Description
Technical field
The present invention relates to environmental protection brick body technique field, more particularly to a kind of coal ash heat-preservation brick and its production method.
Background technology
Flyash is one of larger industrial residue of the current discharge capacity in China at present, and China's year bed drain purge is up to 3000 at this stage
Ten thousand t.With the development of power industry, the flyash discharge capacity of coal-burning power plant increases year by year.Substantial amounts of flyash is untreated, just
Can produce airborne dust, pollute air, river can be caused to silt up if being discharged into water system, and toxic chemical substance therein can also to human body and
Biology damages.Therefore, the processing of flyash and Utilizing question cause people widely to pay attention to.The advantages of flyash uses exists
Adding coal ash has saved substantial amounts of cement and fine aggregate in concrete；Increase the modified of concrete.Build currently on the market
Material and ornament materials species are various, and insulation material also emerges in an endless stream, and complex production process causes expensive, and some can also be dirty
Environment is contaminated, is unfavorable for producing in batches and exploits.Based on this, a kind of coal ash heat-preservation brick and its production method are now studied.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of coal ash heat-preservation brick and its producer
Method.
The present invention is achieved by the following technical solutions：A kind of coal ash heat-preservation brick, it is characterised in that including following heavy

One of preferred embodiment as the present invention, the raw material is：50 parts of flyash, 15 parts of lime stone, middle sand
15 parts, 7.5 parts of stone, 5 parts of light-weight aggregate, 0.3 part of additive.
One of preferred embodiment as the present invention, the light-weight aggregate are cinder, the bottom slag that particle diameter is less than 5mm.
One of preferred embodiment as the present invention, the particle diameter of the stone is in the range of 5mm-10mm.
One of preferred embodiment as the present invention, the modulus of fineness of the middle sand is between 2.3-3.0.
The invention also discloses a kind of production method of coal ash heat-preservation brick, it is characterised in that comprises the following steps：
(1) by the raw material of parts by weight：Flyash 40-60 parts, lime stone 10-20 parts, middle sand 10-20 parts, stone 5-10 parts,
Light-weight aggregate 4-6 parts, additive 0.2-0.4 parts put into coagulation machine and stirred；
(2) well mixed material is put into mould again；
(3) vibration equipment is compacted, and the then demoulding forms building block；
(4) finally put into furnace, 1000-1100 DEG C of firing temperature, soaking time 80-100min, finished product of coming out of the stove.
The present invention compared with prior art the advantages of be：The present invention is green, and developing brick body using flyash is not only
Total utilization of PCA provides a kind of new approach, and is a kind of compensation to the brick-making raw material of growing tension, has very big
Economic and social benefit.Insulating brick density prepared by the present invention is 0.55g/cm3, the porosity 58.8%, thermal conductivity factor is
0.13W/m.k, mean compressive strength 4.0MPa, meet the use standard of national building heat preservation brick.
