Description
Art:
The invention belongs to the technical field that high-performance composite materials for building make, be specifically related to a kind of high performance composite
Material activation superfined flyash preparation technology and application.
Background technology:
China's power industry is based on thermal power generation, and wherein coal fired power generation is occupied an leading position.According to statistics, whole nation coal fired power generation
Year discharge coal ash of standing reaches more than 300,000,000 ton, utilization rate wretched insufficiency, and substantial amounts of flyash is piled up and do not only taken up a large amount of arable land, also pollutes
Environment.Therefore, the comprehensive utilization of flyash is related to the sustainable development of China's power industry and related industries.The length of flyash
Phase piles up and environment causes destruction greatly, therefore within the period that modern later is considerably long, does the comprehensive utilization of flyash well
With, for reducing the industrial residue pollution to environment, turn harm into good, turn waste into wealth and save the energy and natural resources etc., all have
There is profound significance.
Flyash is nowadays widely used in building materials industry, and especially in cement and concrete, this is the biggest
The effective way of ancestor's digestion flyash.But, now it is applied to the flyash in cement and concrete the most not at processing
Reason, added value is relatively low, and volume is all within 50%, and utilization rate is relatively low.How to prepare the flyash of high effector function, improve powder
Coal ash volume in cement, is the R&D direction deepened and utilize flyash.
Summary of the invention:
The present invention is for overcoming above deficiency, it is provided that a kind of by former flyash is carried out superfine grinding process, physics swashs
Send out and chemi-excitation, improve flyash activity, increase pure clinker aggregate portland cement or the commerical ready-mixed concrete of doping quantity of fly ash, it is achieved
Early strength increases fast, and early strength is high, and workability is good, and durability is high, and later strength increasing degree is big, the high-performance of low cost
Composite activation superfined flyash preparation technology and application.
The present invention is achieved in that described high-performance composite materials activation superfined flyash preparation technology and answers apparatus
Preparation process technology is as follows:
To meeting three grades of flyash of national standard JC/T409-2001 " silicate building products flyash " or two grades
Raw material powder coal ash, to former flyash storehouse, is then put into bistrique air flume, by bistrique air by flyash air pump after metering
Skewed slot delivers into bistrique elevator, is lifted into ultra-fine ball mill through bistrique elevator, adds in bistrique porch and accurately claims
The exciting agent of flyash weight 0.8% of amount, the grinding aid of 0.05%, flyash is milled into semi-finished product in ball mill, and half
Finished product sends into mill tail elevator through mill tail air flume, enters powder concentrator through mill tail elevator, and the fine powder selected is through bag type dust collection
Device becomes standard compliant finished product after gathering dust, meet less than 10 μm particles ratios more than 95%, be conveyed into into by finished product
Product storehouse, non-compliant semi-finished product return to bistrique elevator, enter described ball mill and again grind, select powder, gather dust.Warehouse for finished product
In superfined flyash high performance composite can dispatch from the factory or be packaged into bag by tank car is in bulk.
1. now producing 10-20% in 32.5 cement by mixing outside the present invention, mix homogeneously is tested, tested cement gel
The each age strength of sand test block is held essentially constant, and cement grade is constant, and cost reduces 10-20 yuan/ton；Existing by mixing outside the present invention
Producing 10-15% in label 42.5 cement, mix homogeneously is tested, and each age strength of tested cement mortar test block is protected substantially
Holding constant, cement grade is constant, and cost reduces 15-30 yuan/ton.
2., by the pure clinker aggregate portland cement mixing label 52.5 outside the present invention, mix homogeneously produces 42.5 and 32.5 water
Mud.Outer incorporation 40-50% mix homogeneously, can produce 42.5 cement, and outer incorporation 60-70% can produce 32.5 cement.Produced water
Mud is higher than ordinary fly ash portland cement early strength, and gain in strength is fast, and workability is good, and durability degree is high, and later strength increases
Amplitude is big, reduces 30-60 yuan/ton than common complex cement cost.
3. the present invention is used in C40 and C30 label commerical ready-mixed concrete, substitutes selecting crude drugs with winnower ash, the gelling material such as breeze and cement
Material, substitutes volume 50-70%, and 28 days strength ratio normal concrete intensity exceeds 3-6MPa, and cost declines 10-30 unit/m3, its stream
The performances such as dynamic property, slump, workability are superior to former normal concrete.
The present invention compared with prior art have fly-ash-contained greatly, mobility, slump, workability are good, durability degree
Height, later strength increasing degree is big, the advantage reduced than common complex cement cost.
Detailed description of the invention:
To meeting three grades of flyash of national standard JC/T409-2001 " silicate building products flyash " or two grades
Raw material powder coal ash, to former flyash storehouse, is then put into bistrique air flume, by bistrique air by flyash air pump after metering
Skewed slot delivers into bistrique elevator, is lifted into ultra-fine ball mill through bistrique elevator, adds in bistrique porch and accurately claims
The exciting agent of flyash weight 0.8% of amount, the grinding aid of 0.05%, flyash is milled into semi-finished product in ball mill, and half
Finished product sends into mill tail elevator through mill tail air flume, enters powder concentrator through mill tail elevator, and the fine powder selected is through bag type dust collection
Device becomes standard compliant finished product after gathering dust, meet less than 10 μm particles ratios more than 95%, be conveyed into into by finished product
Product storehouse, non-compliant semi-finished product return to bistrique elevator, enter described ball mill and again grind, select powder, gather dust.Warehouse for finished product
In superfined flyash high performance composite can dispatch from the factory or be packaged into bag by tank car is in bulk.
