Embodiment 1

[0020] A preparation method of floating bed lightweight aggregate, comprising the following steps:

[0021] (1) First mix 5 parts by weight of bamboo charcoal powder and 1 part of water for 10-30 seconds, then add 5 parts by weight of foaming agent and mix for 10-30 seconds, and finally add 5 parts of deinking waste slag fiber, 10 parts of cement and 4 parts of water are mixed uniformly to obtain lightweight aggregate slurry. Bamboo charcoal powder has a lightweight porous structure with water retention properties, and is resistant to alkali erosion caused by cement hydration. It can effectively retain water when mixed with water in advance, and then mixed with foaming agent, so that the foaming agent wraps the surface of bamboo charcoal powder, which can ensure foaming. The foaming agent fully reacts with water to form cells.

[0022] (2) The lightweight aggregate slurry is made into a square plate with a thickness of 1cm, and the square plate is kept at 40°C for 1 hour, and...

Embodiment 2

[0029] Another preparation method of floating bed lightweight aggregate comprises the following steps:

[0030] (1) First mix 10 parts by weight of bamboo charcoal powder and 4 parts of water for 10-30 seconds, then add 10 parts by weight of foaming agent and mix for 10-30 seconds, and finally add 10 parts of deinking waste slag fibers, 20 parts of cement and 6 parts of water were uniformly mixed to obtain lightweight aggregate slurry.

[0031] (2) Make the lightweight aggregate slurry into a square plate with a thickness of 3cm, keep the square plate at 60°C for 1 hour, and then maintain it at 3MPa for 4 hours.

[0032] (3) Cut the cured square plate into a cube with a side length of 3 cm, and use ceramic grinding balls to grind for 30 minutes to remove edges and corners, and obtain a light aggregate body close to a sphere and light aggregate powder produced during the grinding process body.

[0033] (4) Mix 50 parts by weight of cement, 4 parts of lightweight aggregate pow...

Embodiment 3

[0037] Another kind of preparation method of floating bed lightweight aggregate, is characterized in that, comprises the following steps:

[0038] (1) First mix 7 parts by weight of bamboo charcoal powder and 3 parts of water for 10-30 seconds, then add 8 parts by weight of foaming agent and mix for 10-30 seconds, and finally add parts by weight 7 parts of deinking waste slag fibers, 15 parts of cement and 5 parts of water were uniformly mixed to obtain lightweight aggregate slurry.

[0039] (2) Make the lightweight aggregate slurry into a square plate with a thickness of 2cm, keep the square plate at 50°C for 1 hour, and then maintain it at 2MPa for 4 hours.

[0040] (3) Cut the cured square plate into a cube with a side length of 2 cm, and use ceramic grinding balls to grind for 20 minutes to remove edges and corners, and obtain a light aggregate body close to a sphere and light aggregate powder produced during the grinding process body.

[0041] (4) Mix 40 parts by weight...

Abstract

The invention discloses a floating floor lightweight aggregate and a preparation method thereof. The preparation method of the floating floor lightweight aggregate comprises the following steps: firstly, mixing bamboo carbon powder with water, further adding a foaming agent, and finally adding a solid reject fiber, cement and water, and uniformly mixing so as to obtain lightweight aggregate slurry; manufacturing square plates from the lightweight aggregate slurry, maintaining, cutting into cubes, and polishing to remove cubic corner angles so as to obtain lightweight aggregate blanks and lightweight aggregate powder generated in the polishing process; uniformly mixing cement, the lightweight aggregate powder, cellulose ether and water so as to obtain surface slurry; and blowing the surface slurry to the lightweight aggregate blanks from bottom to top by using an air blower, and performing surface slurry coating on the lightweight aggregate blanks, thereby obtaining the floating floor lightweight aggregate. A floating floor made of the floating floor lightweight aggregate disclosed by the invention is free of phenomenon of bottom slurry settlement or hole blocking, and meanwhile, the stormy wave impact resistance can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of floating beds, and in particular relates to a floating bed lightweight aggregate and a preparation method thereof. Background technique [0002] The floating bed originally refers to a natural phenomenon in which part of the plants on the lakeshore is cut off and floats on the water surface due to the upward floating of the peat layer. With the development of science and technology, artificial floating beds appear, on which reeds and other aquatic plants are cultivated, and long-term placement in the water can purify water quality, create living spaces for creatures (birds, fish), improve landscapes, and produce wave-absorbing effects to protect embankments. , especially the concrete floating bed, uses the pores formed by the aggregate accumulation to provide space for the growth of plant roots, the plant planting density is high, and there is no secondary pollution. [0003] At present, polystyrene part...
