove the mold, and then carry out curing with water, and cure until the concrete body is suitable for cutting. After curing, split the concrete body into two pieces of decorative brick body, then scrape th...

Embodiment 2

[0034] The component formula of the decorative brick concrete body is: the label is 400 # 1 part of aluminum sulfate quick-hardening cement, 0.8 parts of stone powder with a mud content of less than 2%, 1.0 part of finely aggregated stone with a mud content of less than 2%, 3.0 parts of natural gravel with a mud content of less than 1% and a maximum particle size of less than 10cm 0.005 parts of high-efficiency water reducer named "FDN", 0.4 parts of iron oxide red, and 0.55 parts of water. The processing technology method of decorative brick is identical with embodiment 1.

Embodiment 3

[0036] The component formula of the decorative brick concrete body is: the label is 400 # 1 part of ordinary Portland cement, 0.6 parts of stone powder with a mud content of less than 2%, 0.8 parts of finely aggregated stone with a mud content of less than 2%, 2.0 parts of natural pebbles with a maximum particle size of less than 12cm and a mud content of less than 1% , "FDN" superplasticizer 0.01 parts, iron oxide yellow 0.5 parts, water 0.5 parts. The processing technology method of decorative brick is identical with embodiment 1.
