Description
Technical field
The invention belongs to technical field of concrete preparation, more particularly, to a kind of preparation method for concrete.
Background technique
Concrete is one of the present age most important civil engineering material.It is by cementitious material, granular aggregat, water and
The additive and admixture being added when necessary are prepared by a certain percentage, through uniform stirring, closely knit molding, one made of maintenance hardening
The artificial stone material of kind.Cement concrete is needed using to a large amount of natural sand, rubble during preparation, but these resource categories
It is long-term to exploit and use natural sand and rubble in non-renewable resources, it will being gradually reduced for these non-renewable resources is caused,
It will even influence whether ecological environment, irreversible destruction is caused to ecology.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides one kind and makes full use of resource, energy-saving and environment-friendly to be used for coagulation
The preparation method of soil.
To achieve the goals above, the invention adopts the following technical scheme: a kind of preparation method for concrete；It is described
Concrete is made of the material of following parts by weight: 35-40 parts of cement, 15-20 parts of mud, and 15-20 parts of cinder, construction waste 8-12
Part, 5-8 parts of reinforcing fibre, 2-3 parts of waterproof additive；The reinforcing fibre is made of the material of following parts by weight: glass fibre
5-8 parts, 2-3 parts of polypropylene fibre, 2-3 parts of plastic-steel fabric, 5-6 parts of Corvic；Preparation method the following steps are included:
(1) construction waste is handled: recycled concrete aggregate being cut into bulk by cutting machine, and by drilling machine in bulk
The different location of concrete is punched；By discarded brick, tile is ground into the particle of 80 mesh by stone crusher；It later will be upper
It states construction waste and is mixed to form construction waste A together；
(2) mud deodorization: from river, lake, pond, sedimentation basin, after the place such as moat obtains mud, in the ratio of 1:1.5
Calcium oxide is launched into mud, and carries out standing for 24 hours；Manually mud was stirred using rake every 20-30 minutes during standing
Disorderly；After for 24 hours, mud is dried, so that mud natural air drying；
(3) prepare reinforcing fibre: Corvic be heated to 140 DEG C to soften Corvic, it is backward soft
Glass fibre, polypropylene fibre, plastic-steel fabric are added in the Corvic of change；Continue to be heated to 160 DEG C, sustained response
It after 10-15min, is cooled to room temperature, reinforcing fibre is made；
(4) it prepares waterproof additive: calcium stearate being put into the ratio of 1:21 into ethanol solution, is melted to calcium stearate
After change, then water-reducing agent is put into ethanol solution, calcium stearate, dispersing agent, magnesium lime, swelling agent, obtained waterproof after mixing
Additive；
(5) it mixes: by cement, through step (2) treated mud, cinder, through step (1) treated construction waste,
Through reinforcing fibre made from step (3), put into through waterproof additive made from step (4) into concrete mixer, to stirring
Water is added in machine, starts blender, stirs to get concrete.
The present invention improves resource utilization by effectively reducing the use of sandstone raw material using construction waste as raw material；And
Since construction waste has played use, to effectively reduce building waste to appropriation of land and to soil, the pollution of water body, pole
Big degree improves ecological environment；And different processing is carried out according to different building wastes, give full play to construction waste
Value improves resource utilization；Concrete block is cut into bulk, and hardness is larger, can enhance the secured intensity of pile foundation；Brick and watt
The intensity of piece is lower, to be crushed, is sufficiently mixed with cement, is relatively made for bulk, can more be fully utilized, mention
The utilization rate of high building rubbish；After particle is made simultaneously, the usage amount of cement can be reduced, to save construction cost；And pass through
Drill to concrete block, during concrete formation and solidification, guarantee cement can through hole enter to coagulation
In soil block, enhances the firmness of the connection between concrete block and cement, effectively improve the intensity of concrete；Mud is passing through dispensing
After calcium oxide, the peculiar smell in mud will be effectivelyed removed, and prevent from containing peculiar smell in last concrete obtained.
Mud is used in the present invention, cinder, the materials such as construction waste prepare cement concrete, to effectively reduce day
The use of right sand and rubble, effectively reduces the waste to non-renewable resources, prevents resource from irreversible shortage occur；Its
Secondary also to prevent mud, cinder, these waste materials of construction waste pollute ecological environment or living environment, without independent again
These waste materials are handled, ecological environment is not only strengthened, also effectively reduce the processing cost to waste material, municipal administration is reduced and throws
Enter；Reinforcing fibre is polymerized by multiple fiber, for comparing single fiber, has the characteristic and high intensity of multiple fiber
Toughness, effectively improve be made after concrete tension, bending resistance, shearing strength.
Further, the waterproof additive is made of the material of following parts by weight: 5-10 parts of water-reducing agent, calcium stearate 3-
5 parts, 3-5 parts of dispersing agent, 2-3 parts of magnesium lime, 1-2 parts of swelling agent；It can be reduced in concrete preparation process by water-reducing agent
Water consumption, calcium stearate and swelling agent can increase the swelling volume of concrete effectively when concrete is hardened, to prevent from mixing
Solidifying soil it is really up to the mark and there is a situation where dry and cracked, joint filling effectively is carried out to cement；To by water-reducing agent, calcium stearate, swelling agent it
Between cooperation, effectively realize the reduction of water consumption, while the case where cracking will not be caused because water consumption is very few again.
Further, the magnesium lime is the lime stone of the ingredient containing following mass percent: CaO >=49%, H2O
≤ 0.5%, MgO >=3.8%, SiO2≤1.5%,S≤0.035%。
In conclusion the invention has the following advantages: using mud, cinder, the materials such as construction waste prepare water
Cement concrete reduces the waste to non-renewable resources, prevents resource from irreversible shortage occur；Secondly it can also prevent from becoming silted up
Mud, cinder, these waste materials of construction waste pollute ecological environment or living environment, without again individually to these waste materials into
Row processing, not only strengthens ecological environment, also effectively reduces the processing cost to waste material, reduces municipal administration investment.
