Embodiment 1

[0010] An environment-friendly brick comprises, by weight: 20 parts of coal gangue, 40 parts of construction waste, 10 parts of cinder, 15 parts of granite debris, 5 parts of water and 10 parts of straw.

[0011] A method for preparing an environmentally-friendly brick, comprising the following steps: (1) Using a crusher to crush coal gangue and granite slag into powder with a particle size of 60 mesh, crushing construction waste and coal cinder into particles with a particle size of 40 mesh, and The straw is crushed into 1cm, and then the crushed materials are mixed evenly; (2), the above-mentioned mixed materials are pressed into a brick mould; (3), calcined, the bricks are roasted at 400°C for 2 hours, and then raised Calcined at 1050°C for 10 hours, naturally cooled to 380°C, held for 6 hours, and cooled to obtain environmentally friendly bricks. The compressive strength of environmentally friendly bricks is 15.6MPa, and the porosity of environmentally friendly bricks is 15...

Embodiment 2

[0013] An environment-friendly brick comprises, by weight: 15 parts of coal gangue, 30 parts of construction waste, 5 parts of cinder, 25 parts of granite debris, 5 parts of water and 20 parts of straw.

[0014] A method for preparing an environmentally-friendly brick, comprising the following steps: (1) Using a crusher to crush coal gangue and granite slag into powder with a particle size of 60 mesh, crushing construction waste and coal cinder into particles with a particle size of 40 mesh, and The straw is crushed into 0.5cm, and then the crushed materials are mixed evenly; (2), the above-mentioned mixed materials are pressed into a brick mould; (3), calcined, the made bricks are roasted at 420°C for 2 hours, and then Increase the temperature of the kiln to 1150°C for calcination for 8 hours, naturally lower the temperature to 400°C, keep warm for 8 hours, and cool to obtain environmentally friendly bricks. The sound insulation level at ℃ reaches level 3.

Embodiment 3

[0016] An environment-friendly brick comprises, by weight: 20 parts of coal gangue, 30 parts of construction waste, 10 parts of cinder, 15 parts of granite debris, 10 parts of water and 15 parts of straw.

[0017] A method for preparing an environmentally-friendly brick, comprising the following steps: (1) Using a crusher to crush coal gangue and granite slag into powder with a particle size of 60 mesh, crushing construction waste and coal cinder into particles with a particle size of 40 mesh, and The straw is crushed into 0.5cm, and then the crushed materials are mixed evenly; (2), the above-mentioned mixed materials are pressed into a brick mould; (3), calcined, the made bricks are roasted at 400°C for 2 hours, and then Increase the kiln temperature to 1150°C for calcination for 12 hours, naturally cool down to 400°C, keep warm for 5 hours, and cool to obtain environmentally friendly bricks. The compressive strength of environmentally friendly bricks is 14.2MPa and the porosi...

Abstract

The invention belongs to the field of building materials, and particularly relates to an environmental-friendly brick and a production method thereof. The brick comprises 15-25 parts by weight of coal gangue, 30-40 parts by weight of building rubbish, 5-10 parts by weight of coal cinder, 15-25 parts by weight of granite disintegrated slag, 5-10 parts by weight of water and 10-20 parts by weight of straw. The coal gangue, the building rubbish, the straw, and the like are adopted to produce the brick, thus guaranteeing the strength and the compression resistance of the brick, reducing the weight of the brick and enhancing the sound insulation effect of the brick.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environment-friendly brick and a production method thereof. Background technique [0002] Brick is a kind of building material with the appearance of small cuboid block, which is the main material of the wall. With the development of real estate and the continuous construction of new rural areas, the consumption of bricks is gradually increasing. Traditional bricks are made of clay, which consumes arable land and a lot of energy. They are being phased out and replaced. Take environmentally friendly bricks. Environmentally friendly bricks are made of construction waste, tailings and other raw materials. They have high strength and do not require clay, which protects the cultivated land. However, the quality of environmentally friendly bricks is relatively large, which is inconvenient to use, and the overall quality of the building is relatively low. If it is too ...
