Problems solved by technology

However, since sand and gravel are non-renewable resources in the natural ecology, more and more concrete is used in construction, and these non-renewable resources will gradually decrease, resulting in irreversible damage to the ecological environment
Moreover, concrete is usually mixed by a mixer when it is prepared, but the mixing effect of the existing mixing equipment is poor, and the materials often agglomerate during the mixing process, which affects the use effect of the concrete in the later stage; and when the concrete is prepared, it is necessary to use a lot of water

Embodiment 1

[0033]A method for preparing concrete for building construction based on resource reuse, comprising the following steps: (1) acquisition of raw materials: obtaining sludge, construction waste, coal ash, and cement, and putting them into mixing equipment at a ratio of 1:1.5:1.2:2.5; Specifically, the sludge is the sediment in the primary sedimentation tank of sewage treatment, which is obtained by scraping the mud scraping equipment. The mud scraping equipment can be realized in the prior art, so it will not be described in detail; secondly, the sludge is Before putting it into the mixing equipment, deodorize the sludge. The specific operation is as follows: put calcium oxide into the sludge at a ratio of 2:1, stir and mix evenly with a rake, and let it stand for 20 minutes; after the stand is completed, Find a concrete floor outdoors, spread the sludge on the concrete floor with a rake, and then dry it in the sun and air-dry until the sludge hardens naturally; then put the air-...

Embodiment 2

[0041] A method for preparing concrete for building construction based on resource reuse, comprising the following steps: (1) Acquisition of raw materials: obtaining sludge, construction waste, coal ash, and cement, and putting them into mixing equipment at a ratio of 1:1.3:1.1:2.3, The structure of the stirring equipment is the same as in Example 1, so it will not be repeated; specifically, the sludge is the sediment in the primary sedimentation tank of sewage treatment, which is obtained by scraping the mud scraping equipment, and the mud scraping equipment is The existing technology can be realized, so it will not be described in detail; secondly, before the sludge is put into the mixing equipment, the sludge is deodorized, and the specific operations are as follows: drop calcium oxide into the sludge in a ratio of 2:1, After mixing evenly with a rake, let it stand for 25 minutes; after the rest is completed, find a piece of cement floor outside, and then spread the sludge o...

Embodiment 3

[0044] A method for preparing concrete for building construction based on resource reuse, including the following steps: (1) Raw material acquisition: obtain sludge, construction waste, coal ash, and cement, and put them into a mixing device at a ratio of 1:1.5:1.2:2.5, The structure of the stirring equipment is the same as in Example 1, so it will not be repeated; specifically, the sludge is the sediment in the primary sedimentation tank of sewage treatment, which is obtained by scraping the mud scraping equipment, and the mud scraping equipment is The existing technology can be realized, so it will not be described in detail; secondly, before the sludge is put into the mixing equipment, the sludge is deodorized, and the specific operations are as follows: drop calcium oxide into the sludge in a ratio of 2:1, After mixing evenly with a rake, let it stand for 30 minutes; after the rest is completed, find a piece of cement floor outside, then spread the sludge on the cement floo...

Abstract

The invention discloses a building construction concrete preparation method based on resource reuse. The preparation method comprises following steps: (1), acquisition of raw materials: adding sludge,construction waste, coal ash and cement to stirring equipment; (2), stirring: adding water to the stirring equipment, starting the stirring equipment, introducing air to a stirring shaft in a stirring process, and producing outwards ejected airflow on the stirring shaft and impacting materials in the stirring equipment; and (3), performance enhancement: adding reinforcing fibers to the materialsobtained by stirring in step (2), and continuing stirring to obtain a finished product. With adoption of the sludge, the construction waste and the coal ash as the raw materials, waste of non-renewable resources such as gravel, sand and the like is effectively reduced; and the stirring shaft can eject air outwards in the stirring process, the condition of caking of the materials is effectively prevented, the materials are mixed more uniformly, and therefore, the prepared concrete has better performance.

Description

technical field [0001] The invention belongs to the technical field of concrete production, and in particular relates to a method for preparing concrete for building construction based on resource reuse. Background technique [0002] Concrete is one of the most important civil engineering materials today. Concrete is produced by mixing sand, gravel and cement. However, since sand and gravel are non-renewable resources in the natural ecology, more and more concrete is used in construction, and these non-renewable resources will gradually decrease, causing irreversible damage to the ecological environment. Moreover, concrete is usually mixed by a mixer when it is prepared, but the mixing effect of the existing mixing equipment is poor, and the materials often agglomerate during the mixing process, which affects the use effect of the concrete in the later stage; and when the concrete is prepared, it is necessary to Use a lot of water resources. Contents of the invention ...
