Abstract
The light hollow brick is made up of powdered shale, saw dust, and powdered coal ash through sintering and features low cost, light weight, thermal and audio insulation, and anticorrosion nature. It is specially suitable to build up partition and filling wall of frame building.
Description
The present invention relates to a kind of building brick and production method thereof, specifically a kind of shale lightweight hollow brick and production method thereof, it is specially adapted to build by laying bricks or stones infilled wall, partition wall and the non-bearing wall body of frame structure building.
For now, infilled wall, the partition wall of industry and covil construction skeleton construction, mostly adopt the slag holllow building block to make materials for wall, though the application of slag holllow building block in building trade at present is still more extensive, but because the intensity of slag holllow building block own is low and it is bigger to be subjected to temperature to influence distortion, cause wall body slit easily, have a strong impact on construction engineering quality, on using, certain restriction is arranged also, especially recently confirmed that the slag holllow building block contains the gamma-rays of trace, to people's physical and mental health formation potential threat.Building trade is just being sought the wall body building material that a kind of energy substitutes the slag holllow building block.Recently some wall body building materials have been developed, for example: Chinese patent CN1041928A discloses a kind of " non-fuel autoignition sintered brick ", its feature is to be main raw material with clay or shale ore (account for weight 70～95%), waste coal ash (account for weight 5～30%), add fusing assistants such as an amount of feldspar in powder and ferric oxide red powder again, controlled temperature autoignition sintered forming under 950～1050 ℃ condition; Chinese patent CN1078450A discloses a kind of " energy-saving clinker brick ", its feature is to be main raw material with clay or shale (account for weight 60～70%), waste coal ash (account for weight 30～40%), add an amount of additive again, sintering temperature at 800～900 ℃ forms, though " non-fuel autoignition sintered brick " and " energy-saving clinker brick " can both be used as materials for wall, but clay or amount of shale are big, and the land occupation resource is more, and the building block capacity of making is bigger.
The objective of the invention is to propose a kind of lightweight, insulation, heat insulation, sound insulation, prescription advanced reasonably shale lightweight hollow brick and production method thereof.
The objective of the invention is to realize by following technical solution:
A kind of shale lightweight hollow brick, it is a raw material with shale powder, flyash, sawdust, forms by following prescription sintering,
Prescription (by weight):
Shale powder 40～60%
Flyash 20～40%
Sawdust 15～30%
Water is an amount of.
The method of producing shale lightweight hollow brick is to carry out according to the following steps successively:
1. prepare burden: the shale crushing screening is promptly got shale powder, add shale powder, flyash, sawdust, add an amount of water again and stir by prescription,
2. base: size is squeezed into base in accordance with regulations, the cool base of natural ventilation,
3. sintering: controlled temperature is a sintering 15～20 hours under 950～1100 ℃ the condition, sawdust carbonization in sintering process in the base substrate, form the fine eyelet of even compact in base substrate, the product that makes like this has lightweight, insulation, heat insulation, sound insulation, freeze proof function
4. cooling discharge promptly gets the shale lightweight hollow brick product.
Shale lightweight hollow brick and production method thereof that the present invention proposes, it is that the raw material sintering forms with shale powder, sawdust, flyash, reduced the consumption of shale, can economize the land resource, manufacture craft is simple, production cost is low, the building block of producing by the present invention has lightweight, insulation, heat insulation, sound insulation, freeze proof, corrosion resistant advantage, is specially adapted to build by laying bricks or stones partition wall, the infilled wall of transverse frame buildings, is a kind of material of construction of alternative slag hollow brick.
Embodiment:
A kind of shale lightweight hollow brick, it is a raw material with shale powder, flyash, sawdust, forms by following prescription sintering,
Prescription (by weight):
Shale 50%
Flyash 28～32%
Sawdust 18～22%
Water is an amount of.
The method of producing shale lightweight hollow brick is to carry out according to the following steps successively:
1. prepare burden: the shale crushing screening is promptly got shale powder, add shale powder, flyash, sawdust, add an amount of water again and stir by prescription,
2. base: size is squeezed into base in accordance with regulations, the cool base of natural ventilation,
3. sintering: controlled temperature is a sintering 16 hours under 950～1100 ℃ the condition, and in sintering process, the intravital sawdust carbonization of base forms the fine eyelet of even compact, and the building block that makes like this has lightweight, insulation, heat insulation, sound insulation, freeze proof function,
4. cooling discharge promptly makes shale lightweight hollow brick.
