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 includes the following steps: (1) Raw material acquisition: Obtain sludge, construction waste, coal ash, and cement, and put them into mixing equipment at 1:1.5:1.2:2.5; specifically, The sludge is the sediment in the primary sedimentation tank of sewage treatment, which is scraped out by scraping equipment. The scraping equipment is realized by the prior art, so it will not be repeated; secondly, the sludge is put into the mixing equipment Before the inside, the sludge is deodorized. The specific operation is as follows: Put calcium oxide into the sludge at a ratio of 2:1, mix it with a rake, and let it stand for 20 minutes; after the standing is completed, find a piece of it outdoors Cement ground, and then spread the sludge on the cement floor with a rake, then air dry and air dry until the sludge is naturally air-dried and hardened; then put the air-dried sludge into a crusher for crushing and crushing After the completion of the 80-me...

Embodiment 2

[0041] A method for preparing concrete includes the following steps: (1) Raw material acquisition: Obtain sludge, construction waste, coal ash, and cement, and put them into mixing equipment at 1:1.3:1.1:2.3. The structure is the same as that 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 scraped out by a mud scraping device, and the mud scraping device is a prior art. It is realized, so it will not be repeated; secondly, before the sludge is put into the mixing equipment, the sludge is deodorized, and the specific operation is as follows: put calcium oxide into the sludge at a ratio of 2:1, and stir and mix with a rake After uniformity, let stand for 25min; after the rest is complete, find a piece of cement floor outdoors, then spread the sludge on the cement floor with a rake, and then air dry and air dry until the sludge is naturally air-dried and hardened ; Afterwards, the ai...

Embodiment 3

[0044] A method for preparing concrete includes the following steps: (1) Raw material acquisition: Obtain sludge, construction waste, coal ash, and cement, and put them into mixing equipment at 1:1.5:1.2:2.5. The structure is the same as that 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 scraped out by a mud scraping device, and the mud scraping device is a prior art. It is realized, so it will not be repeated; secondly, the sludge is deodorized before being put into the mixing equipment. The specific operation is as follows: Put calcium oxide into the sludge at a ratio of 2:1, and stir and mix with a rake After uniformity, let stand 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 dry it naturally, until the sludge is naturally air-dried and hardened ; Afterwards, the air-drie...

Abstract

The invention discloses a method for preparing concrete, which comprises the following steps: (1) raw material acquisition: obtaining sludge, construction waste, coal ash, and cement and putting them into mixing equipment; (2) mixing: putting them into mixing equipment water and start the stirring equipment, and ventilate the stirring shaft during the stirring process, so that the airflow ejected from the stirring shaft will be generated on the stirring shaft and impact the materials in the stirring equipment; Add reinforcing fibers to the material and continue stirring to get the finished product. In the present invention, sludge, construction waste, and coal ash are used as raw materials, which effectively reduces the waste of non-renewable resources such as gravel and sand; during the stirring process, the stirring shaft can spray air outwards, which effectively prevents the agglomeration of materials , The mixing between the materials is more uniform, so that the performance of the prepared concrete is better.

Description

Technical field [0001] The invention belongs to the technical field of concrete manufacturing, and in particular relates to a method for preparing concrete. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. Concrete needs to be mixed and mixed with sand, gravel and cement during manufacture. However, since sand and gravel are non-renewable resources in the natural ecology, more and more concrete is used in construction. These non-renewable resources will gradually decrease, resulting in irreversible damage to the ecological environment. And the concrete is usually mixed by a mixer during preparation, but the mixing effect of the existing mixing equipment is poor, and the materials often agglomerate during the mixing process, which affects the later use effect of the concrete; and when the concrete is prepared, it is necessary A lot of water resources are used. Summary of the invention [0003] In order to overcome the ...
