Embodiment 1

[0022] A spreadable iron-carbon composite filler powder for concrete is composed of the following raw materials in parts by weight: 30 parts of iron-carbon, 30 parts of zeolite, 20 parts of ceramsite, 10 parts of anthracite and 10 parts of volcanic rock. Put each component into a crusher for crushing, then into a pulverizer, pass through a 1mm sieve, and finally add each component into a compounding tank, stir evenly to obtain the filler powder. After the concrete has just been poured and put into the mold, the prepared iron-carbon composite filler powder is evenly sprinkled on the upstream surface of the concrete, with a thickness of 5mm, and then wait for the concrete to harden, and the powder is firmly bonded to the concrete surface.

Embodiment 2

[0024] A spreadable iron-carbon composite filler powder for concrete is composed of the following raw materials in parts by weight: 30 parts of iron-carbon, 40 parts of zeolite, 10 parts of ceramsite, 10 parts of anthracite and 10 parts of volcanic rock. Put each component into a crusher for crushing, then into a pulverizer, pass through a 1mm sieve, and finally add each component into a compounding tank, stir evenly to obtain the filler powder. After the concrete has just been poured and put into the mold, the prepared iron-carbon composite filler powder is evenly sprinkled on the upstream surface of the concrete, with a thickness of 5mm, and then wait for the concrete to harden, and the powder is firmly bonded to the concrete surface.

Embodiment 3

[0026] A spreadable iron-carbon composite filler powder for concrete is composed of the following raw materials in parts by weight: 32 parts of iron-carbon, 30 parts of zeolite, 12 parts of ceramsite, 10 parts of anthracite, and 16 parts of volcanic rock. Put each component into a crusher for crushing, then into a pulverizer, pass through a 1mm sieve, and finally add each component into a compounding tank, stir evenly to obtain the filler powder. After the concrete has just been poured and put into the mold, the prepared iron-carbon composite filler powder is evenly sprinkled on the upstream surface of the concrete, with a thickness of 5mm, and then wait for the concrete to harden, and the powder is firmly bonded to the concrete surface.

Abstract

The invention discloses spreading type iron-carbon composite filler powder for concrete. The spreading type iron-carbon composite filler powder is prepared from 30-40 parts of iron carbon, 30-40 partsof zeolite, 10-20 parts of ceramsite, 10-20 parts of anthracite and 10-20 parts of volcanic rock. The preparation method comprises the following steps: sequentially putting the components into a crusher and a pulverizer for treatment, sieving with a 1mm sieve, adding the components into a compounding tank, and uniformly stirring to obtain the filler powder. The method is wider in application range, and can be applied to all concrete areas where sewage passes through; concrete poured into structures such as the constructed wetland can meet the high requirements for seepage prevention, crack resistance and the like, meanwhile, the capabilities of purifying water, removing harmful substances such as nitrogen and phosphorus in sewage and the like are achieved, and multiple purposes can be achieved.

Description

technical field [0001] The invention belongs to the field of sewage treatment technology, composite filler and concrete engineering, and in particular relates to the application of a spread-type iron-carbon composite filler powder for concrete. Background technique [0002] After the nitrogen and phosphorus nutrients in the sewage enter relatively closed waters, they can easily lead to eutrophication of water bodies under sunlight. Throughout the world, almost all lakes and other recreational water bodies have varying degrees of eutrophication, and most areas are quite serious. As an emerging sewage treatment process, constructed wetland has the characteristics of simple maintenance, good effect, and wide application. It is a wetland treatment system that has been widely studied and applied in the world. Constructed wetlands remove pollutants in water through various methods. For example, fillers remove pollutants in sewage through physical and chemical actions such as adso...
