Embodiment 1

[0010] A modified cement brick is composed of the following components in parts by weight: 25 parts by weight of cement, 12 parts of magnesium chloride, 7 parts of calcium sulfate, 50 parts of fly ash, 30 parts of yellow sand, 20 parts of cinder and 13 parts of plant fiber.

Embodiment 2

[0012] A modified cement brick is composed of the following ingredients in parts by weight: 20 parts by weight of cement, 16 parts of magnesium chloride, 5 parts of calcium sulfate, 60 parts of fly ash, 20 parts of yellow sand, 30 parts of cinder and 10 parts of plant fiber.

Embodiment 3

[0014] A modified cement brick is composed of the following components in parts by weight: 30 parts by weight of cement, 8 parts of magnesium chloride, 9 parts of calcium sulfate, 40 parts of fly ash, 40 parts of yellow sand, 10 parts of cinder and 16 parts of plant fiber.

[0015] The production method of the above product is as follows: stirring and mixing each component according to the proportion, adding an appropriate amount of water to make a slurry, injecting into a mold to vibrate, condensing and curing for 3 days, demoulding, and drying.

[0016]

[0017] The cement brick prepared by the invention has the functions of high wear resistance and high anti-skid, which reduces the risk of easily slipping and falling when the floor brick is wet. After testing, the product's technical standards meet the requirements.

Abstract

The invention discloses a modified cement brick, made from, by weight, 20-30 parts of cement, 8-16 parts of magnesium chloride, 5-9 parts of calcium sulfate, 40-60 parts of flyash, 20-40 parts of yellow sand, 10-30 parts of coal residue, and 10-16 parts of plant fibers. The modified cement brick has the advantages that the finished brick has low chances for cracking owing to tight adhesion; the brick has good water resistance and acid resistance, high cracking strength and high breaking strength and is free of deforming or shading; the color, shape and material of the brick may be designed as required, and the brick features low cost, environmental friendliness and meeting the industrial policy of sustainable development; the brick is widely applicable to decorations for walls, grounds, furniture surface and the like.

Description

technical field [0001] The invention relates to the technical field of cement bricks, in particular to a modified cement brick. Background technique [0002] With the development of the country's economic life, the materials used in interior and exterior design have involved various industries such as steel, non-ferrous metals, chemicals, textiles, wood, ceramics, plastics, and glass. People's emphasis and emphasis on the spirit of the theme of interior and exterior design also requires new materials with great personality and moderate cost to realize. As far as wall and floor decoration is concerned, there are many types of materials that can be used, such as ceramic glazed tiles, marble, and granite facing tiles. However, the above-mentioned materials are difficult to make new breakthroughs in decorative effects, and the cost is high. It is quite necessary to develop decorative bricks with low cost, good performance, environmental protection, and in line with national dev...
