Description
Technical field
The invention belongs to structure material technical field, more particularly to it is a kind of non-burning brick and its preparation method and application.
Background technique
Currently, the immediate prior art: existing entity enclosure wall especially substation's entity enclosure wall is substantially using burning
Shale brick block is tied, but has the drawback that 1, sintering shale brick block dimensioning after sintering using sintering shale brick block
Very little deviation is larger, buckling deformation is serious, face checking, color difference are larger, the easy accumulation of salt in the surface soil, influences enclosure wall masonry quality and perception effect；
2, the raw material of sintering shale brick are clay, shale, gangue or flyash, and a large amount of exploitations of raw material destroy hillside fields and plant
It is even ploughed, is unfavorable for environmental protection；3, sintering shale brick block make when need to through molding and two processes of high temperature sintering,
Middle sintering process energy consumption is high, while fire coal can generate a large amount of carbon dioxide, pollutes environment；4, sintering shale brick block generally by
Fixed plant produced, when use, need to transport to ground is used, apart from indefinite.The transport and loading/unloading vehicles process of long range, are easy to collide with
And abrasion, increase unqualified building block quantity, need the concrete block masonry for selecting presentation quality qualification in building process, labor intensive and
Material resources；5, colliding with and wearing etc. and cause the wall perception being built into poor because of sintering shale brick, need to be to enclosure wall to improve enclosure wall effect
Two-sided plastering increases construction cost.
In conclusion problem of the existing technology is:
(1) geometric dimension deviation is larger after sintering, buckling deformation is more serious, face checking, color for sintering shale brick block
Larger, the easy accumulation of salt in the surface soil of difference, influences enclosure wall masonry quality and perception effect.
(2) raw material of sintering shale brick are clay, shale, gangue or flyash, and the exploitation of raw material destroys
Hillside fields vegetation even ploughs, and is unfavorable for environmental protection.
(3) need to be through molding and two processes of high temperature sintering when sintering shale brick block makes, wherein sintering process energy consumption is high,
Fire coal can generate a large amount of carbon dioxide simultaneously, pollute environment.
(4) sintering shale brick block is generally by fixed plant produced, and when use need to transport to scene, apart from indefinite.It is long away from
From transport and loading/unloading vehicles process, be easy to appear and collide with and wear, increase unqualified building block quantity, when masonry needs to select outer
The concrete block masonry of appearance quality qualification, labor intensive and material resources.
(5) because sintering shale brick block collide with and to wear the wall perception for causing to be built into poor.
Solve the difficulty of above-mentioned technical problem:
1, there is sintering shale brick block itself material property the accumulation of salt in the surface soil can generate foam under long-term rain erosion
And moss, inevitably influence enclosure wall appearance.
2, factory's mass production, the sintering shale brick with batch different location can generate color difference, and different batches color is brighter
It is aobvious.The brick sintering plant of different regions and the different brick fields of areal, because of raw material drawing difference, finished product detection difference of dispatching from the factory,
It is difficult to be uniformly controlled on final product quality.The production process of fired brick is needed through overmolding and two stages of sintering, two processes
It is completed in different places with the time, causes quality that should not control.The inevitable hillside fields vegetation of the composition of the raw material of sintering is even ploughed
Ground；High temperature sintering engineering can inevitably discharge carbon dioxide and cause environment dirty.
Solve the meaning of above-mentioned technical problem:
1, conventional sintering shale brick is solved and has that geometric dimension deviation is larger, buckling deformation is serious, face checking, color difference
The defects of larger, easy accumulation of salt in the surface soil, improves clear water enclosure wall masonry quality and perception effect.
2, non-burning brick to be suppressed by cement, rubble powder, river sand, flyash and water weight proportion, simple process avoids
High-temperature sintering process protects arable land, energy conservation and environmental protection.
Summary of the invention
