Description
Technical field
The invention belongs to the field of building materials, in particular to a kind of pressure-resistant fired brick.
Background technique
In construction industry, materials for wall is the important composition part of construction industry, and consumption of the materials for wall in building materials is most
Greatly.In recent years, with the propelled at high velocity of urban construction, the every annual consumption of wall body brick consumes soil about 66 at 600,000,000,000 pieces or more
Ten thousand mu, 90,000,000 tons of coal of consumption mark.Under environmental requirement and the double action of Policy Conditions, novel wall material is promoted, is reduced
Clay brick production capacity is eliminated in stockpiling land occupation, and Economization on land is the trend of the times of environmental requirement, the environmental protection innovation gesture of materials for wall industry
In certainty.Increasingly rare with land resource, most area has abandoned the scheme that wall body brick is produced using clay.And
Propose the method for producing materials for wall as raw material using industrial solid castoffs such as mine tailings, building waste, clinkers.It is existing to adopt
With the production methods of the materials such as building waste, clinker substantially be used to produce autoclave aerated concrete building block (or for aerated blocks,
Steam-pressing brisk), the scheme of water-permeable brick, the no-firing bricks such as cement brick, but these bricks are much inferior to fired brick, and through investigating, we are seen
It is largely built based on sinter walling materials into energy saving building.The rural housing construction in remote mountain area is mostly with reality
Based on heart brick；Away from the closer rural area in city based on sintered perforated brick and porous building-brick material；Sintered hollow block and
Building-block, sintering heat-reserving brick and insulation blocks are then applied to the weight bearing area and skyscraper of the tier buildings of big and medium-sized cities
Non-weight bearing area.Sintering heat insulation building block is that the development of Europe the 1940s is faster a kind of with preferable thermal and insulating performance
Materials for wall.Early 1980s begin, and tens of sintered hollow block production lines are introduced, since various problems all do not develop
It is good, it promotes within 1997 a kind of novel energy-conserving of sintering heat-reserving brick and insulation blocks for the purpose of substituting clay solid brick and is sintered material
Material, development process are very slow.It is only 20,000,000,000 pieces to sintered hollow block gross annual output amount in 2000, accounts for fired brick total output
2.7%；Till now from walling innovation, after development in more than 20 years, sintered hollow block accounted for brick gross annual output up to 270,000,000,000 pieces at present
The 30% of amount；Sharp waste includes colliery wastes brick, flyash brick and product (the being mostly porous brick) year for adding 30% or more waste residue
250,000,000,000 pieces of total output, account for the 27% of brick gross annual output amount.The materials for wall innovation that wall material industry experienced more than 20 years is saved with building
Workable propulsion, materials for wall develop to diversification, multi items, multifunctional direction.Sintered article is from technique, technology, equipment
Deep variation also has occurred to product, product variety develops to porous brick, hollow brick, hollow building by single clay solid brick
Block, composite insulating brick, decorative brick, paving brick, decorative panel etc..The performance and function of product are also more in line with building energy conservation, environment
It protects, the requirement of comprehensive utilization of resources, has energy conservation, the characteristic that benefit is useless, environmentally friendly.The thermal coefficient of materials for wall is lower, protects
Warm heat-proof quality is better.Under normal circumstances, the thermal coefficient of materials for wall is directly proportional to density, therebetween about linear relationship.
This is because the thermal coefficient of solid material is more much bigger than air, therefore, the hole in material is smaller, and density is bigger, thermally conductive
Coefficient is bigger, and thermal and insulating performance is just poorer.It is vice versa.The porosity of ordinary fired brick causes thermal insulation property poor,
It is such as used for Self-thermal-insulation System, energy-saving design in construction requirement is not able to satisfy, heat insulating material for external must be added.Due to needing plus smearing heat preservation
Layer, constructing, inconvenient and cost is higher, the duration is longer.Existing fired brick technical field, coal gangue baked brick centre are hollow knot
Structure, load-bearing and heat insulation effect are bad, and existing coal gangue baked brick outer surface is not beautiful enough, cannot reach preferably decoration effect
Fruit, and these fired bricks cause resistance to pressure poor because its own structure porosity is low and interior mechanics performance is poor, thus in application surface
Aspect is much limited.
