Abstract
The invention discloses a kind of methods using straw ash production superfine cement powder, it is by weight percentage the waste residue straw ash 100% to be discharged after crop straw power generation, outer addition auxiliary material 2-3% water-reducing agent is through mixed-forming, it stirs evenly, it is sent directly into the levigate superfine cement powder product that specific surface area is made and is greater than 450-550 ㎡/kg of flour mill, and 50-60% can be directly substituted for cement products, improve the performance of cement products, improve strength of cement, specific surface area, reduce the water requirement of cement products, increase cement compatibility, improve the wearability of cement, clinker is saved, power consumption is saved, reduce manufacture of cement cost, protect environment.
Description
Technical field
The present invention relates to industrial residue straw ash production superfine cement powder technical field or environmental technology fields, more particularly to
A method of superfine cement powder is produced using industrial residue straw ash.
Background technique
As the reform and opening-up of China's economy puts more effort, vast agriculture personnel collect city, people in the countryside
With regard to fewer and fewer, a large amount of agricultural crop straw stacks such as mountain, for this purpose, country encourages enterprise to be sent out using various agricultural crop straws
Electricity, the waste residue straw ash being discharged after power generation about have 78,000,000 tons or so every year, they contain a certain amount of potassium sodium and calcium, silicon,
Aluminium component, and less than 10%, a large amount of straw ash is leaned on to be stacked and is filled into using farmland these straw ash utilization rates at present, it is serious dirty
Groundwater resources are contaminated, the waste water after meeting rainy day leaching tide, Heisui River flows directly into korneforos, polluted water resource, and fine day one is blown to the wind
A piece of grey black all over the sky, seriously polluted atmospheric environment, this is one of power generation factory owner's evil, therefore, recycling, minimizing, innoxious
It is the direction developed at present using stalk waste slag research and development novel product.So the present invention is produced using advanced technical matters
A kind of superfine cement powder product, be carry out a kind of recycling, minimizing and the method for harmless treatment, have it is environmentally protective
A kind of method using industrial residue straw ash production superfine cement powder, the problem of being the of the invention environmental pollution of being solved.
Summary of the invention
In view of the deficiencies of the prior art, superfine cement powder is produced using stalk waste slag the object of the present invention is to provide a kind of
The method of product, tool technology is advanced, and rationally structure is simple, and 100% utilizes straw ash in technique, and low energy consumption, attached value
Height, advantage without secondary pollution are conducive to the protection of environment.
In order to achieve the above object, the technical solution adopted by the present invention is that: it is a kind of to produce ultra-fine water using stalk waste slag
The method of mud powder, production method include the following steps:
1. stock: using the waste residue straw ash being discharged after crop straw power generation, adding auxiliary material water-reducing agent；
2. ingredient and molding: being by weight percentage 100% by waste residue straw ash, the ratio of outer addition water-reducing agent 2-3% carries out
Mixed-forming.
3. stirring and grinding: the good material of mixed-forming being stirred uniformly, and is sent into flour mill progress and levigate ratio is made
Superfine cement powder of the surface area greater than 450-550 ㎡/kg is to get superfine cement powder product；
4. the proportion of superfine cement powder substitution: by levigate good superfine cement powder product, directly substitution 50-60% is produced for cement
Product use.
The effect that the present invention obtains is:
1. superfine cement powder product produced by the invention, can directly substitute cement products 50-60% use, significant effect is improved
The various performances of cement products, improve strength of cement 10-15mpa, improve 90 ㎡ of specific surface area/kg, increase cement phase
Capacitive 120mm improves 9-18 times of wearability of cement products, reduces the water requirement 20% of cement products, it is ripe to have saved cement
Material 50%, has saved power consumption 40%.
2. raw material of the present invention are using 100% waste residue straw ash entirely, production cost is very low, can save cement cost 95
Yuan/ton.
3. the present invention is that the waste residue straw ash of crop straw power generation factory discharge solves outlet, a kind of new skill is provided
Art innovative product protects environment not contaminated, at the same for cement production enterprise saved a large amount of natural resources lime stone, clay,
The materials such as coal, gypsum.
4. the method for the present invention has technology advanced rationally simple, low energy consumption, attached value is high, with low investment, without secondary dirt
Dye, has a good application prospect.
Specific embodiment
A method of superfine cement powder being produced using industrial residue straw ash, straw ash of the invention produces superfine cement
It is 100% for raw material that the material of powder, which is with the waste residue straw ash being discharged after crop straw power generation, additional to be aided with water-reducing agent material
Material is formed through special process production superfine cement powder, and process includes the following steps:
Embodiment 1:
A method of superfine cement powder being produced using straw ash, feature includes the following steps: using breaking-out object straw power generation
The waste residue straw ash being discharged afterwards is by weight percentage raw material for straw ash 100%, outer 2% water-reducing agent of addition auxiliary material
It through mixed-forming, stirs evenly, is sent directly into the levigate specific surface area that is made of flour mill progress and is greater than the ultra-fine of 450-550 ㎡/kg
Superfine cement powder product is directly substituted 50-60% and is used for cement products by cement powder to get superfine cement powder product, can be improved
Strength of cement 10-15mpa, 90 ㎡ of specific surface area/kg increase cement compatibility 120mm, improve the wearability 9-18 of cement products
Times, cement products water requirement 20% is reduced, clinker 50% is saved, saves power consumption 40%.
