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, 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 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 put into the stirring equipment Before internal treatment, 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 then let it stand for 20 minutes; Cement floor, then spread the sludge on the concrete floor with a rake, and then dry it in the sun and air-dry until the sludge is naturally air-dried and hardened; then put the air-dried sludge into the crusher for crushing, crushing...

Embodiment 2

[0041] A method for preparing concrete, 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 mixing equipment The structure is the same as that in Example 1, so it will not be described in detail; 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 available in the prior art Realized, so no more details; Secondly, before the sludge is put into the mixing equipment, the sludge is deodorized. The specific operation is as follows: put calcium oxide into the sludge in a ratio of 2:1, and stir and mix it with a rake. After uniformity, let it stand for 25 minutes; after the rest is completed, find a piece of cement floor outside, then spread the sludge on the cement floor with a rake, and then let it air dry...

Embodiment 3

[0044] A method for preparing concrete, 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, the mixing equipment The structure is the same as that in Example 1, so it will not be described in detail; 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 available in the prior art Realized, so no more details; Secondly, before the sludge is put into the mixing equipment, the sludge is deodorized. The specific operation is as follows: put calcium oxide into the sludge in a ratio of 2:1, and stir and mix it with a rake. After it is uniform, let it stand still for 30 minutes; after the standing is completed, find a piece of cement floor outside, then spread the sludge on the cement floor with a rake, and then l...

Abstract

The invention discloses a method for preparing concrete, comprising the following steps: (1) material obtaining: taking sludge, construction waste, coal ash and cement and putting into stirring equipment; (2) stirring: pouring water into the stirring equipment and starting the stirring equipment, and introducing air into a stirring shaft in the stirring process, so that outwards sprayed airflow isgenerated on the stirring shaft and impacts the material in the stirring equipment; (3) performance improvement: adding reinforcing fiber to the material obtained by stirring in step (2) and furtherstirring to obtain the finished product. According to the invention, sludge, construction waste and coal ash are adopted as materials, so that waste of non-renewable resources such as gravels and sandis effectively reduced; and the stirring shaft can spray air to outwards in the stirring process, so that the condition of caking of the material is effectively prevented, the material is mixed moreuniformly, and therefore, the prepared concrete is better in 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. 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 [0003] In order to overcome the deficiencies of th...
